FAQ - Single-Point Lubricators
  1. Q: What greases are available with Timken lubricators?
    A: Timken offers over 120 different greases and oils, including the complete line of Timken quality grease products.

  2. Q: Can you explain more about the chemical reaction in your chemical/gas units?
    A: The electrolyte solution in the G-Power lubricator is a citric acid-based solution. The pH of this solution is 4.5, which is less acidic than the normal soft drink. The chemical process starts when the activating pellet comes in contact with the electrolyte. This forms a gas (hydrogen) that creates the pressure to push the piston. The volume of gas created is very small. As reported by the Canadian Explosive Atmosphere Laboratory Fuels Research Centre, the amount of gas is so small that even if it were tested to destruction, the amount of gas released would be too small to be of a flammability or explosive hazard concern.

  3. Q: How do I know the lubricator needs to be changed out?
    A: You will be able to see the red nylon piston through the unit's clear nylon cap in the Timken G-Power Model 101 and 103 units. The G-Power Model 102 and all M-Power units have plastic housings so the status of the lubricant is always apparent. Also, adding the lubricator installation and changeout dates to your customer’s preventative maintenance program/calendar will take the guesswork out of the changeouts.

  4. Q: Will hot or cold temperatures affect the flow rate?
    A: Timken G-Power flow rates are based on a 78° F ambient temperature. Consistent warmer or colder temperature will speed up or slow down the flow rate since G-Power operates via a chemical reaction. You may have to adjust the units based on your operating temperature. For example, if your bearings require a Timken 3-month unit and your average temperature is over 100°F, then you simply select a Timken 6-month unit and that will regulate the flow equal to a Timken 3-month. Do just the opposite in colder temperatures.

    M-Power on the other hand is temperature independent and rated for 14°F to 122°F.

  5. Q: Can I remote mount Timken single-point lubricators?
    A: Yes, but follow the installation guidelines closely. You must use ¼" pipe or 3/8" hose/tubing when remote mounting a Timken single-point lubricator.

    Timken M-Power can be remotely mounted up to 10 feet regardless of the lubricant discharge setting.

    Timken G-Power remote mounting distance is based on the discharge setting and model.

  6. Q: Can units be refilled?
    A: G-Power: No. Units should be removed and disposed with standard grease wastes once empty.

    M-Power: The lubrication canister (LC) cannot be refilled, but the drive unit may be reused. You can change out the LC in the field and replaced it with a filled LC reservoir available from Timken. When the LC is changed, the battery pack must also be changed out.

  7. Q: What is the expected shipment for units once ordered?
    A: Standard lead time is 7-10 business days.

  8. Q: May I mount a Timken lubricator in any direction?
    A: Yes. Units may be mounted in any direction. We recommend the M-Power units be supported with a bracket if mounted in any position other than standing vertical or hanging vertical. Also, M-Power units are not to be mounted at more than a 90 degree angle. The reason for this is that there is the possibility of the lubricant seeping into the drive unit and contaminating the electronics.

  9. Q: How do Timken single-point lubricators stand up to rust?
    A: Timken G-Power Models 101 and 103 come from the factory coated to help prevent rusting in most cases. The Timken G-Power Model 102 is a plastic unit, so rust is not an issue. This makes it an ideal unit for applications that are subjected to washdowns.

    Although a plastic unit, the Timken M-Power lubricator, which is treated at the factory for moisture and comes with a "wet cap", does not contain electronics which can be damaged by moisture.

    The Timken G-Power Model 101 is submersible and can be used in water up to 15 feed in depth.

  10. Q: Can you use Timken lubricators on electric motors?
    A: Yes. A 12-month setting is recommended for electric motors from 25 to 400 horsepower. For over 400 horsepower motors, a 6-month setting is normally used. In all motor applications, we strongly recommend that a 5-pound relief valve be used in place of the drain plug. This will let excess grease flow out of the motor. Note that the Timken lubricators do not produce enough pressure to push grease into the windings.

  11. Q: How much vibration will the Timken Lubricators withstand?
    A: The nylon front of the lubricator will enable the unit to withstand some vibration. If excessive vibration is seen, we recommend that the unit be remotely mounted and let the hose take the vibration.

  12. Q: If I have more than one Timken lubricator on a bearing, will all the units empty at the same time?
    A: No, but they will empty out within 1 to 2 days of each other. Normally the lubricator closest to the bearing will empty first, due to diffusion (i.e., going to the point of least resistance). When the red nylon piston shows on the first lubricator, it is time to change all units, as the others will be empty in a day or two.

  13. Q: If a bearing has two grease fittings, which one does the Timken lubricator go on?
    A: The main lubrication point is the fitting in the middle part of the bearing. This is where the main Timken lubricator should be installed. Normally the second fitting is used to lubricate the seal. On this point, we usually drop down two units than the main lube point has. That is, if the main lube point has a lubricator setting of 1-month, then we use a 6-month setting on the seal. Sometimes a bearing has two "main lube" points in the middle of the bearing. If you look at the bearing from the side, much as you would a clock, the points are normally at 10 o’clock and 2 o’clock. If the bearing is running clockwise, as most do, the lubricator needs to be installed at the 10 o’clock position so the grease can get in properly. At the 2 o’clock position, the back pressure from the bearing may keep the grease out of the bearing.

  14. Q: Can the Timken lubricator blow the bearing seal?
    A: No. It takes at least 240 psi to blow a seal. Timken single-point lubricators will generate 75 psi at the most, making it impossible to blow a seal. It is easy to blow a seal with a grease gun, which creates over 2,000 pounds of pressure. So, be careful.

  15. Q: If the seal is blown on a bearing, will the Timken lubricator empty sooner?
    A: No, but you will see grease coming out from the blown seal, creating a grease seal to help keep contaminants out.

  16. Q: What if the bearing is always covered with contaminants?
    A: This is a situation where no matter how much grease you have going into the bearing, it will never be enough. A bearing which is "gobbed out" will not allow heat to be displaced, resulting in high temperatures which melt the grease and lead to premature bearing failure. Always be alert for bearings in this situation to avoid possible problems.

  17. Q: Can I change the dip switch setting on the M-Power unit after it has been installed?
    A: Yes. The dip switch setting instructions are located on the label of the drive unit. Each time the unit is turned off and turned back on, the timer resets. Thus, if you reset the dip switches when the unit is half empty, the timer assumes you have changed the lubrication cartridge and will keep cycling until it cannot push the piston any further. Make sure to keep an eye on it so you know when it empties, or make a note in your changeout schedule.

  18. Q: Does the 1-month setting on the M-Power push out more grease during the same timer cycles?
    A: No, but the timer comes on more frequently. See the M-Power installation instructions for more details.

  19. Q: When the M-Power unit runs empty, I can order a filled canister to replace the empty one. What about batteries? Won't they run out of power eventually?
    A: Each time you reorder a filled lubrication cartridge it comes with a battery pack. ALWAYS replace the batteries when you change the lubrication cartridge.

  20. Q: M-Power units are a bit heavier than regular units. Should I use a bracket to support them?
    A: Every unit should be supported if it's going into a high vibration area. Or, often we can simply let the unit hang on a sturdy hydraulic hose, and the vibration doesn't affect the unit. Because of the M-Power’s heavier design, we recommend supporting it with a bracket whenever it's installed in any position other than vertical standing or vertical hanging.

  21. Q: When using an oil-filled G-Power unit, can I remote the unit and use a check valve?
    A: Yes. You can remote the unit (up to 12 feet or more for the 1-month unit!) but make sure you use the check valve (non-return valve or oil throttle) at the lube point. This prevents the line from draining empty and keeps a positive pressure in the line.

  22. Q: Can I use a fluid grease with your oil brushes?
    A: You can, but they wouldn't last long. No matter how fluid the grease is, all greases use thickener (soap) to transport the lubricant to the lube point. And this thickener will build up inside the brushes and eventually clog the brush.

  23. Q: Are your units explosion proof?
    A: The Timken G-Power is intrinsically safe.

  24. Q: Are your units UL approved?
    A: The Timken M-Power Model 300 is UL listed in the U.S. and Canada for Class l, Div 2; Class II, Div 2; and Class III hazardous locations.
