Automatic Lubricators for Electric Motor Bearings
A motor bearing needs a small amount of grease at a steady interval. A single-point automatic lubricator gives a fixed shot every few hours in place of a large charge from a grease gun every few months.

Why motors are fitted first
The maker's catalogue names over-greasing as the risk on motors: excess grease churns and overheats, and can reach the coils and windings. Under-greasing shortens bearing life. An automatic lubricator removes both by giving the calculated quantity in small shots.
The maker's method works out the quantity and interval for each bearing, with a separate calculation for electric motors, and the period setting on the unit follows from it.
Supplied to order. The maker's name, model number and data sheet are on the quotation. Every figure on this page is taken from the maker's catalogue; the maker may change specifications without notice, so the data sheet sent with the quotation is the one that applies.

How much grease each setting gives
| Period set on the unit | 60 ml cup, per month | 150 ml cup, per month | 250 ml cup, per month |
|---|---|---|---|
| 1 month | 60 ml | 150 ml | 250 ml |
| 2 months | 30 ml | 75 ml | 125 ml |
| 3 months | 20 ml | 50 ml | 83.3 ml |
| 4 months | 15 ml | 37.5 ml | 62.5 ml |
| 6 months | 10 ml | 25 ml | 41.7 ml |
| 12 months | 5 ml | 12.5 ml | 20.8 ml |
Each dispensing cycle delivers a fixed shot: 0.167 ml from a 60 ml cup, 0.417 ml from a 150 ml cup and 0.694 ml from a 250 ml cup. The period setting changes how often the shot is given, from every 2 hours on the 1-month setting to every 24 hours on the 12-month setting.
Motors that do not run all day
A standard unit dispenses on the calendar, whether or not the motor runs. The smart series can take an external DC supply that switches with the motor, so it greases only during running hours and resumes from memory after each stop. The maker's example: on a 6-month setting with the equipment running 8 hours a day, one cup lasts about 1.5 years.
Specifications
| Item | As stated in the maker's catalogue |
|---|---|
| Type | Single-point, motor-driven, battery-powered grease lubricator. One unit feeds one point. |
| Grease cup sizes | 60 ml, 150 ml and 250 ml; 500 ml in the smart series |
| Dispensing period | 1 to 12 months, set on DIP switches on the unit |
| Outlet pressure | 75–150 psi (5–10 bar), with output adapted to back pressure |
| Operating temperature | −20 to +60 °C. This is the limit of the drive; the grease must still pump at that temperature. |
| Grease outlet | 1/2" PT male |
| Power | 6 V lithium battery pack; the smart series can also run from an external DC supply |
| Size, height × diameter | 60 ml: 13.9 × 8.9 cm. 150 ml: 16.3 × 8.9 cm. 250 ml: 19.6 × 10.2 cm |
| Blockage warning | The unit monitors the feed and flashes a warning light if the line is blocked, the cup is empty or the battery is low |
| Grease | Maker's pre-filled cups, or an empty cup filled with your own grease |
Grease and upkeep
The cup can be filled with your own grease, so the grease already approved for the bearing stays in use. We supply it: see industrial greases and the grease compatibility guide before changing grease type.
The grease cup and the battery are replaced together at the end of each cycle. If the warning light flashes, check for a blocked line, an empty cup or a low battery. Use the maker's cups and battery packs; a lithium pack must not be recharged, opened or heated.
What to send for a quotation
For each point send the machine, the bearing designation, the shaft speed, the running hours per day, the ambient temperature and the grease now in use. The grease quantity and interval are then worked out per bearing, and the cup size and period setting follow from that.
For motors, add the frame size and whether the drive end and non-drive end are both greased. Each end is one point and takes one unit.
Terms
We quote on working days, usually the same day. Lubricators are supplied to order, so the lead time is stated on the quotation. Transit is 48–72 hours in South India and 5–7 days elsewhere after dispatch. Payment is in advance against a proforma invoice, and GeM orders follow GeM terms. Every order carries a GST tax invoice. Prices are on request.
Frequently Asked Questions
Does a motor need one lubricator or two?
One unit feeds one point. A motor greased at both the drive end and the non-drive end takes two.
Will it over-grease the motor?
The unit gives a fixed small shot per cycle, 0.167 ml from a 60 ml cup, and the period setting is chosen from the quantity calculated for the bearing.
What if the motor runs only one shift?
The smart series can take an external DC supply that switches with the motor, so it greases only while the motor runs.
Can I keep my present motor grease?
Yes. The maker offers an empty cup to fill with your own grease. We supply the grease.
How do I get a price?
Prices are on request. Send the points and quantities and we quote on working days, usually the same day.
Send your motor list
Send the motors, the bearing designations and the speeds. We quote on working days, usually the same day, with the lead time.
