Kluber motor grease is the manufacturer-recommended lubricant for the upper and lower bearings of the vibratory motor on a round separator. It is the grease your motor's own service manual calls for at every scheduled regrease interval, supplied in a 400 g pack.

The bearings in a vibratory motor do not live an easy life. They carry an eccentric weight spinning at 1,200 or 1,800 RPM, they take that load continuously rather than in bursts, and the whole housing is vibrating by design. A general-purpose shop grease is not built for that, and using one is one of the most common reasons a vibratory motor fails early.

One pack covers roughly five complete regreases on a VB-frame motor — on a machine running a single shift, that is two to three years of scheduled lubrication.

Manufacturer-Recommended Motor Grease vs. General-Purpose EP2 Shop Grease

The grease already on your shelf will physically fit in the fitting. That is not the same as being the right grease, and this is the single most common maintenance shortcut we see shorten a vibratory motor's life.

- Load rating — A vibratory motor bearing carries a rotating eccentric weight, so it sees heavy loading continuously rather than in bursts. Motor grease is built for that duty. Ordinary EP2 chassis grease is not.

- Vibration resistance — The entire motor housing is vibrating on purpose. A general-purpose grease can migrate out of the bearing under sustained vibration, which leaves it running dry long before the next scheduled service comes around.

- Interval integrity — Your motor's regrease interval was set by the manufacturer assuming the specified grease. Substitute a different product and the published interval no longer describes your machine, so the schedule you are following is now a guess.

- Mixing risk — Not all greases are compatible with one another, and the wrong combination can do more harm than running low would have. If something else has been used in these bearings, tell us when you call and we will walk you through it.

- Cost of being wrong — A pack of the correct grease is a fraction of what one bearing replacement costs once you add the labor and the lost production hours to pull and rebuild a motor.

The short version: use what the manufacturer specifies, in the quantity it specifies, at the interval it specifies. That is the whole maintenance program for the bearings.

• What it lubricates — the upper (top) and lower bearings of the vibratory motor on a round vibratory separator. Both bearings take the same. grease; only the quantity differs.
• Manufacturer recommended — this is the grease specified for these bearings, not a substitute or an equivalent.
• Documented schedule — VB-frame motors, models VB 12-2510 and VB 18-2510: 50 g in the top bearing, 25 g in the lower bearing, every 1,000 operating hours.
• Other frame sizes — quantities and intervals vary by frame size and model. Check the lubrication schedule in your motor's manual, or call us with your model number and we will look it up with you.
• Works with standard grease guns — applied through the motor's existing grease fittings; no special tooling required.
• Not sure what motor you have? The model number is on the motor nameplate. Send us a photo of it at support@screenerking.com and we will identify it.

• Lead Times: In-stock hardware item — contact us to confirm current availability.
• Shipping Options: Parcel shipping; ships with other parts on the same order.
• Expedited Shipping: Available upon request—contact us to prioritize your order.

• Scheduled 1,000-hour regreasing — the routine top and lower bearing service on a VB-frame vibratory motor.
• Preventive maintenance stock — kept on the shelf so the scheduled service actually happens on schedule.
• New motor commissioning — starting a replacement motor on the correct grease from hour one, so the manufacturer's interval applies from the beginning.
• Switching back from a substitute grease — returning a motor to the specified lubricant after a general-purpose grease has been used.
• Continuous-duty operations — food, chemical, mineral, and plastics lines running long hours, where 1,000 operating hours comes around several times a year.
• Multi-machine plants — one grease covering the separator motors across the floor rather than a different product per machine.

• Manufacturer recommended — specified for the upper and lower bearings on the separator's vibratory motor, so your regrease interval stays valid.
• Built for vibratory duty — made for a bearing carrying a spinning eccentric weight under continuous vibration, which is not what general-purpose grease is for.
• Covers both bearings — one product for the top and the lower bearing; only the quantity changes.
• 400 g pack — about five full regreases — on a VB-frame motor, one pack carries a single-shift machine roughly two to three years.
• Protects the expensive part — bearings are what fail first on a neglected vibratory motor, and replacing one costs many times what the grease does.
• Straightforward application — goes in through the motor's existing grease fittings with a standard grease gun.
• Backed by our 100% satisfaction guarantee — and by a team that will confirm the right quantity for your specific motor before you order.

Q: What grease does a vibratory separator motor take?
A: The manufacturer-recommended motor grease for its upper and lower bearings — this product. It is not a general-purpose shop grease, and using one voids the assumptions behind your motor's published regrease interval.

Q: How much grease goes in each bearing?
A: On a VB-frame motor (models VB 12-2510 and VB 18-2510), 50 g in the top bearing and 25 g in the lower bearing. Quantities differ on other frame sizes, so check your motor manual's lubrication schedule or call us with your model number.

Q: How often should I grease my vibratory motor bearings?
A: Every 1,000 operating hours on a VB-frame motor. For a machine running one shift, that works out to roughly twice a year; on continuous duty it comes around every six weeks or so. Other frame sizes have their own intervals.

Q: How many regreases will one pack cover?
A: About five complete services on a VB-frame motor — two to three years on a single-shift machine.

Q: Do the top and lower bearings take the same grease?
A: Yes. Same grease in both — only the quantity is different. The top bearing takes twice what the lower one does.

Q: Can I just use the EP2 grease we already have in the shop?
A: We do not recommend it, and it is one of the most common causes of early vibratory motor failure we see. A general-purpose grease is not made for a bearing carrying a spinning eccentric weight under continuous vibration. Greases are also not all compatible with one another, so if a substitute has been used
in these bearings, call us before you regrease and we will walk you through it.

Q: What happens if I skip a regrease?
A: The bearings are what fail first on a neglected vibratory motor. A missed interval does not usually show up immediately — it shows up as a bearing replacement, plus the labor to pull and rebuild the motor, plus the production you lose while it is down.

Q: I do not know my motor model. Can you help?
A: Yes. The model number is on the motor nameplate. Send a photo to support@screenerking.com or call 866-265-1575 and we will identify it and confirm the right quantity and interval for it.
