Motion Control Application – Polishing Machine’s Linear Ball Bearing Failures Solved by LM76!

Motion Control Application – Truck Wheel Buffing Machines

motion control - lm76 application

motion control - linear motion products

 

The Application –

Motion Control – Polishing Aluminum Truck Wheels is done with a polishing machine that has a 36″ vertical stroke indexer, having a 2500 pound load moving @ 4″ per second. The polishing media is like toothpaste with glass in it. It is extremely abrasive, and sticky/tacky.
motion control - wheel buffing

The Problem –

The industrial buffing system is chewing-up motion control linear ball bearings and spitting them out every 2 weeks! This is the situation one of customers found themselves in while for years accepting lost production and costly maintenance shutdowns. When LM76 got a call from a proactive new maintenance manager, we were eager to try a scraper seal design we had recently had success with on another application.

Originally, these systems came with protective bellows which helped keep polishing media from contaminating the 2″ linear ball bearing pillow blocks. According to our maintenance manager, once a bellow was damaged, it was removed and thrown away. Maintenance personnel so disliked having to take off and reinstall bellows that they mysteriously disappeared. Even with protective bellows, aluminum dust mixed with polishing media formed what one mechanic termed, “toothpaste with glass in it.”This abrasive “lapping compound”would stick to shafting, dry and semi-harden. As a bearing rolled along, polishing media would penetrate it’s seals “sliming” balls and clogging ball tracks. This would quickly lead to bearing failure and shaft brinneling (grooving). Needless to mention, routinely replacing linear ball bearings and more costly shafting was too much for the new maintenance manager who called LM76 for help.

The Solution –

motion control - black racer bearing

For this application, we chose our motion control Black Racer Ceramic Coated Linear Bearing. This bearing is extremely tough, is of one piece construction (no mechanical components, no catastrophic failure mode or shaft grooving) and has the longest life test we know of on record. Like linear ball bearings, Black Racer requires lubrication.

John Tarbell (President of LM76), specified a zero clearance beryllium copper scraper seal. Beryllium copper is exceptionally ridgid, extremely hard and wear resistant. The Beryllium copper would trap lubricant and distribute it as a fine, uniform film on the shaft. This film reduces friction, disperses heat and wets shafting. The wetted shaft surface forms a barrier between media and steel – keeping polishing media from cleating into disparities on the shaft (remaining peaks and valleys). Tarbel, said, “A Zamboni doesn’t lay down an inch of ice, it fills in the skate marks.” When the scraper travels on the shaft, it easily lifts the media and moves it along to the end of the stroke. Unlike linear ball bearings, Black Racer has no balls so some residual “slime” is easily accommodated. (Seen below, the beryllium scraper seal is captured between the bearing counter-bored face and the machined steel end cap.) Admittedly, a heavy interference fit dramatically raised system friction but was mitigated because the system is hydraulically driven – driving force is not an issue.

Staying within the form factor of the original OEM design–standard roundway pillow block and shafting–we chose our direct drop-in 2″ closed pillow block and Black Racer Ceramic Coated bearing coupled with our 2″, Class L Rc60 Case Hardened Shafting. Tarbell then designed a steel end cap retainer ring that pinned the beryllium scraper seal against the bearing face.

Note: The bearing leading and trailing faces have machined counter-bores to locate and capture the back of the scraper seal. To keep the retainer ring secured to the pillow block, set screws were positioned on both sides and driven into a slot machined into the OD surface.

Motion Control – FDA/Dairy Washdown System

motion control - lm76

 

E. Longmeadow, MA – — Motion Control – Application  – Dairy machinery manufacturers are under intense scrutiny by FDA inspectors when it comes to FDA material and caustic washdown compliance. Recently, LM76 was called by a large US dairy packaging company to review a problematic portion of their filling line. After each shift, the filling line is washed-down, has a caustic foaming agent applied to kill bacteria and then is final rinsed. The caustic foaming agent was destroying – literally eating – the aluminum shaft supports while shafting exhibited pitting and showed signs of minor corrosion. Additionally, there were areas where product got trapped and these locations were havens for bacterial growth. Because this system was in-place and our customer was the end-user, LM76 engineers had to use direct drop-in replacement com¬ponents. What to do?

Motion Control – CERAMICSPEED Bearing Units Are FDA Compliant!

Motion Control – Ceramic Radial Bearings are FDA Compliant

E. Longmeadow, MA – LM76 is continuing to expand its FDA compliant radial and linear bearing product lines. CERAMICSPEED Bearing Units are the latest additions. Bearings used in the food and beverage industry have to be reliable, easily cleaned, and require only minimal maintenance. CERAMICSPEED Bearing Units featuring FDA-approved Si3N4 (Silicon Nitride) balls have extremely long service life as Si3N4 balls are 2 times harder than steel balls and 4 times smoother.

motion control - linear motion products

This means, CERAMICSPEED Bearing Units handle higher loads with less friction, resulting in longer life of the balls and the race. Balls made from Silicon Nitride do not change their shape under load and are not subject to spalling which can contaminate the foods or beverages being processed. They are also very tolerant of temperature extremes (-30OC to 100OC) and thermal shock.

Linear Motion – The above twin Linear slide system was designed for a large manufacturer of semiconductors. The vapors from a plating operation were so corrosive that linear components were failing within months of installation. LM76 designed a motion control system which was predominately stainless while some components were nickel plated.  LM76’s polymatrix, ball screw nut was a major improvement over a competitor’s system which employed a standard re-circulating ball nut.
