Application – In “Off-Roading” LM76’s Black Racer Bearing is a Winner!

LM76

Anyone who’s worked on cars knows how critically important ball joints are to steering and suspension. They also know what happens when ball joints fail!

Motion Control Application Ball Joint

 

E. Longmeadow, MA – — Motion Control – Application Story – When an aftermarket manufacturer of off-road steering and suspension systems needed an upper ball joint bearing, they called LM76. These systems are purchased by off-road vehicle owners who want to upgrade their OEM steering and suspension units for hard-hitting environments. Pounding, shock, sand and debris are all part of the mix when it comes to extreme off-roading and LM76 Black Racer bearings are right at home. According to company engineers, after a year of brutal testing, Black Racer met all design goals and exceeded expectations.

LM76's Linear Motion Black racer bearings

LM76’s high speed, “Black Racer,” ceramic coated linear bearings out perform linear ball bushing and linear polymer bearings in high speed and high acceleration/deceleration applications. These drop in replacement linear bearings are designed to be used in standard open and closed pillow blocks. “Black Racer” linear bearings are ideal for: Rocket sleds, crash test systems, and other high speed, high acceleration application.

Motion Control Application Ball Joint

Open and closed ceramic bearings are available in 12 inch sizes (0.250 in. to 4.000 in.) and 11 metric sizes (5 mm to 80 mm), and in LM76’s self aligning configuration, as well as their Lube/Plus DesignTM which incorporates an internal felt wiper to extend lubrication capabilities. A file hard RC 89 ceramic shell over an aluminum substrate has a coefficient of friction of .04 to .08 (1/3 the coefficient of friction polymer bearings), withstands up to 5000 PSI, 40,000 PV and unlimited SFM! Additionally, these bearings have a typical life expectancy of 100 million linear feet. Shafting options include RC60 steel shafting and other shafting options available from LM76.

LM76’s FDA/USDA Compliant Linear Bearings Are – “THE” Only Solution!

Linear Motion - Only Solutions - Cheese Packaging

 

 

 

E. Longmeadow, MA – — What do you do when you’re linear actuator bearings are including cheese debris? Particularly when your cheese slicing system requires FDA/caustic washdown compliance and FDA inspectors are on site reviewing all process operations for included debris which can propagate harmful bacteria.

 

 

 

“THE” Application

  1. Repeated Impact with Dense, Malleable Product
  2. FDA Compliant Materials
  3. Caustic Washdown
  4. Self-Lubricating
  5. No Product Inclusion

“THE” Issues

Linear Motion - Only Solutions - LM76 Linear Bearing

Originally, our customer specified LM76’s standard stainless, FDA/PTFE linear bearings in their linear actuator. This bearing met all the fundamental requirements: FDA/Caustic Washdown compliance, self-lubricating and no catastrophic (mechanical) failure mode. Initially, we felt the standard running clearance between bearing ID and shaft (.001 overall, .0005” either side) would be sufficient to clear debris. Not so. Thus, we needed a seal that would be FDA compliant, have a low “K” or wear factor and low coefficient of friction so drive torque wouldn’t be negatively affected. Since standard industry nitrile and buna seals were never in contention, we had to design a “scraper seal” from scratch.

 

 

 

 

 

“THE” Solution

Linear Motion - Only Solutions - LM76 Stainless Steel & PTFE Bearing

John Tarbell (President and Internationally regarded Plain Bearing Expert) reviewed several materials and selected Ertalyte® PET-P because it met all criteria relative to FDA/Washdown compliancy, “K” (wear) factor, coefficient of friction, machinablilty and thermal expansion/contraction. The ETX seals were designed for a slight interference between bearing ID and shaft. In addition, a “spring area groove” was designed behind the scraper lip to allow for proper spring-flex action and to accommodate thermal expansion during operation. Lastly, undercuts were machined at both ends of the bearing shell to anchor the snap-in ETX scraper seals. Since the scraper lips are zero-clearance on the shaft, the interference fit prevents cheese residue from migrating beneath the seal as it scrapes the shaft surface.

At first glance, Black Racer linear bearings wipe the floor with linear ball bearings. However, linear ball bearings provide the lowest coefficient of friction for mechanical bearings – only surpassed by air bearings. Linear ball bearings are more compliant than sleeve bearings, thus they are more forgiving in applications where shaft parallelism is not exact. Linear ball bearings offer more self-alignment capability than sleeve bearings. Although Black Racer bearings are direct drop-in re­placements for inch linear ball bearings, you should call LM76 to ensure your application is a good candidate.

Application Story – FDA/Washdown System Excels with Special Linear Motion Shaft Assembly from LM76!

Linear Motion - Application Story - Dairy

LM76

E. Longmeadow, MA – — Linear Motion – Application Story – 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?

First, we decided to forgo the original bearing system that used 440c stainless linear ball bearings running on 440c hardened shafting. After reviewing loads and speeds we determined that our stainless FDA Compliant, self-lubricating linear bearings would do the job. By choosing sliding friction bearings, we were able to switch the less corrosion resistant 440c with a better 316 stainless shafting while eliminating greasing of the linear ball bearings. To increase shaft hardness, corrosion resistance and decrease “Stick/Slip” of the sliding bearings, we applied an Armoloy coating. This coating raises the shaft hardness from Rb25 to Rc78. Additionally, both the 316 stainless and the coating are FDA compliant. Along with enhanced hardness, corrosion resistance and FDA compliance, this coating has an inherent lubricity that aids in lowering “Stick/Slip”. “Stick/Slip” is a condition inherent in sliding linear bear¬ings. It takes a greater force to move a sleeve bearing linear system from static position than it does to maintain dynamic motion. Thus any assistance in lowering this value is meaningful. Now that we had the correct shafting, we turned our attention to the aluminum shaft support Here we made 2 design decisions:

1. We applied a ceramic coating to the aluminum “T” support. This coating is FDA compliant, is file hard (resists scratching) and is highly corrosion resistant.

2. To enhance system flushing to remove trapped product that could produce harmful bacteria, we segmented the support system to allow for proper evacuation of all washdown solutions and debris.
