Minuteman Self Lubricating Linear Bearings
 

• Coefficient of Friction: .0015 - .015

• Running Clearance: Zero Clearance

• Operation: Noisy and produces resonance

• Motion: Linear Only

• Fails in applications which feature:
  contamination, washdown, shock, rapid oscillation, high loads

• Shafting: RC60 Hardened Shafting ONLY

• Magnetic

• Misaligned Shafting: Works Well

• Moment Loading: Works Well

• Mechanical Failure Mode: Extreme - balls can fall out of the housing - shafting can become grooved

• Chemical Resistance: Questionable
  
  Note: Linear ball bearings require a stroke that is 1.5 x's the length of the bearing. Strokes less than this lead to failures because you are using the same balls all the time. They do not have an opportunity to fully recirculate and pick-up more lubricant. Thus you end-up running steel on steel. Therefore, rapid oscillation is highly damaging to both bearing and shaft.
   

• Coefficient of Friction: .09 - .15

• Running Clearance: + .001

• Operation: Quiet & Smooth

• Motion: Linear & Rotary

• Thrives in applications which feature: contamination, washdown, shock, rapid oscillation, high loads

• Shafting: Hardened & Soft 300 Series Stainless Steel

• Non-Magnetic

• Misaligned Shafting: Problematic

• Moment Loading: Problematic -
  particularly in Z axis ( vertical operation)

• Failure Mode: Mild - increased running clearance due to wear - no loss of mechanical components

• Chemical Resistance:
  EXCELLENT
