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

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
