-
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.
