PERFORMANCE RATINGS<br />
FOR <strong>LINEAR</strong> <strong>MOTION</strong><br />
Plane bearings are rated by their limiting PV, which is a<br />
combination of load over a given surface area and the velocity.<br />

20,000 (psi x ft./min.)<br />
or<br />
0.7 N/m 2 x m/s<br />
PV = The performance measurement of plane bearings<br />
PV = P x V where P = pressure (load) in psi (kgf/cm 2 )<br />
V = velocity (speed) in sfm (m/min.)<br />
NOTE: All three parameters must be met by an application for<br />
the bearing to perform properly.<br />
CANTILEVERED LOADS<br />
Binding of the carriage will occur<br />
if the 2:1 ratio for cantilevered<br />
loads and drive forces is exceeded.<br />
This principle is not load or force<br />
dependent. It is a product of the<br />
coeffi cient of frictions associated<br />
with plane bearings. Contact<br />
factory or website for additional<br />
information.<br />
