Q&A How do plastic bearings compare to standard metal bearings?

May 8, 2014

Plastic Bearings vs MetalIt is a question that is still widely debated ― how do plastic and metal bearing compare?   In some industries, plastic is regarded as a premium bearing material, while in others there is a prevailing misconception that plastic is inferior to metal.  We decided to compare the two by looking at a few of the key factors that determine bearing performance ― namely maintenance, durability and service life.  Here’s what we discovered:

Q&A - How can I measure the performance of plane bearings?

April 8, 2014

Calculating PV for Plane BearingsTo predict the performance of plastic plane bearings, two critical elements must be considered – Pressure (P) and Velocity (V).  Here’s a quick review of the formula we use:

P equals the load placed on a bearing assembly
V is the surface speed (in feet per minute) at which an object moves
PV is the combined effect of the pressure of the object as it moves against the bearing surface.
