Wear factor (K) is an indication of a materials resistance to wear as a function of the volume of material lost, force (load) and velocity at the wear interface and time. It is often determined using a "thrust washer" wear testing apparatus per ASTM D3702 in which a molded plastic specimen is rotated against a substrate thrust washer under set pressure and velocity conditions.

A wear factor is calculated with the equation W=K*F*V*T. In this equation W is wear volume (in3), K is wear factor (in3 min/ft lb hr)10-10, F is force (lb), V is velocity (ft/min), and T is elapsed time (hr).

A material with a lower wear factor (K) has greater resistance to wear and these values are useful for material comparison purposes.

Comparing competitive data note

  • RTP Company reports Wear Factors per unit Force (KF) with units of (in3 min/ft lb hr)10-10. This is the industry standard way to calculate and report Wear Factor. Some suppliers report Wear Factors per unit Pressure (KP) with units of (in5 min/ft lb hr)10-10. This value is arrived at by dividing the KF by the contact surface of the test specimen (0.35 in2). As result of this reporting discrepency, RTP Company's Wear Factor values appear to be significantly higher. For example a KP of 3 (in5 min/ft lb hr)10-10 would be equal to KF of 3/0.35 = 8.57 (in3 min/ft lb hr)10-10.
