Sliding Velocity v

The sliding velocity for bushings and thrust washers results in:

Where
v	sliding velocity, m/s
d	bore diameter of bushing, mm
J	middle diameter of thrust washer, mm (Find dimension J in the product tables: [GLYCODUR^® F] or [GLYCODUR^® A])
f	angular frequency or rotational frequency, min^-1
ß	half turning angle in degrees (see - Drawing Turning Angle) 90° in case of rotational movement

– Drawing Turning Angle

A complete oscillation = 4ß: way from point 0 to 4

Sliding velocity factor c₂

Increasing sliding velocity will lead to increased heat generation in the sliding surface; the wear rate increases. Therefore, the velocity factor c₂ has to be considered when designing the bearing.
