Overview

This ball caster kit includes a two-part black ABS housing, a 1″ diameter POM (also know as acetal or by the brand name Delrin) plastic ball, and three ABS rollers. When assembled, the ball caster is capable of rolling in any direction with low friction, making it suitable for use as a third contact point for wheeled, differential-drive robots weighing up to around ten pounds.

The base piece of the housing has holes for three #4 or M3 mounting screws (not included) and slots for the three rollers. The second part of the housing snaps into the base piece to secure the ball and rollers. The assembled ball caster has an overall height of 1.1″ (29 mm).

This ball caster is also available with ball bearings instead of plastic rollers for smoother performance.
