Precision CNC Turned Nylon and POM Bushings and Spacers

Plastic bushings are turned from extruded rod or tube. The outside diameter and bore are finished in the same chucking to keep them concentric, and the part is cut off cleanly to avoid a pip on the face. Flanged and slotted designs get their features from live tooling. Tolerances are cut with knowledge of how much the material will spring back once released from the chuck.

POM is preferred for precise bushings because it barely absorbs water and stays dimensionally stable. Nylon PA6 or PA66 is tougher under impact and runs well against steel, but swells up to a few percent in humid conditions, so bore clearance must allow for it. Oil-filled or MoS2 Nylon grades reduce friction further. ABS is used for non-bearing spacers and covers where cost and color matter more than wear.

Bores are checked with pin gauges and outside diameters with micrometers at stable room temperature. For press-fit bushings we also verify interference against your housing size. Critical dimensions are 100% inspected before shipment under our ISO 9001 system. Common applications include linkage bushings, pulley sleeves, robot joint spacers, motorcycle suspension wear parts and medical device guides.
