TRUSCO Plastic Bearing PEEK Outer Diameter 8 Inner Diameter 3 TCP0803 1 pc

Catalog number: TCP0803 Features: ● Made of PEEK resin, it has excellent self-lubrication, impact resistance, fatigue resistance, heat resistance, wear resistance, and chemical resistance. ● The dimensional accuracy of the inner and outer diameters is ±0.02 mm. The bearing is manufactured with an internal clearance that takes into account the expansion and contraction of the resin due to temperature changes and the dimensional changes due to fitting with the shaft and housing. ● Can be used without grease or lubricating oil. ● Helps reduce the weight of robots and machinery. ● Recommended rotation speed in air is 800 RPM or less. ● Alumina balls are resistant to most chemicals. ● Greaseless and lubricating oil-free, making it ideal for use in clean environments. Applications: ● As rollers for transport equipment, guide rollers, and various rollers.
