A plastic radial ball bearing is used in outdoor applications, such as traffic signal control boxes, because it can run without lubrication, and will not rust. It can operate in environments with challenges of humidity, rain, snow, and hot or cold climates without lubrication failures or corrosion.
Critical design features: Acetal POM plastic races fitted with 316 stainless balls. Bearing construction features True Race Technology™ ball grooves, and full complement bearing construction for optimum load capability.
Additional reasons for use:
Lower friction: A plastic race bearing will naturally have a lower coefficient of friction than a metal to metal ball bearing.
A KMS bearing is designed to tolerate suspended particles without clogging. This reduces required maintenance on your product.
A KMS plastic bearing can be designed with special shapes or profiles to better suit your application. It will provide ease of assembly and improved life and performance of your product.
