Plastic bearings are NOT all created equal – The difference is in the Manufacturing Methods, Construction and Design.
We produce plastic radial ball bearings utilizing engineering polymers such as Acetal PP,PA66,POM, PEEK , PVDF and PBT. Bearings manufactured with these materials are suitable for a wide range applications including Food, Medical, Pool and Spa, Marine, Semi-Conductor, Business Equipment and Automotive. The bearings are produced by these materials can run in and around liquids, or can run dry without the worry of lubrication. Fitted with a non metallic ball, they become non-magnetic and desirable for MRI use. They are best suited for low loads and slow to moderate speeds.
The following materials available for specific uses:
- POM (Celcon? Acetal): Standard material for general purpose
- PEEK: Extreme performance, high temperature, and sterilizable
- PVDF (Kynar?, Solef?) Extreme chemical compatibility and mechanical performance, and sterilizable.
- PBT (Valox?) Chemical resistance, autoclavable, and gamma sterilizable. General mechanical performance
BEARING CONSTRUCTION
Standard plastic ball bearing has polymer rings and cages fitted with either 316 stainless or borosilicate glass balls. Deep groove construction that does not compromise in a true race groove depth and design. The result is longer life through lower friction.
For underwater applications, the plastic bearing features designing allows suspended particles to enter the bearing and flow through without clogging and locking up. This is achieved by the very nature of the rings and cage being made of plastic, the design and clearances of the cage, and race groove geometry. This proven technology was developed through its use in the Pool and Spa industry for over 30 years.
