PEEK rolling bearing

PEEK rolling bearing

PEEK rolling bearings are widely used in aseptic cold filling equipment. They are environmentally friendly, non-toxic, and comply with FDA food safety certification. They feature low noise, self-lubrication without oil contamination, long service life, rust-free operation, and stable performance. PEEK rolling bearings are expected to see extensive use in aseptic cold filling equipment in the future.

PEEK Properties

1

Eco-friendly and non-toxic. PEEK itself is environmentally friendly, non-toxic, and has passed FDA certification. It can be used for food contact with no time limitation on contact.

2

Low moisture absorption and hydrolysis resistance. It can work long-term in water and steam environments.

3

Excellent wear resistance. PEEK and its composites have leading wear resistance among plastics, three times that of copper alloys.

4

Corrosion resistance. Food processing and packaging equipment is designed for self-cleaning to ensure food quality and safety. Cleaning solutions are typically composed of acids and chlorine. PEEK has an amazingly stable chemical structure with excellent corrosion resistance against various organic and inorganic solutions, even at high temperatures. It solves the problem of metals and ordinary plastics being unable to withstand corrosion long-term.

5

Self-lubrication. It can operate stably for long periods without the need for oil lubrication. This avoids the use of metal parts that require oil lubrication, preventing contamination of packaging machines and food products. At the same time, the appearance of packaging machines remains cleaner.

6

Easy to form. PEEK has excellent processing and forming characteristics. It can be processed using injection molding, machining, milling, drilling, tapping, NC, CNC, and other processes to conveniently manufacture various complex shaped parts according to customer drawings or samples.

7

High temperature resistance. Packaging machines and food products are typically sterilized through high temperatures and lasers. PEEK has a continuous use temperature up to 260°C. It maintains good mechanical strength even at 300°C and can be heated in hot air ovens, autoclaves, contact heaters, or microwave ovens. Therefore, PEEK parts can withstand repeated sterilization, including 200°C autoclave sterilization, 143°C flash sterilization, γ-ray sterilization, and ethylene oxide sterilization. It does not lose mechanical properties and maintains excellent stress cracking resistance.

Thanks to PEEK’s excellent characteristic advantages such as wear resistance, high temperature resistance, high strength, and self-lubrication, we can ensure continuous long-term use of equipment components, avoiding equipment downtime caused by part replacement.
