Washer is used between connecting part and nut, as a spacer to protect surface of the connecting part from being worn by the nut, and to reduce loosening or separation due to vibration caused during operation.
PEEK roller bearings use PEEK components with zirconia ceramic balls for oil-free operation, wear resistance, chemical resistance, high-temperature performance, and reduced wear caused by metal-to-metal contact.
Depending on equipment conditions and operating temperature requirements, the inner and outer rings and retainer can be made of PEEK or PTFE, while the balls are made of zirconia.

Advantages of Plastic Roller Bearings
PEEK roller bearings combine engineering plastic inner and outer rings and retainers with zirconia ceramic balls. They can operate without oil while meeting wear-resistance, chemical-resistance, and high-temperature requirements.
Oil-free operation
(Suitable for equipment where lubricants are inconvenient or prohibited.)
Reduced metal-to-metal wear
(Reduces wear caused by direct friction between metal components.)
Wear and chemical resistance
(Suitable for acidic, alkaline, and chemical media environments.)
High-temperature material options
(PEEK and PTFE can be selected according to temperature and environmental requirements.)
Common Material Selection Scenarios: Precision, High-Temperature & Corrosive Environments
High-Strength and Precision Acid/Alkali Environments
PEEK offers excellent dimensional stability, strength, corrosion resistance, and high-temperature performance, making it particularly suitable for acidic and alkaline environments requiring high strength and precision.
High-Temperature and Broad Corrosion-Resistant Environments
PTFE is suitable for a wide range of corrosive environments and long-term operating temperatures up to 260°C.
Non-Metallic Ball Requirements
Zirconia balls can be combined with PEEK or PTFE inner and outer rings and retainers.
※ Actual materials and bearing specifications must be comprehensively evaluated according to load, rotational speed, temperature, media, and operating environment.
