Precision Acid & Alkali Resistant Plastic Bearings

POM/PA plastic bearings (precision plastic bearings):
POM and PA materials have good mechanical strength and wear resistance, and are suitable for making relatively precise
plastic bearings. Their good self-lubricating properties and low friction coefficient help maintain the transmission of plastic bearings.
Based on the advantages of the system, it can be applied to precision and higher speed operations. Among them, POM plastic bearings
are the most widely used among all plastic bearings. Generally, the inner and outer ball materials are POM or
PA, and the cage is made of glass fiber reinforced nylon 66 (GRPA66-25). The balls are glass
balls, stainless steel balls or ceramic balls. This kind of bearing performs well in alkaline environment but is not suitable
for operation in acidic corrosive environment.

HDPE/PP/UPE (UHMW-PE) plastic bearings (acid and alkali resistant plastic bearings):
HDPE, PP, and UPE materials have been proven to be used in relatively weak acid-base cross-environments, so
they are suitable for most acids, alkalis, and salts , solvent, oil, gas and seawater corrosive environment. It has the oil-free self-lubricating, anti-magnetic and electrical insulation properties of
general plastic bearings, but its mechanical strength is low and
it is easy to deform, so it is not suitable for larger loads and higher speeds. In comparison, UPE materials
have better strength, low friction characteristics and low temperature application characteristics (as low as -150 degrees C).
Generally, the inner and outer ring materials are HDPE, PP or UPE, and the cage materials are HDPE, PP
