Plastic ball transfer units
Plastic ball transfer units have a housing and flange made of tough Polyoxymethylene (POM). They offer exceptional resistance to water, including salt water, and chemical substances. Polyoxymethylene is also simply called POM or sometimes referred to as acetal, polyacetal or polyformaldehyde plastic. It is an engineering thermoplastic and plastic ball transfer units made from POM are characterized by their excellent dimensional stability and low levels of friction.
Neither magnetic nor conductive, SPP type plastic ball transfer units have a working temperature range of 0 - 60°c. They are available in various versions and can be manufactured with an optional insert for a fixing ring to comply with DIN 471.
