Bearings,as important components in contemporary mechanical equipment,mainly support the mechanical rotating body,which can reduce the friction coefficient during its movement and ensure its rotation accuracy.
UCPH bearing is a type of bearing unit. This bearing unit is also a combination of PH bearing housing and pillow block bearing. UCPH bearing seat is much higher than other types of bearing housing, mainly used in special installation environment. The bearing housing is mainly made of cast iron, and stainless steel and plastic materials are used less than cast iron. The pillow block bearing is the same with the other types of mounted bearings unit.
