The GRACO 178881 Bearing, Piston is a precision-engineered component designed for use within GRACO spray foam and fluid handling equipment. Its primary function is to support and guide the piston within the pump assembly, ensuring smooth operation and reducing wear. The material is not explicitly specified in available listings, but similar piston bearings in industrial pumps are commonly made from durable plastics such as Delrin or high-performance composites for longevity and low friction.

Key Features:
