OPW Downfeed Left Hand Counterbalance Swivels

Description

OPW Style 58 3000 series manual swivel joints are machined and have micro-finished grooves that provide for minimal seal wear. Body and tail sections are locked together by a double row of ball bearings. Carbon steel swivels have hardened races to maximize load-carrying capability. All OPW swivels are pre-lubricated at the factory. Protective inner O-ring seal prevents product from entering bearing chamber. Available in 3 in & 4 in. sizes. Call a JME Sales Specialist at 800-333-3331 for details on other versions based on end connections, material, sizes, or seal type.
