Product Description
Steel-Bronze Bimetal Sliding Bushing (with internal oil grooves)
Cylindrical plain bearing bushing, bimetal composite, precision machined with internal serpentine oil grooves
Construction machinery, hydraulic cylinders, automotive chassis, gearboxes, heavy-duty industrial equipment
Core Features
Bimetal composite construction: steel shell provides high structural strength, bronze inner layer delivers excellent wear resistance and anti-seizure property.
Built-in serpentine oil grooves: stores lubricant and forms uniform oil film, reduces friction and extends service life.
Good conformability and embedability, tolerates minor shaft misalignment and foreign particle contamination.
Wide application for heavy-load rotary & oscillating motion under oil or grease lubrication.
OEM & ODM available, custom sizes and groove patterns supported.
Typical Application Fields
Excavators, loaders, hydraulic equipment, truck chassis, gear boxes, agricultural machinery, injection molding machines, general heavy machinery.
