Products and services
- Metal-Polymer Composite Bushings Steel-backed bronze bushings with PTFE, PEEK, POM, PVDF or fluoropolymer bearing layers designed for maintenance-free operation, low friction, and resistance to wear in automotive, hydraulic, and industrial applications. Supports rotary, linear, and oscillating motions.
- Bi-Metallic Composite Bushings Steel-backed bushings with leaded or lead-free bronze bearing surfaces featuring oil pockets, grooves, and holes for oil-lubricated high-load applications. Includes CSB-820 lead-free and CSB-800 leaded bronze variants.
- Bronze Wrapped Bushings Cold-formed homogeneous CuSn8 bronze wrapped bushings with diamond-shaped lubrication indents (CSB-090), graphite plugs (CSB-09G), or through holes (CSB-T90) for construction, agricultural, and general machinery applications.
- Metallic Self-Lubricating Bushings Steel-backed bushings with cast bronze or sintered metallic bearing layers containing dispersed solid lubricants such as graphite and MoS2, providing maintenance-free operation across temperature ranges from -200C to +600C in vacuum, radiation, and severe environments.
- Non-Metallic Self-Lubricating Bushings Plastic compound bushings (CSB-EPB series) made from injection molded engineering plastic with intensifiers and lubricants, and filament wound composite bearings (CSB-CR series) with glass fiber, epoxy resin, and PTFE wound fiber for dry operation in office machinery, fitness equipment, textile machinery, and similar applications.
- Specialty Bushings and Wear Components Custom-engineered bearing solutions including steering rack bushings, escalator rotary chain components (CSB-PEC series), solid bronze turned bushings, spherical plain bushings, hardened steel bushings (C45/100Cr6), and compressor swash plates for automotive and heavy equipment applications.
