PHSB Inch Joint Bearing
PHSB spherical plain bearings feature strong load-carrying capacity, self-aligning function and low friction characteristics, enabling low-speed swinging and angular tilting movements.
POSB Inch Joint Bearing
POSB spherical plain bearings are compact in size but can simultaneously withstand large radial loads and bidirectional axial loads. They feature a special PTFE inner lining for contact, offering excellent wear resistance and load capacity
CF Inch Joint Bearing
CF spherical plain bearings are usually made of carbon steel and undergo galvanization treatment. The inner ring is made of bearing steel and can reach a hardness of HRC57-61 after heat treatment, featuring both wear resistance and corrosion resistance
CM Inch Joint Bearing
CM spherical plain bearings are mostly two-piece designed rod end spherical plain bearings. The housing is usually made of galvanized carbon steel, and the inner ring is made of heat-treated bearing steel, which can withstand certain radial loads and relatively small axial loads
product highlights
High Precision Spherical Design
Spherical tolerance ±0.002", ensuring low friction (μ≤0.08) and long lifespan (>10,000 hours).
Self-aligning capability compensates for installation errors, enhancing system stability.
Self-Lubricating Technology
Uses PTFE fabric liner, eliminating the need for external lubrication and suitable for extreme environments (high temperature, vacuum, corrosion).
Friction coefficient reduced by 40% compared to traditional bearings, saving 15% energy.
High-Strength Materials
Bearing steel (GCr15) quenched and tempered, hardness HRC58-62, compressive strength ≥1,500MPa.
Stainless steel (316L) models resist salt spray corrosion, passing 1,000-hour neutral salt spray test.
Cryogenic Resistance
Special - treated models maintain 95% of mechanical properties at -196℃(liquid nitrogen environment), expanding applicability in LNG equipment and space cryogenic systems.
Application Scenarios
Mechanical Lathe Equipment

Materials and Processes
Bearing Steel (GCr15): High wear resistance, suitable for heavy loads (≥50MPa contact stress).
PTFE Liner: Self-lubricating, chemically inert, resistant to strong acids and alkalis.
Surface Treatments:
*Phosphating (3-5μm film) improves rust resistance.
*Nano-ceramic coating (Al₂O₃) reduces friction coefficient to 0.08.
• Standards: Complies with GB/T 304.1-2017 (Classification of Spherical Plain Bearings), ISO 9001:2015.
• Testing: Coordinate measuring machine (accuracy ±0.001mm), salt spray tester, life cycle tester.
• Traceability: Blockchain-based traceability system ensures batch pass rate ≥99.9%.
ISO 9001 certification is a widely recognized quality management system certification standard internationally, developed by the International Organization for Standardization (ISO). It aims to assist various organizations in establishing, implementing and continuously improving quality management systems to ensure that products or services meet the requirements of customers and relevant laws and regulations.Focus on process management: It requires organizations to identify, manage and optimize each process (such as design, production, service, etc.) necessary to achieve quality goals, and reduce errors and improve efficiency through standardized processes.
