CHF's GE..ES series of stainless steel spherical plain bearings are high-performance enhanced models based on the standard GE..E series. This series is specifically developed for demanding applications requiring extremely low friction, lifetime maintenance-free operation, and extremely high reliability, and integrates PTFE fiber composite materials with a high-strength stainless steel matrix. As a professional stainless steel bearing manufacturer, CHF provides ideal bearing solutions for high-end industrial markets in Europe and America, particularly in aerospace, precision hydraulics, medical equipment, and semiconductor manufacturing equipment, under conditions requiring heavy loads, low-speed oscillation, oil-free environments, and ultra-high cleanliness.
Key Technical Features
Three-Layer Composite Gasket: Utilizes a three-layer composite structure of PTFE fiber, epoxy resin, and metal mesh lining. The gasket thickness ranges from 0.5-1.0 mm, significantly improving wear life.
Low Friction and Wear Resistance: Dynamic friction coefficient ≤0.03, static friction coefficient ≤0.05, PV value up to 3.0 N/mm²·m/s.
High Load-Bearing Stainless Steel Matrix: Both the outer and inner spherical rings are made of AISI 440C stainless steel, subjected to ultra-deep cryogenic treatment (-196°C) and secondary tempering, improving dimensional stability and fatigue resistance by 40%.
