The CHF GE..ES-2RS series stainless steel double-sealed self-lubricating radial spherical plain bearings are enhanced versions of the GE..ES series, featuring integrated contact seals on both sides (2RS). This series is designed for demanding applications involving highly polluted environments, dusty conditions, liquid splashes, and absolute prevention of internal lubricant loss. Combining the corrosion resistance of stainless steel, the maintenance-free self-lubrication of PTFE, and the reliable protection of double seals, it provides high-end industrial customers in Europe and America, particularly in agricultural machinery, construction engineering, food processing, and heavy-duty outdoor equipment, with dustproof, corrosion-resistant, and maintenance-free heavy-duty spherical plain bearing solutions.
Key Technical Features
Sealing Performance Parameters: Dustproof rating up to IP6X, completely preventing dust intrusion; waterproof rating up to IPX7, able to withstand short-term immersion. The sealing lip contact force is precisely designed to achieve a balance between low frictional torque and high sealing reliability.
Anti-Loss Sealing Structure: The sealing ring is interference-fitted to the bearing outer ring via a metal skeleton and employs an anti-rotation design to ensure it will not fall off under strong vibration or impact.
High Load-Bearing PTFE Composite Liner: The inner ring has a glass fiber reinforced PTFE composite liner sintered on its spherical surface, with uniform thickness (0.8-1.2mm), a dry friction coefficient as low as 0.04, and a load-bearing capacity approximately 15% higher than the standard type.
Immediate Stainless Steel Material: Both inner and outer rings are made of AISI 440C stainless steel, undergoing a full-process heat treatment of vacuum quenching + deep cryogenic + low-temperature tempering, achieving a hardness of HRC 58-62, high fatigue strength, and excellent corrosion resistance.
