IKO GE50ES-2RS Spherical Plain Bearing Technical Specification
The IKO GE50ES-2RS is a high-performance double-sealed radial spherical plain bearing designed for self-aligning motion, heavy combined radial and axial loads, and misalignment compensation. Widely used for industrial pivot joints and linkage systems, this maintenance-friendly bearing delivers superior durability in harsh, low-to-medium speed operating environments.
Precision Dimension Parameters: Bore diameter d=50 mm, outer diameter D=75 mm, overall width B=35 mm, inner sliding width C=28 mm, maximum tilt angle 6°, minimum chamfer r=1.0 mm. It adopts standard P0 tolerance grade per ISO 12240 industrial standards, with standardized mounting dimensions for universal equipment compatibility.
Professional Material Configuration: Inner and outer rings are forged from AISI 52100 (100Cr6) bearing steel, heat-treated to 60–64 HRC, featuring exceptional wear resistance, high static load capacity and stable dimensional tolerance. The sliding contact surface undergoes special phosphating treatment for anti-friction and anti-corrosion performance. It is equipped with durable rubber 2RS double-lip seals to block dust, moisture and contaminants.
Core Manufacturing Technology: Adopts integrated hot forging to optimize metal grain structure, followed by precision turning and fine boring. Standardized quenching and tempering eliminate residual stress. High-precision grinding and superfinishing on spherical sliding surfaces ensure ultra-low friction coefficient and smooth oscillating motion, greatly improving operational stability.
Standard Service Life: Calculated in accordance with ISO 281 bearing life criteria. Under standard clean lubrication and rated load conditions, the nominal L10 service life reaches 12,000 operating hours. Key life-affecting factors include frequent misalignment, lubricant failure, environmental contamination and overload operation.
Industry Applications: Ideal for construction machinery, hydraulic equipment, automotive suspension systems, agricultural machinery and automated industrial linkages. Its outstanding self-aligning capability and heavy-load resistance perfectly adapt to pivot and oscillating working scenarios with inevitable shaft misalignment.
Maintenance Standards: Implement comprehensive inspection every 800–1000 operating hours. Use extreme-pressure lithium grease with a filling volume of 30%–40% of internal cavity. Keep mounting surfaces clean and dust-free. Inspect seal integrity, operating friction and abnormal jitter; replace lubricant immediately if contamination occurs.
