52217 Bearing Structural Features & Performance Benefits
High Load Capacity: The bearing's optimized geometry and chrome steel construction enable it to handle substantial axial dynamic loads up to 21,938 lbf and axial static loads up to 61,875 lbf, making it ideal for heavy thrust applications.
Precision Engineering: With tight dimensional tolerances on bore diameter (-0.015mm to 0) and outside diameter (-0.025mm to 0), this bearing ensures precise positioning and smooth operation in precision machinery.
Durability & Corrosion Resistance: The stainless steel cage provides excellent corrosion resistance and maintains structural integrity at the limiting speed of 2,200 rpm, while the wide temperature range (-30° to 110°C) ensures reliable performance across various operating conditions.
Compact Design: With a width of 55 mm and optimized chamfer dimensions (1 mm), this bearing offers space-efficient solutions without compromising on load-bearing capability.
