KG140XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry creates four contact points between the balls and raceways, enabling a single bearing to handle combined radial, axial, and moment loads efficiently. This eliminates the need for multiple bearing arrangements, simplifying system design.
Thin-Section Construction: With identical 1" cross-sections across all bore sizes in the series, the KG140XP0 provides maximum load capacity within minimal space. The compact design contributes to reduced system weight and size while maintaining structural integrity.
Premium Material Composition: Constructed from chrome steel rings and balls with a brass cage, the bearing offers excellent durability and reliable operation under heavy loads. The brass cage ensures smooth operation at moderate speeds.
High Load Capacity: With a radial dynamic load rating of 14,404 lbf and axial dynamic load rating of 23,410 lbf, this bearing delivers exceptional performance in demanding applications. The static load moment capacity of 184,700 lbf provides significant safety margin against deformation.
Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (0.0000 – 0.0005"), ensuring consistent performance and reliable operation in precision applications.
