Thin Section Ball Bearings – Sealed-Four-Point Contact (Type X) JHA-JG Series
The four-point contact ball bearing, capable of accommodating radial, axial, and moment loads, delivers high rigidity. Building on open-type constant-section bearings, its design integrates seal rings on both sides, optimizing lubrication, minimizing required grease volume, and providing effective dust protection.
Width Range: From 1/4″ (6.35mm) to 1″(25.4mm)
The four-point contact ball bearing is capable of accommodating three distinct load types (radial load, axial load, and moment [torque] load), thereby delivering enhanced rigidity. Building upon the design of open-type constant-section bearings, this configuration integrates seal rings onto both sides of the bearing unit. This structural innovation not only optimizes lubrication performance but also minimizes the required grease fill quantity. Additionally, the seal rings provide effective dust ingress protection, further enhancing operational reliability.
