JHA15XL0 ultra thin wall four point contact ball bearing adopts JHA series constant slim cross‑section and double‑sealed construction. Made of high‑grade chrome bearing steel with nylon cage, it handles radial, bidirectional axial and moment loads simultaneously. Super‑finished gothic‑arch raceway delivers high rigidity and low‑friction stable rotation. Suitable for compact positioning turntables,optical inspection equipment and light‑duty automation rotary components subjected to composite loads.

X-type four-point contact ball bearings - JHA series (double-sided sealing) feature a four-point contact raceway design with integrated non-contact rubber seals on both sides, supporting bidirectional axial loads while providing effective dust protection and maintaining low friction torque. Available in double-sealed configurations only, with bore diameters ranging from 20mm to 200mm. These bearings deliver compact design, high axial rigidity, low rotational resistance, and maintenance-free operation with contamination protection, making them ideal for industrial robot joints, slewing rings in clean environments, packaging machinery, medical equipment, and precision automation systems where sealing is required without sacrificing speed or efficiency.
