JB025XP0 ultra thin wall four point contact ball bearing adopts JB series constant slim cross‑section and open‑type 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 - JB series (double-sided sealing) feature a four-point contact raceway design with integrated light-contact rubber seals on both sides, supporting bidirectional axial loads while balancing sealing effectiveness with low friction for moderate speed applications. Available in double-sealed configurations only, with bore diameters ranging from 15mm to 200mm. These bearings deliver compact design, high axial rigidity, moderate contamination protection, low torque operation, and maintenance-free performance, making them ideal for packaging machinery, light-duty slewing rings, automated assembly equipment, textile machinery, and precision indexing devices where moderate sealing and smooth rotation are required.
