JA025XP0 ultra thin wall four point contact ball bearing adopts JA 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 - JA series (double-sided sealing) feature a four-point contact raceway design with integrated contact rubber seals on both sides, supporting bidirectional axial loads while providing superior protection against dust, moisture, and contaminants in demanding environments. Available in double-sealed configurations only, with bore diameters ranging from 20mm to 220mm. These bearings deliver compact design, high axial rigidity, excellent contamination protection, reliable grease retention, and maintenance-free operation, making them ideal for construction equipment slewing rings, agricultural machinery turntables, material handling systems, port machinery, and heavy-duty industrial applications where reliable sealing is essential.
