JA020XP0 ultra thin wall four point contact ball bearing belongs to JA‑XP0 Reali‑Slim thin‑section bearing family. Manufactured from premium 52100 chrome bearing steel and fitted with nylon cage. This open‑type Type‑X four‑point contact bearing can bear radial, bidirectional axial and moment loads at the same time. Open‑type structure facilitates grease re‑lubrication. Constant slim equal cross‑section saves installation space and reduces overall weight. Widely applied in optical turntables, compact rotary modules, automation equipment and precision light‑load machinery with strict space‑limitation requirements.

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.
