JB020XP0 ultra thin wall four point contact ball bearing belongs to JB‑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 - 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.
