JU040XP0 ultra thin wall four point contact ball bearing belongs to JU‑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 - JU series (double-sided sealing) feature a four-point contact raceway design with integrated heavy-duty contact rubber seals on both sides, supporting bidirectional axial loads while providing maximum protection against dust, water splashes, and contaminants in the harshest operating environments. Available in double-sealed configurations only, with bore diameters ranging from 30mm to 300mm. These bearings deliver compact design, high axial rigidity, superior sealing effectiveness, excellent moisture resistance, reliable grease retention, and maintenance-free operation in extreme conditions, making them ideal for heavy construction machinery slewing rings, offshore equipment, agricultural machinery, food processing equipment with washdown requirements, port material handling systems, and heavy-duty industrial applications where maximum environmental protection is essential.
