JA030CP0 ultra thin wall deep groove ball bearing keeps JA‑series equal thin cross‑section at medium bore size. Open‑type structure facilitates grease re‑lubrication. It works well under radial‑dominated conditions with permissible moderate axial loads. Commonly applied for miniaturized automation units,optical rotary parts and small precision instrument assemblies.

C-type deep groove ball bearings - JA series (double-sided sealing) feature a standard deep-groove raceway design with integrated contact rubber seals on both sides, providing superior protection against dust, moisture, and contaminants while maintaining moderate speed capability. Available in double-sealed configurations only, with bore diameters ranging from 8mm to 180mm. These bearings deliver effective contamination protection, grease retention, maintenance-free operation, and reliable long-term performance, making them ideal for automotive components, agricultural equipment, conveyor rollers, industrial fans, electric motors, and general machinery applications where reliable sealing is required.
