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.
