Key Performance Advantages:
High Load Capacity (300 Series): As part of the heavy-duty 300 series, the UC326G RICH features a much larger cross-section and rolling elements than standard inserts. This allows it to support massive radial loads and withstand heavy shock impacts in industrial environments.
Extended Inner Ring Stability: The 135 mm wide inner ring provides a substantial contact area with the shaft. This ensures maximum stability and reduces the risk of shaft tilting or fretting under extreme torque and heavy-duty operation.
Self-Aligning Spherical Design: The rounded outer ring allows the bearing to compensate for static misalignment of the shaft within its housing. This prevents internal stress and ensures smooth rotation even if the mounting surfaces are not perfectly aligned.
Reinforced Protection System: Equipped with double-sided lip seals shielded by metal plates. This configuration is specifically designed to keep high-pressure grease in while blocking the entry of heavy dust, grit, and moisture common in mining or outdoor industrial sites.
Large-Scale Precision: Despite its 22.275 kg weight, the bearing is engineered for precise rotation, ensuring that large-diameter 130 mm shafts operate with minimal friction and maximum drivetrain efficiency.
Transparency Note: This product is manufactured under the RICH brand. The code UC326G is used for identification purposes.
