JAF UC 211 High-Performance Insert Bearing | 55mm Bore Set Screw Locking | Heavy Duty Industrial Reliability
The JAF UC 211 Insert Bearing is engineered for demanding industrial environments, providing exceptional reliability and reduced downtime across critical rotating machinery. Featuring a robust spherical outer ring, this unit compensates for moderate static misalignment. The bearing utilizes high-grade, heat-treated steel races (typically SAE 52100) and precision-matched balls, ensuring superior fatigue life and high dynamic load carrying capacity (Cr). The deep groove ball raceway design is pre-lubricated with extreme pressure (EP) grease and protected by integrated triple-lip seals (R-type), effectively blocking contaminants like dust, moisture, and fine particles, making it ideal for dirty applications. It is secured via two standard 120° set screws, facilitating easy installation and secure shaft gripping, minimizing slippage even under vibration.
This 55mm bore insert bearing is the preferred choice for applications requiring constant uptime, such as bulk material handling, agricultural equipment, heavy-duty conveying systems, and textile machinery. By focusing on robust sealing and anti-rotation features, the JAF UC 211 drastically reduces the required maintenance interval compared to standard units. Investing in JAF ensures maximum efficiency, longevity, and adherence to ISO quality standards, providing predictable performance and lower total cost of ownership (TCO) throughout its operational lifecycle.
