Spherical roller bearing — model 21313W33 (part of the 21310–21315 CA family) Why you need this bearing Supports heavy radial loads while tolerating shaft misalignment to reduce wear and unscheduled downtime in demanding equipment. Self-aligning design protects gearboxes, shafts, and housings when shaft deflection or misalignment occurs. Precision bearing-steel construction provides durable, stable performance across variable operating conditions. Key attributes Model: 21313W33 Family: 21310–21315 CA spherical roller bearings Type: Self-aligning spherical roller bearing Material: Bearing steel components Compatibility: Designed to fit equipment specified for the 21310–21315 CA family and standard mounting arrangements and housings Color: approximate How this solves common problems Misalignment: The self-aligning geometry compensates for shaft deflection and mounting errors, preventing localized stress and premature failure. Heavy radial loads: Robust roller design carries large radial forces reliably, protecting connected components under continuous or shock loading. Variable conditions: Hardened bearing steel and proven design maintain performance under vibration, temperature changes, and intermittent duty. Practical applications (real-world scenarios) Conveyor systems experiencing misalignment and dynamic loading where consistent rotation and reduced maintenance are required. Industrial gearboxes, presses, and mixers that operate under heavy radial loads and need bearings that protect shafts and gears. Construction and agricultural machinery subject to vibration, impact, and variable shaft alignment. Installation and maintenance notes Fits standard housings and mounting arrangements for the 21310–21315 CA family; confirm fitment against your equipment’s spec sheet before installation. Ensure correct lubrication and follow the manufacturer’s recommended lubrication intervals. Observe specified mounting torque, axial clearance, and installation procedures in the technical documentation to achieve rated service life. Color is approximate and may vary. Ordering and compatibility tip Specify model 21313W33 when replacing or stocking bearings for equipment using the 21310–21315 CA family to ensure direct compatibility with standard mounts and housings.
