The 21315 Spherical Roller Bearing is a heavy-duty, self-aligning rolling bearing widely used in industrial heavy-load scenarios. It has a standard inner diameter of 75mm, outer diameter of 160mm, and width of 37mm. Designed with two rows of symmetric spherical rollers, it adapts to misalignment and shaft deflection, excelling in handling high radial loads and moderate bidirectional axial loads, making it ideal for harsh, high-load mechanical systems.
Dual rows of spherical rollers distribute loads evenly, enabling it to bear extremely high radial loads and moderate axial loads, suitable for heavy-duty equipment.
Compensates for significant angular (up to 2-3°) and parallel shaft misalignment, avoiding wear from installation errors or equipment deformation.
Made of high-strength alloy steel with optimized heat treatment, it operates stably under high temperatures (up to 150°C) and severe vibration.
Precision-machined raceways and rollers reduce friction; advanced sealing options prevent contamination, extending service life in harsh environments.
Essential for key components like crushers, ball mills, grinding machines, and conveyor system rollers, enduring extreme radial loads, continuous operation, and dusty, abrasive working environments.
Widely used in large-scale high-power motors, industrial ventilation fans, centrifugal blowers, and air compressors, adapting to high-speed rotation, load fluctuations, and long-term continuous operation requirements.
Critical for rolling mill stands, blast furnace tilting mechanisms, continuous casting machines, and steel belt conveyors, withstanding high temperatures, heavy impact loads, and harsh industrial atmospheres.
Applied in excavator slewing rings, crane main shafts, concrete mixer trucks, and marine propulsion systems, resisting corrosion, shock loads, and complex operational stresses in outdoor or marine environments.
