Product Description

The 22317 Spherical Roller Bearing Product Overview

The 22317 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 85mm, outer diameter of 180mm, and width of 60mm. 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.

The 22317 Spherical Roller Bearing feature

1. Exceptional Load Capacity 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.

2. Strong Self-Aligning Performance Compensates for significant angular (up to 2-3°) and parallel shaft misalignment, avoiding wear from installation errors or equipment deformation.

3. High-Temperature & Vibration Resistance Made of high-strength alloy steel with optimized heat treatment, it operates stably under high temperatures (up to 150°C) and severe vibration.

4. Long-Lasting Durability Precision-machined raceways and rollers reduce friction; advanced sealing options prevent contamination, extending service life in harsh environments.

The 22317 Bearings Applications

1. Mining & Mineral Processing Machinery 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.

2. Heavy-Duty Industrial Motors & Fans 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.

3. Metallurgical & Steel Industry Equipment 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.

4. Construction & Marine Engineering Machinery 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.
