Product Description

The 22320 Spherical Roller Bearing Product Overview

The 22320 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 100mm, outer diameter of 215mm, and width of 73mm. 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 22320 Spherical Roller Bearing Features

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 22320 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.

Frequently Asked Questions

What are the main dimensions of the 22320 Spherical Roller Bearing?

The 22320 Spherical Roller Bearing has a standard inner diameter (bore) of 100mm, an outer diameter of 215mm, and a width of 73mm.

How does the self-aligning feature of this bearing work?

It is designed with two rows of symmetric spherical rollers and a spherical outer ring raceway. This allows the bearing to compensate for angular shaft misalignment (up to 2-3°) and parallel misalignment automatically without causing excessive stress or wear.

What operating temperatures can the 22320 bearing withstand?

Constructed from high-strength alloy steel with optimized heat treatment, this bearing operates stably under high temperatures up to 150°C and maintains integrity under severe vibration environments.

In which industries is the 22320 Spherical Roller Bearing typically used?

It is widely used in heavy-duty machinery for industries such as mining and mineral processing (crushers, ball mills), metallurgy and steel mills (rolling mill stands), heavy industrial motors, fans, construction machinery, and marine propulsion systems.

Can this bearing support both radial and axial loads?

Yes, it is specifically designed to handle very high radial loads while simultaneously supporting moderate bidirectional axial loads, making it ideal for multi-directional stress applications.

How does the bearing prevent dust and contaminants from entering?

The bearing layout facilitates advanced sealing options and features precision-machined raceways, preventing dust, water, and debris from entering the internal components, which significantly extends its service life in harsh environments.
