Self-Aligning Spherical Roller Bearings 205215 - High Performance from China Suppliers and Factory

Structural Features of Spherical Roller Bearings

Our spherical roller bearings feature two rows of symmetrical spherical rollers along with a common outer spherical raceway. Designed with an innovative inner ring that contains two raceways, these bearings are tilted at a specific angle relative to the bearing axis, enhancing their performance.

Known for their remarkable self-aligning capabilities, our spherical roller bearings are ideal for applications where shaft misalignment may occur. Even in cases of bending or installation errors that create an angular deviation between the inner and outer ring axes (typically within 1°-2.5°), these bearings maintain optimal functionality. As a leading China supplier and factory, we ensure the highest quality standards for our products.

Performance Parameters

Load Capacity

Withstands large radial loads and bidirectional axial loads, adapting to heavy load and impact conditions. Cr rated dynamic load: 29,300N, Cor rated static load: 26,900N.

Limiting Speed

Limiting speeds vary by configuration: reaches up to 6,300 r/min with grease lubrication and up to 8,200 r/min with oil lubrication.

Application Fields

Industrial Machinery

Widely used in rock drills, corrosion-resistant pumps, ceramic building materials processing equipment, mixers, compression molding machines, and other heavy equipment.

Automotive Field

Applied to vital power transmission, support mechanisms, and critical automotive assemblies.

Other Industries

Forestry machinery, chemical reaction equipment, color printing machines, mining analyzers, coating, and dust removal machinery.

Common Model Suffixes and Meanings

W33

Indicates lubrication grooves and three lubrication holes strategically placed on the outer ring of the bearing.

K

Denotes a tapered inner bore (1:12 taper standard). E.g., 21304K identifies a tapered bore spherical roller bearing.

CA / CC

CA: Precision machined one-piece brass solid cage.
CC: Two-piece stamped steel window-type cage with guide ring.

Features

Self-Aligning Function

Accommodates angular misalignment and shaft deflection without increasing friction or operational temperature.

High Load Capacity

Engineered to support heavy radial and axial loads simultaneously in both directions for demanding heavy-duty operations.

Low Friction & Extended Life

Advanced relubrication features maximize wear resistance, lower running temperatures, and prolong equipment uptime.

Frequently Asked Questions (FAQ)

1. What are the key advantages of self-aligning spherical roller bearings?

Spherical roller bearings are designed to accommodate angular misalignment and shaft deflection without increasing internal friction or temperature, ensuring high durability under heavy radial and bidirectional axial loads.

2. What is the difference between CA and CC cage designs?

The "CA" suffix features a precision-machined solid brass cage and retaining flanges for high strength. The "CC" suffix denotes a stamped steel window-type cage with a floating guide ring, offering reduced friction and higher operational speeds.

3. What does the "W33" suffix signify?

The W33 suffix indicates that the bearing outer ring includes an annular lubrication groove and three lubrication holes, enabling simple and efficient periodic relubrication directly into the raceway.

4. How does lubrication affect the limiting speed of 21304 bearings?

With standard grease lubrication, the limiting speed is 6,300 r/min. When using oil lubrication, heat dissipation and friction reduction improve, allowing limiting speeds up to 8,200 r/min.

5. Can I order custom packaging or OEM branding?

Yes, JITO offers comprehensive OEM manufacturing services along with customizable industrial packaging, including pallets, wooden crates, and commercial individual boxes.

6. What precision grades and clearance classes are available?

These bearings can be manufactured in precision grades P0, P6, P5, P4, and P2, with radial internal clearances available across C0 (standard), C2, C3, C4, and C5.
