SKF 21307 CC/C2 Spherical Roller Bearing - High Precision with Close Tolerance

bearing Spherical roller bearing

Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. They can be used in a modular system, including housings, sleeves and nuts.

Accommodate misalignment

High load carrying capacity

Low friction and long service life

Increased wear resistance

Installation Method and Usage Precautions of Bearings

The SKF 21307 CC/C2 spherical roller bearing is a precision-engineered component tailored for applications requiring high load capacity and low vibration. This bearing is designed to handle substantial radial and axial loads in both directions while maintaining a close tolerance for enhanced performance. Here's a detailed overview of its technical specifications:

• Bore Diameter (d): 35 mm

• Outer Diameter (D): 80 mm

• Width (B): 21 mm

• Dynamic Load Rating (C): 79.2 kN

• Static Load Rating (C0): 72 kN

• Reference Speed: 7300 r/min

• Limiting Speed: 9500 r/min

• Mass: 0.54 kg

• Bore Type: Cylindrical bore

• Cage Material: Steel

• Radial Internal Clearance: C2 (Close)

• Tolerance Class: Normal

• Seal: Open (No Seal)

• Lubrication Enhancement: No lubrication groove or holes (W)

• Vibrating Screen Execution: Non-vibrating screen execution

The 21307 CC/C2's close tolerance (C2) and cylindrical bore provide a precise fit and operation, which is crucial for applications sensitive to noise and vibration. The steel cage ensures durability, while the lack of a lubrication groove or holes indicates a standard lubrication approach. This bearing is ideal for use in elevators, textile machines, food processing machines, cranes, and other heavy-duty machinery where high precision and reliability are paramount. The SKF 21307 CC/C2 is a testament to SKF's commitment to engineering excellence, offering a reliable solution for demanding industrial applications.
