Product Overview: The SC 20 Set Screw Shaft Collar
The SC 20 is a simple yet essential mechanical component designed to securely fasten onto a 20mm shaft. As a set screw type shaft collar, it is one of the most cost-effective and widely used methods for positioning components, acting as a mechanical stop, or spacing elements within an assembly. By tightening the included set screw, the collar clamps firmly onto the shaft, preventing axial movement of bearings, sprockets, pulleys, and other parts. Its straightforward design ensures easy installation, adjustment, and removal.
Manufactured from durable materials, the SC 20 provides reliable holding power for light to medium-duty applications. It is a fundamental part of our Bearing Accessories collection, frequently used alongside various bearing types like the UC 204 or 6204 to ensure they are correctly located on the shaft. This versatility makes it an indispensable part in countless industrial and mechanical systems.
Key Features of the SC 20 Shaft Collar
- Set Screw Locking: Features a hardened set screw for strong clamping force and secure positioning on the shaft.
- 20mm Bore Diameter: Precision-machined to fit standard 20mm shafts for optimal grip and stability.
- Cost-Effective Design: Provides a reliable and economical solution for component positioning and retention.
- Easy Installation & Adjustment: Can be quickly installed, repositioned, or removed with a standard hex key.
- Durable Construction: Made from high-quality steel for excellent strength, wear resistance, and long service life.
- Smooth Bore: The inner surface is finished to prevent marring or damage to the shaft during installation and use.
