12x21x5mm Compact Radial Bearing (6801-2RS)
Compact radial bearing with rubber shields. Ideal for smooth, space-efficient rotating lead screws, gearboxes, and other mechanical assemblies.
12x21x5mm Compact Radial Bearing (6801-2RS) is designed for smooth rotational motion in compact spaces, offering reliable performance where precision and environmental sealing are critical. This deep-groove ball bearing features a slim profile for space-constrained assemblies and includes dual rubber seals (2RS) to protect against dust and debris. Ideal for applications requiring low-friction rotation, compact size, and long-term durability.
Key Features
- Compact Design: Slim profile for tight-fit applications.
- Sealed Construction: Rubber seals on both sides protect against dust and debris for long-term reliability.
- Smooth Rotational Motion: Deep-groove ball design ensures efficient, low-friction operation.
- Reliable Performance: Ideal for space-constrained systems in motors, drives, and robotics.
Application
Radial bearings are commonly used in lead screws assemblies, gears, robotics, and other mechanical systems requiring compact, reliable rotation. The sealed design supports durability in environments where exposure to dust or moisture could otherwise compromise performance.
