NMB 1 Row Deep Groove Ball Bearing Shielded Chromium Steel 12 mm ID 21 mm OD 5 mm L-2112KKRA1P25LY121

The NMB L-2112KKRA1P25LY121 Ball Bearing is engineered for applications requiring high precision and reliability. With a compact form factor, this shielded bearing features a single row deep groove design, an inside diameter of 12 mm, an outside diameter of 21 mm, and a race width of 5 mm. Its construction in chromium steel delivers exceptional resistance to corrosion and wear, making it ideal for demanding environments.

The bearing utilizes a steel cage and steel balls, offering robust support for both static and dynamic loads. The shielded ends are specifically designed to prevent the ingress of dust and contaminants, which helps extend operational lifespan and minimize maintenance needs. With an ABEC 5 precision standard, this product is well-suited for use in precision instruments, chart recorders, and industrial machinery where consistent performance is essential.

Its parallel bore facilitates straightforward installation and ensures compatibility across various shaft types. The CN internal clearance provides flexibility to accommodate thermal expansion and shaft misalignment. The deep groove configuration allows the bearing to handle radial and limited axial loads efficiently, ensuring smooth rotation and reliable service.

This ball bearing is typically employed in industrial automation, laboratory equipment, manufacturing lines, and mechanical assemblies. Other applications include water treatment facilities, HVAC systems, and commercial machinery requiring high rotational accuracy and long-term durability.

The product is delivered with shielded race ends in a double metallic protection configuration and is manufactured to maintain performance even in challenging industrial settings. Durable corrosion-resistant chromium steel body.
