SKF 6901 2RS 12x24x6 mm Deep Groove Ball Bearing

Technical Overview & Design Features

Compact Sealed Ball Bearing for Versatile Industrial Use

The SKF 6901 2RS is a deep groove ball bearing with dimensions 12 mm (inner diameter) x 24 mm (outer diameter) x 6 mm (width), equipped with dual rubber seals (2RS) to prevent dust, debris, and moisture ingress. Its compact and sealed design ensures reliable operation in environments where contamination control and compact dimensions are critical. This bearing is engineered to carry radial and moderate axial loads, making it suitable for a wide range of mechanical and industrial applications.

Key Advantages and Common Applications

Durable, Low-Maintenance, and Ready-to-Install

• Compact size for limited-space installations — The 12x24x6 mm dimensions make the bearing ideal for small motors, precision gearboxes, fans, electric tools, and other applications where space is at a premium.

• Sealed protection (2RS) for longevity and reliability — Dual rubber seals reduce lubricant loss and block contaminants, significantly extending service life and lowering maintenance needs.

• Balanced load capacity and smooth rotation — Deep groove geometry and hardened steel components provide stable performance under radial and axial loads, with low friction, consistent speed, and reduced vibration.

• Versatile industrial and commercial use — Suitable for electric motors, small gearboxes, household appliances, conveyors, pumps, and many other mechanical assemblies.

• Ready-to-install bearing unit — Standard measurements and sealed design allow easy integration into housings, shafts, or assemblies without further modifications, making it ideal for B2B supply and maintenance operations.

Detailed Product Description

The SKF 6901 2RS 12x24x6 mm deep groove ball bearing serves as a reliable and efficient solution for compact machinery, precise gear systems, and small-scale industrial applications. Its sealed design with rubber covers ensures that lubricant remains inside while keeping dust, moisture, and debris out — crucial for long service life and stable performance, especially in environments where contamination is a risk.

Due to its small overall dimensions, this bearing excels in compact assemblies such as small electric motors, handheld tools, fans, pumps, conveyors, and other equipment where space is limited. Despite its size, the bearing retains robust load capabilities — handling radial loads and moderate axial forces — while offering smooth rotation, low friction, and minimal vibration.

The deep groove construction and hardened steel races and balls guarantee consistent performance even under continuous operation. The sealed 2RS configuration means that maintenance requirements are minimal, which is a significant benefit in industrial or mass-production settings where downtime must be minimized.

Because SKF 6901 2RS matches standard dimension specifications and arrives ready for installation, it is particularly suitable for maintenance departments, OEM suppliers, and any business setting up or servicing machinery. The bearing seamlessly fits into standard housings or shafts and can be used to replace worn units without modifying existing assemblies — saving time and reducing the risk of incompatibility.

In summary, this compact ball bearing is an excellent choice for companies seeking a durable, sealed, and versatile bearing solution that combines performance, ease of installation, and low maintenance.
