01.  Reliable Sealing for Harsh Environments

Two integrated rubber contact seals (2RS) provide effective protection against dust, splash, and humidity, extending component life in demanding operating conditions.

02. Smooth & Quiet Operation

Manufactured from precision-ground chrome steel with optimized internal geometry, this bearing ensures low noise, minimal vibration, and consistent running accuracy.

03. Ultra-Thin, Space-Saving Construction

With a width of only 9 mm, the 6905-2RS allows for significant design compactness and weight reduction in applications where axial space is at a premium.

Interchange Part Numbers

Common manufacturer equivalents include:

• SKF: 6905-2RS
• NSK: 6905DDU
• FAG: 6905-2RSR
• NTN: 6905LLU
• KOYO: 6905LLB

Design & Configuration

The 6905-2RS is delivered with two rubber contact seals as standard, ensuring robust defense against light moisture, dust, and common industrial contaminants. This makes it a versatile choice for a wide range of mechanical applications. For scenarios demanding extremely high rotational speeds within clean, dry operating conditions, an alternative double metal-shielded version (6905-ZZ) can significantly reduce friction.

"A robust and dependable bearing choice for auxiliary automotive components, light industrial drives, and general machinery where space efficiency and long-term reliability against environmental factors are paramount."
