01. Ultra-Thin & Space-Saving Profile

With dimensions of 40×62×12mm, this extra-light series bearing features minimized ring cross-sections, making it ideal for applications with strict radial space limitations while maintaining reliable load support.

02. Smooth & Low-Vibration Operation

Precision-engineered chrome steel raceways and balls, combined with optimized internal clearance, ensure quiet running with minimal vibration across various operating speeds.

03. Effective Dual Rubber Sealing

Integrated rubber contact seals on both sides provide dependable protection against contaminants and moisture, significantly extending bearing life in challenging or dirty environments.

Interchange Part Numbers

Common manufacturer equivalents include:

• SKF: 61908-2RS 
• NSK: 6908DDU
• FAG: 6908-2RSR
• NTN: 6908LLU
• KOYO: 6908LLB
• Timken: 6908-2RS

Design & Configuration

The 6908-2RS features double rubber contact seals, making it well-suited for environments exposed to light contaminants and humidity. For applications requiring even higher speeds or different sealing options, the double shielded variant (6908-ZZ) or open version (6908) may be considered as alternatives.

"A preferred choice for compact motor designs, precision automation, and medical devices, the 6908-2RS delivers effective sealing and dependable performance where space constraints and protection requirements are equally demanding."
