01. Maintenance-Free Sealing

Equipped with double contact rubber seals (2RS) made from NBR (Nitrile Butadiene Rubber), the bearing permanently retains factory-applied lithium-based grease. The light-contact lip seals provide effective protection against fine dust, moisture, and incidental splashing while maintaining low frictional torque .

02. Ultra-Thin Section Design

Manufactured from high-purity chrome steel (GCr15), this bearing features an extremely slim 6 mm width while maintaining a full 45 mm inner diameter. This thin-section configuration allows equipment designers to significantly reduce housing dimensions without sacrificing shaft rotational accuracy .

03. High-Speed Quiet Operation

The precision-ground raceways and carefully selected miniature balls are manufactured to strict vibration standards (Class V). This ensures exceptionally quiet running characteristics and minimal vibration, making the 6709-2RS ideal for noise-sensitive environments like medical laboratories and office equipment .

Design & Configuration

The 6709-2RS comes standard with double rubber seals, making it the preferred choice for "fit and forget" applications in relatively clean environments where maintenance access is difficult. The extra-thin section design (6 mm width) allows for compact equipment design without compromising on rotational stability.

For applications requiring higher operating temperatures or exposure to aggressive chemicals, full ceramic (Zirconia) versions of the 6709 are also available as a specialized alternative . For maximum speed requirements where contaminant exclusion is less critical, a metal-shielded version (6709-ZZ) can be considered.

"Where space is restricted and reliability is non-negotiable, the 6709-2RS delivers precision performance in an ultra-compact form factor, ideal for light industrial drives, automation, and precision instrumentation."
