01. Compact High-Performance Design

Belonging to the ISO 618 (Metric Thin Section) series, this bearing maximizes efficiency in tight footprints. Despite its small size, it boasts a dynamic load rating of 0.715 kN, offering a high power-to-weight ratio for modern mechatronics.

02. Ultra-Low Friction & Minimal Noise

Manufactured with P5/P6 precision grades as standard, the 685-2RS utilizes high-carbon chrome steel (GCr15) and super-finished raceways. This meticulous construction reduces torque and operational noise, making it ideal for noise-sensitive environments like offices and laboratories.

03. Superior 2RS Sealing Technology

The dual-lip nitrile rubber seals (NBR) provide a robust barrier against external debris. Unlike open bearings, the 685-2RS is designed to operate in harsher conditions where dust or light splashing may occur, ensuring the internal grease remains uncontaminated and effective for years.

Interchange Part Numbers

Common manufacturer equivalents for the 685-2RS:

• SKF: 618/5-2RS1
• NSK: 685DD / 685VV
• NTN: 685LLU
• KOYO: 685-2RS
• FAG: 61805-2RSR

Design & Configuration

The 685-2RS comes standard with dual-sided rubber contact seals for maximum protection. For high-speed applications where friction must be further minimized, we also offer the 685-ZZ (Metal Shields) or 685 Open variants. Customizations including stainless steel material (S685-2RS) for corrosion resistance or ceramic ball hybrid configurations for high-frequency environments are available upon request.
