SF694 2rs Bearing Product Overview & Core Advantages
The SF694 2RS is a metric single row deep groove ball bearing designed for precision applications requiring reliable performance in compact spaces. This sealed bearing excels in handling radial loads and is constructed entirely from stainless steel for enhanced corrosion resistance. Its key advantages include a compact flanged design for secure mounting, a sealed construction for contamination protection, and compliance with ROHS and REACH standards, making it suitable for high-reliability and demanding environments.
SF694 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2RS | Bearing is fitted with two Nitrile Rubber (NBR) contact seals, one on each side. | Provides excellent protection against contaminants and retains lubricant effectively, enhancing bearing life. |
| Flanged Design | The outer ring features an integral flange. | Simplifies axial location and mounting, offering a secure fit in housings. |
SF694 2rs Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured with stainless steel rings, cage, and balls, this bearing offers superior corrosion resistance and durability, ideal for harsh or washdown environments.
High-Speed Capability: The single row deep groove geometry and optimized design contribute to a high limiting speed of 43,200 rpm, supporting demanding operational requirements.
Radial Load Capacity: Engineered to handle significant radial dynamic loads (165 lbf) and radial static loads (57 lbf) within its compact bearing dimensions (4mm bore, 11mm OD).
Precision & Stability: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring smooth and consistent operation.
Low Maintenance: The 2RS seals and pre-lubrication requirement provide long-term, maintenance-free service by protecting the internal components from contamination and preserving lubricant.
