S623 2rs Bearing Product Overview & Core Advantages
The S623 2RS is a sealed miniature deep groove ball bearing designed for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantage is the integration of NBR rubber seals (2RS) on both sides, effectively retaining lubrication and excluding contaminants, making it suitable for applications where maintenance-free operation is critical. This bearing is engineered to handle primarily radial loads and is optimized for smooth, quiet operation at high speeds.
S623 2rs Bearing Model Code Explained, Specifications & Naming Convention
- S623: Basic model number denoting a metric, single-row deep groove ball bearing with a 3mm bore, 10mm OD, and 4mm width.
- 2RS: Signifies that the bearing is equipped with two (2) contacting Nitrile Rubber (NBR) Seals (one on each side). This provides superior protection against dust and moisture compared to shielded or open bearings.
S623 2rs Bearing Structural Features & Performance Benefits
Full Stainless Steel Construction: The use of stainless steel for all critical components ensures high corrosion resistance, making it ideal for harsh environments or washdown applications.
Effective Sealing: The dual rubber seals (2RS) provide excellent defense against contamination, prolonging bearing life and maintaining performance by retaining the lubricant within the bearing cavity.
High-Speed Capability: With a limiting speed of 45,000 rpm, this bearing is designed for demanding high-speed applications such as small precision spindles and miniature motors.
Precision & Load Capacity: Manufactured to ABEC1 tolerance class, it ensures consistent and reliable operation. It offers a dynamic load rating of 108 lbf and a static load rating of 36 lbf, providing robust performance for its compact size.
