Overview
The RBI 1605RS bearing is a sealed, precision deep-groove radial ball bearing designed for industrial automation, motion control, and general mechanical power transmission applications. This lot includes 10 units in new, unboxed condition. The 1605RS features a rubber-sealed design that protects internal components from contamination while maintaining self-lubrication through pre-applied grease.
Key Features
- Deep-groove radial ball bearing with plastic seals (RS) with optimum sealing action
- Pre-lubricated with grease and ready for use upon delivery; manufactured from Chrome Steel
- Maximum speed rating of 22,000 rpm with grease lubrication
- Low-maintenance sealed design suitable for dust and moisture exposure
- Bulk pack of 10 units – cost-effective for equipment assembly or replacement stock
Technical Specifications
The bearing features a 5/16″ inner diameter, 29/32″ outer diameter, 5/16″ width, and is rated for static load of 326 lbf and dynamic load of 835 lbf. Material composition and performance characteristics:
- Chrome Steel SAE-52100 construction with Chevron SRI-2 grease lubrication
- Basic load rating (Cr): 2.547 kN; basic load rating (Cor): 1.342 kN
- Oil speed rating: 30,000 rpm
- Bearing weight: 0.14 kg per unit
- Operating temperature range: –20°C to +120°C with standard grease
- Grade: ABEC-1 (Electric Motor Quality)
Typical Applications
The 1605RS bearing is used in applications including clutches, automotive components, electric motors, compressors, pumps, conveyors, belt drives, automotive starters, and medium-duty industrial applications. The sealed design makes it particularly suitable for equipment exposed to dust, moisture, or contamination in manufacturing, automation, and equipment assembly environments.
