Product Overview & Key Advantages
The ER1634 2RS is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. Engineered to primarily handle radial loads, this inch-series bearing features a compact design with a 0.75" bore and 1" outside diameter, making it ideal for space-constrained assemblies. Its sealed construction provides built-in protection against contamination, while its ABEC-1 precision class ensures consistent operation. This bearing is a robust solution for applications requiring dependable performance and extended service life.
ER1634 2RS Bearing Model Code Explained, Specifications & Naming Convention
- ER1634: Basic bearing designation with inch dimensions (0.75" bore, 1" OD).
- 2RS: Indicates the bearing is equipped with two rubber contact seals (RS), one on each side. This provides superior protection against dust, moisture, and other contaminants, making the bearing suitable for harsh environments.
ER1634 2RS Bearing Structural Features & Performance Benefits
Robust Construction & High Load Capacity: Manufactured from chrome steel rings and balls with a stainless steel cage, the ER1634 2RS offers excellent durability. It is rated for a dynamic radial load of 227 lbf and a static radial load of 155 lbf, providing reliable support for various mechanical systems.
Effective Sealing & Simplified Maintenance: The dual rubber contact seals (2RS) effectively retain lubricant and exclude contaminants. This design contributes to a longer service life and reduces the need for frequent maintenance, ideal for applications where re-lubrication is difficult.
Precision & Speed Performance: Built to ABEC-1 tolerance standards with a C0 radial internal clearance (0.006mm to 0.020mm), this bearing ensures smooth and quiet operation. It is capable of operating at a limiting speed of 8,000 rpm, making it suitable for a wide range of industrial speeds.
