SRW1-4 Bearing Product Overview & Core Advantages
The SRW1-4 is a stainless steel miniature ball bearing designed for precision applications requiring high reliability in compact spaces. As a single row radial ball bearing with an extended inner ring, it offers excellent performance in handling radial loads while providing a secure mounting surface. Its all-stainless-steel construction, including balls and cage, ensures superior corrosion resistance and operational stability across a wide temperature range from -86 to 230 °F, making it ideal for demanding environments.

SRW1-4 Bearing Structural Features & Performance Benefits
Engineered for precision and durability, the SRW1-4 features a single row ball bearing construction with 7 precision stainless steel balls for smooth operation. The extended inner ring width (0.125") enhances stability and facilitates easier installation and axial positioning. With an ABEC1 tolerance class and MC3 radial internal clearance, this bearing delivers consistent performance and low running noise. The all-stainless-steel composition, including the cage, provides excellent corrosion resistance and dimensional stability. Its compact bearing size (0.07813" bore × 0.25" OD × 0.0937" width) makes it perfect for space-constrained applications while maintaining a radial dynamic load rating of 49 lbf and capability to operate at limiting speeds up to 60,300 rpm.
