SFRW2-5zz Bearing Product Overview & Core Advantages
The SFRW2-5zz is a single row ball bearing designed for precision applications requiring reliable radial load capacity. Manufactured entirely from stainless steel with shielded construction, this bearing offers excellent corrosion resistance and contaminant protection. Its extended inner ring facilitates easier mounting and secure positioning. With an ABEC1 tolerance class, it provides dependable performance for a wide range of industrial and precision instruments.
SFRW2-5zz Bearing Model Code Explained, Specifications & Naming Convention
The model number SFRW2-5zz breaks down as follows:
- SFRW: Denotes the specific bearing series with an extended inner ring design.
- 2-5: Indicates the bore size code, corresponding to a 1/8" (0.125") bore diameter.
- zz: Signifies that the bearing is equipped with shields on both sides (non-contact). This provides protection against contamination while minimizing friction.
SFRW2-5zz Bearing Structural Features & Performance Benefits
- Robust Construction: Built entirely from stainless steel (rings, balls, cage), ensuring high corrosion resistance and durability in harsh environments.
- Effective Sealing: The double-sided shields (zz) protect the internal components from dust and debris, enhancing bearing life without significantly increasing friction.
- Precision Performance: The ABEC1 tolerance class guarantees consistent running accuracy, making it suitable for applications requiring smooth operation.
- Optimized Internal Geometry: Features 6 balls of 1/16" diameter, providing a balanced load distribution and contributing to the radial dynamic load rating of 96 lbf.
- Extended Inner Ring: The design allows for secure axial location and simplifies installation in assemblies.
SFRW2-5zz Bearing Typical Application Areas
This bearing is ideally suited for:
- Small precision motors and gearboxes
- Medical and dental handpieces
- Optical encoders and instrumentation
- Office automation equipment (printers, scanners)
- Radio control models and small robotic joints
- Low-torque, high-speed spindles (up to 99,000 rpm)
