Value Collection SFRW1-4 Miniature Ball Bearing Flanged

Product Description

The Value Collection SFRW1-4 is a miniature flanged ball bearing designed for precision motion applications requiring a compact, low-profile rolling element. Built with a stainless steel housing, this open-style bearing features a single row of balls and an ABEC-5 tolerance rating, making it suitable for applications that demand tighter dimensional accuracy than standard-grade bearings. With a bore diameter of 0.0781 inches and an outside diameter of 0.25 inches, it fits into tight assemblies where space is at a premium. The integral flange aids in axial location during installation. Maintenance technicians, equipment builders, and precision instrument technicians are the typical end users.

This bearing is used in small motors, precision instruments, medical devices, dental equipment, hobby robotics, and other miniature mechanical assemblies where a flanged design is needed to simplify axial positioning. The open construction allows for low starting torque and easy lubrication access, making it a practical choice for light-load, high-speed applications in both OEM manufacturing and field repair scenarios. The ABEC-5 rating supports moderate-speed applications with tighter runout tolerances than ABEC-1 or ABEC-3 bearings.

Key Features

• ABEC-5 tolerance rating for tighter dimensional accuracy and reduced runout
• Flanged outer ring simplifies axial location without additional retaining hardware
• Stainless steel housing resists corrosion in light-moisture or chemical environments
• Open-style design allows direct lubrication and reduces drag
• Single-row construction with round bore for straightforward shaft fitment
• Dynamic load capacity of 70 pounds and static load capacity of 23 pounds

Compatibility

Designed as an OEM-style replacement or direct-fit miniature flanged ball bearing for precision instruments, small motors, and compact mechanical assemblies requiring a 0.0781-inch bore and 0.25-inch outside diameter.

Installation Notes

Installation should be performed by a qualified mechanical technician or equipment assembler familiar with precision bearing practices. De-energize and lock out any equipment before replacing bearings. Press or seat the bearing using a proper bearing press or driver that contacts the outer ring only — never apply force through the rolling elements. Inspect the housing bore and shaft for damage or contamination before fitting the new bearing.
