Value Collection SFR4 Miniature Ball Bearing Flanged ABEC-5

Product Description

The VALUE COLLECTION SFR4 is an open-style miniature ball bearing designed for applications requiring precise, low-friction rotational support in compact assemblies. Built with a stainless steel housing, this single-row bearing features a flanged design that simplifies axial positioning and retention within a housing bore. It carries an ABEC-5 precision rating, making it suitable for applications where dimensional accuracy and reduced radial runout are required. With a static load capacity of 128 pounds and a dynamic load capacity of 335 pounds, the SFR4 handles moderate loads in small-envelope machinery. Mechanical technicians, equipment builders, and maintenance professionals typically install this bearing in motors, instrumentation, and light industrial equipment.

The SFR4 fits into compact mechanical assemblies where a 0.25 inch bore and 0.625 inch outside diameter are specified. Its flanged configuration is commonly used in through-bore housings where the flange seats against a mounting face for positive axial location without a separate retaining ring. Typical applications include small electric motors, pumps, conveyor systems, and precision instruments operating in environments where corrosion resistance is beneficial. The stainless steel construction supports use in mildly corrosive or washdown-adjacent conditions.

Key Features

• Flanged design with a 0.69 inch flange outside diameter for positive axial retention in housing bores
• ABEC-5 precision rating for reduced radial runout and tighter dimensional tolerances
• Stainless steel housing for corrosion resistance in demanding environments
• Open style allows for external lubrication and suits clean, dry operating conditions
• Single-row construction provides efficient radial load handling in a minimal axial footprint
• Static load capacity of 128 pounds and dynamic load capacity of 335 pounds

Compatibility

Designed as a direct-fit replacement or upgrade for miniature ball bearing applications specifying bearing number SFR4 with a 0.25 inch bore, 0.625 inch outside diameter, and flanged housing configuration.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with bearing fit tolerances and press-fit procedures. Always use a proper bearing press or installation tool applying force only to the ring being pressed; never strike the bearing directly with a hammer. Clean and inspect the housing bore and shaft before installation to ensure proper fit and prevent premature wear. Remove all power and de-energize any associated rotating equipment before servicing.
