Value Collection SFR155ZZS Miniature Flanged Ball Bearing

Product Description

The VALUE COLLECTION SFR155ZZS is a miniature flanged ball bearing designed for precision rotating applications requiring a compact, low-friction rolling element. With a bore diameter of 0.1562 inches and an outside diameter of 0.3125 inches, this single-row bearing fits tight-clearance housings in small motors, instruments, and light mechanical assemblies. The double-shield design protects internal components from contamination without requiring external seals. Rated ABEC-5 for dimensional accuracy and running precision, it is suitable for applications where standard ABEC-1 tolerances are insufficient. Installation is straightforward for maintenance technicians, equipment assemblers, and field service personnel working with small rotating machinery.

This bearing is suited for use in miniature electric motors, small fans, pumps, hand tools, and precision instruments where a flanged outer ring is needed to locate the bearing axially within a housing bore. The flange outside diameter of 0.3590 inches provides positive axial retention without additional hardware. The stainless steel construction makes it appropriate for environments with exposure to moisture or mild corrosives. It is sold individually and is compatible with shafts and housings machined to standard SFR155ZZ dimensional specifications.

Key Features

• ABEC-5 tolerance class for improved dimensional accuracy and reduced radial runout
• Double-shield design keeps lubrication in and contaminants out without contact friction of a seal
• Flanged outer ring with 0.3590-inch flange OD provides axial location in the housing
• Stainless steel housing material for corrosion resistance in wet or harsh environments
• Single-row, round bore configuration for radial load applications
• Static load capacity of 29 pounds and dynamic load capacity of 81 pounds

Compatibility

Designed as a direct-fit replacement for bearings carrying the SFR155ZZ dimensional standard, with a 0.1562-inch bore, 0.3125-inch OD, and 0.125-inch overall width. No snap ring is included or required.

Installation Notes

Installation should be performed by qualified maintenance or mechanical technicians. Always power down and lock out the equipment before removing or seating bearings. Press force should be applied only to the ring being interference-fitted — pressing on the wrong ring can damage the raceways. Consult equipment OEM documentation for housing and shaft fit tolerances before installation.
