Value Collection SRW156ZZS Miniature Ball Bearing ABEC-5

Product Description

The VALUE COLLECTION SRW156ZZS is a miniature single-row ball bearing designed for applications requiring precise, low-friction rotational support in a compact envelope. It features a 0.1875-inch bore diameter, a 0.3125-inch outside diameter, and an overall width of 0.125 inches. Rated ABEC-5 for dimensional accuracy, this bearing delivers a static load capacity of 29 pounds and a dynamic load capacity of 81 pounds. The double-shield construction protects internal raceways from contamination without contact drag. The stainless steel housing material supports use in corrosive or washdown environments. Licensed mechanical technicians and precision equipment builders typically specify and install this component.

This bearing is suited for small motors, instruments, medical devices, robotics, and other precision assemblies where a miniature footprint is required alongside reliable load capacity. Its round bore and non-flanged profile allow straightforward press-fit or slip-fit installation into standard round housings. The ABEC-5 tolerance class makes it appropriate for moderate-speed applications where runout control is a priority. No snap ring is included, and the bearing does not feature a flange, making it compatible with housings designed for plain cylindrical outer rings.

Key Features

• ABEC-5 tolerance rating for controlled dimensional accuracy and reduced runout
• Double-shield design protects raceways from dust and light contamination
• Stainless steel construction for corrosion resistance in wet or chemical-exposed environments
• 29-pound static load capacity and 81-pound dynamic load capacity in a miniature package
• Single-row, non-flanged, round-bore design for standard cylindrical housing installations
• No snap ring required — simplified installation and reduced component count

Compatibility

Designed as a direct OEM-style replacement for miniature ball bearing positions calling for bearing number SRW156ZZ in precision mechanical assemblies and light-duty rotating equipment.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with bearing press-fit tolerances and cleanliness requirements. Power down and de-energize all associated equipment before removing or seating the bearing. Use a proper bearing press or installation tool that applies force to the ring being pressed — never strike the bearing directly or apply force through the rolling elements. Inspect the housing bore and shaft for burrs or contamination before installation.
