Value Collection SRW155ZZS Miniature Ball Bearing

Product Description

The VALUE COLLECTION SRW155ZZS is a miniature radial ball bearing designed for compact rotating assemblies where space constraints and load requirements demand a precisely rated component. Referencing bearing number SRW155ZZ, this single-row bearing features a 0.1562-inch bore diameter, a 0.3125-inch outside diameter, and an overall width of 0.125 inches. It is rated for a static load capacity of 29 pounds and a dynamic load capacity of 81 pounds. The stainless steel housing and double-shield configuration make it suited for light-duty mechanical and electromechanical applications across HVAC, pump, motor, and instrumentation equipment serviced by qualified technicians and maintenance professionals.

This miniature ball bearing fits applications where standard full-size bearings cannot be used due to dimensional restrictions. Typical installations include small electric motors, fan assemblies, blower shafts, instrument mechanisms, and precision drive components found in residential and light commercial HVAC systems, pool equipment, and related rotating machinery. The ABEC-5 tolerance rating supports moderate-speed applications that require tighter dimensional accuracy than standard ABEC-1 or ABEC-3 bearings provide.

Key Features

• Miniature form factor: 0.1562-inch bore, 0.3125-inch OD, 0.125-inch width
• Double-shield design helps retain lubrication and resist contamination ingress
• Stainless steel housing material for corrosion resistance in demanding environments
• ABEC-5 tolerance rating for improved dimensional accuracy and reduced runout
• Single-row construction with round bore and no flange for straightforward installation
• Static load capacity of 29 pounds and dynamic load capacity of 81 pounds

Compatibility

Designed as a direct-replacement miniature ball bearing for rotating assemblies requiring a 0.1562-inch bore, 0.3125-inch outside diameter, and 0.125-inch width with a double-shield, no-flange configuration referencing bearing number SRW155ZZ.

Installation Notes

Installation is typically performed by mechanical or electromechanical technicians. Always de-energize and lock out the equipment before removing or installing any bearing. Use a proper bearing press or driver to seat the bearing evenly against the housing shoulder — never strike the bearing races directly with a hammer. Confirm shaft and housing tolerances are within specification before installation to avoid premature wear or race damage.
