Value Collection SR155ZZ Miniature Ball Bearing ABEC-5

Product Description

The VALUE COLLECTION SR155ZZ is a miniature radial ball bearing designed for compact mechanical assemblies that require precise, low-friction rotation in a small envelope. It features a 0.1562-inch bore diameter, a 0.3125-inch outside diameter, and an overall width of 0.125 inches. The double-shield construction keeps grease in and contaminants out without the drag associated with contact seals. Built to ABEC-5 tolerances, it delivers tighter dimensional accuracy than standard ABEC-1 or ABEC-3 bearings, making it suitable for applications where runout and noise matter. The stainless steel housing resists corrosion in humid or washdown environments. Licensed HVAC technicians, equipment repair technicians, and precision-equipment service professionals are the typical installers.

This miniature bearing is used in small motors, instrumentation, medical devices, HVAC actuators, blower assemblies, pumps, and other compact rotating equipment where space constraints rule out standard-frame bearings. The ABEC-5 rating and double-shield design make it appropriate for moderate-speed, light-load applications where dimensional consistency is more critical than raw load capacity. It is sold individually, making it practical for single-unit service repairs.

Key Features

• Double-shield design retains lubrication and excludes contaminants without contact-seal drag
• ABEC-5 precision tolerance class for tighter runout and lower noise than standard bearings
• Stainless steel housing construction for corrosion resistance in humid or wet service environments
• 81 lb dynamic load capacity and 29 lb static load capacity for light-duty rotating applications
• Round bore, no flange, no snap ring — straightforward drop-in replacement geometry
• Single-row construction in a compact 0.3125-inch OD package

Compatibility

Designed as an OEM-style replacement miniature ball bearing for compact rotating assemblies requiring a 0.1562-inch bore, 0.3125-inch outside diameter, and 0.125-inch width with double-shield configuration.

Installation Notes

Installation should be performed by a qualified technician familiar with precision bearing service practices. Always de-energize and lock out the equipment before removing the old bearing. Press or drive force must be applied to the bearing ring that will be seated — never press through the balls or across the rolling elements, as this damages the raceways. Verify bore and housing fits against manufacturer tolerances before pressing to final position.
