Value Collection SRW144 Miniature Ball Bearing ABEC-5

Product Description

The VALUE COLLECTION SRW144 is a miniature open-style ball bearing designed for precision light-load applications requiring tight tolerances and corrosion resistance. It carries an ABEC-5 precision rating and is constructed with a stainless steel housing. The bore diameter is 0.125 inches, the outside diameter is 0.25 inches, and the overall width is 0.0937 inches. Dynamic load capacity is 64 pounds and static load capacity is 20 pounds. This single-row, unflanged bearing suits instrumentation, small motors, and mechanical assemblies where compact geometry and dimensional accuracy are critical. Installation is typically performed by mechanical technicians or precision equipment service professionals.

The SRW144 fits applications where space constraints demand a sub-quarter-inch bore bearing with reliable load performance. Its open configuration allows for minimal friction in clean, low-contamination environments. Typical use cases include small electric motors, encoders, medical devices, light-duty conveyor mechanisms, and precision instrument assemblies. The stainless steel construction provides resistance to moisture and mild corrosive environments, making it suitable for both general industrial and light washdown service conditions where a full stainless bearing is warranted.

Key Features

• ABEC-5 precision rating for tight dimensional tolerances and reduced runout
• Stainless steel housing provides corrosion resistance in moisture-present environments
• Open style design minimizes drag in clean operating environments
• Single-row construction with round bore and no flange for straightforward housing fits
• 64-pound dynamic load capacity and 20-pound static load capacity in a compact envelope
• No snap ring included; interference or slip fit installation into housing bore

Compatibility

Designed as an OEM-style replacement or direct-fit miniature ball bearing for applications requiring a 0.125-inch bore, 0.25-inch OD, and 0.0937-inch width. Cross-reference bearing number SFW144 when sourcing equivalent replacements.

Installation Notes

Installation of miniature bearings should be performed with appropriate bearing press tools or a properly sized installation sleeve to avoid applying force through the rolling elements. The equipment shaft or housing should be powered down and de-energized before bearing removal or replacement. Avoid hammering directly on the bearing race. Cleanliness during installation is critical for ABEC-5 rated bearings, as contamination can degrade precision performance.
