Value Collection SR1 Miniature Ball Bearing ABEC-5

Product Description

The VALUE COLLECTION SR1 is an open-style miniature ball bearing designed for precision rotating applications where compact dimensions and reliable load handling are required. With a bore diameter of 0.055 inches, an outside diameter of 0.1875 inches, and an overall width of 0.0781 inches, this single-row bearing fits into tight spaces that standard bearings cannot. It carries a dynamic load capacity of 52 pounds and a static load capacity of 16 pounds. The stainless steel housing provides corrosion resistance suitable for demanding environments. Machinists, equipment technicians, and precision instrument repair professionals are the typical installers for this class of bearing.

This bearing is suited for use in miniature motors, precision instruments, small appliances, medical devices, hobby and RC equipment, and other applications where space constraints demand sub-quarter-inch outside diameters. The open design allows for external lubrication and is appropriate for clean, low-contamination environments. Its ABEC-5 tolerance rating makes it a fit for applications requiring tighter dimensional accuracy than standard ABEC-1 or ABEC-3 bearings provide.

Key Features

• Miniature open-style design with 0.1875 inch OD for space-constrained installations
• ABEC-5 tolerance rating for improved dimensional precision and reduced runout
• Stainless steel housing construction for corrosion resistance
• 52 pound dynamic load capacity and 16 pound static load capacity in a compact form factor
• Single-row, round bore, non-flanged configuration with no snap ring

Compatibility

Designed as an OEM-style replacement miniature ball bearing for applications requiring a 0.055 inch bore, 0.1875 inch outside diameter, and 0.0781 inch width with an ABEC-5 rating and open style, bearing number SR1.

Installation Notes

Installation should be performed by a qualified technician familiar with precision bearing handling procedures. Always press or seat the bearing using the correct bore or outer race surface to avoid damage to the rolling elements. Ensure the shaft and housing are clean and within specified tolerances before installation. Do not apply impact force directly to the bearing face.
