Value Collection SFR166 Miniature Flanged Ball Bearing

Product Description

The VALUE COLLECTION SFR166 is a miniature flanged ball bearing designed for precision motion applications requiring compact, reliable radial load support. Built from stainless steel housing, this open-style, single-row bearing carries a dynamic load capacity of 160 pounds and a static load capacity of 56 pounds. With a bore diameter of 0.1875 inches, an outside diameter of 0.375 inches, and an overall width of 0.125 inches, it fits into tight assemblies where standard bearings cannot. The ABEC-5 tolerance rating ensures consistent dimensional accuracy and low runout. Mechanical technicians and equipment assemblers working on precision instruments, small motors, and light-duty rotating assemblies are the primary installers of this bearing.

The SFR166 is suited for residential and commercial equipment applications where miniature bearings are required in compact rotating assemblies. Its flanged design allows it to seat positively against a housing shoulder, preventing axial migration without additional retention hardware. The open construction makes it appropriate for clean, dry or lightly lubricated environments where periodic access for relubrication is possible. Typical install scenarios include small electric motors, precision actuators, dental or medical equipment, hobby-grade drives, and instrumentation assemblies where space and weight constraints are critical factors.

Key Features

• Flanged outer ring with a flange outside diameter of 0.422 inches for positive axial location in housings
• ABEC-5 tolerance class for reduced runout and tighter dimensional control
• Stainless steel housing material for corrosion resistance in demanding environments
• Single-row, open design accommodates both radial and light thrust loads
• 160-pound dynamic load capacity and 56-pound static load capacity in a compact 0.375-inch OD envelope
• Round bore type for straightforward shaft fitment without additional machining

Compatibility

Designed as an OEM-style replacement or direct-fit miniature ball bearing for equipment requiring a flanged, open, single-row bearing with bearing number SFR166 and ABEC-5 tolerances.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with precision bearing fitment procedures. Press or drive forces must be applied to the correct bearing ring — never press through the rolling elements. Thoroughly clean the housing bore and shaft journal before installation to prevent contamination of the open bearing. Ensure the assembly environment is free of abrasive particles that could compromise the unshielded bearing cavity.
