Skf R3ZZST Deep Groove Ball Bearing 0.1875 in Bore

Product Description

The SKF R3ZZST is a deep groove ball bearing designed for applications requiring a compact, sealed radial bearing with reliable performance at high rotational speeds. Built with a stainless steel housing and a double-seal configuration, this bearing resists contamination and is suited for light-duty mechanical assemblies. The bore diameter measures 0.1875 inches, making it a miniature-class bearing. It carries a static load capacity of 110 pounds and is rated for speeds up to 40,000 RPM. ABEC-1 dimensional tolerances apply. Installation is straightforward for maintenance technicians and mechanical assemblers working in precision equipment, small motors, or instrumentation.

This bearing is used in residential and light commercial mechanical systems where a small-bore, high-speed radial bearing is required. Typical applications include small electric motors, pumps, fans, instrumentation, and precision mechanical assemblies. The double-seal design limits the need for field lubrication and helps keep contaminants out of the bearing raceway in environments where particulates or moisture may be present. The stainless steel construction adds corrosion resistance for damp or washdown-adjacent installations.

Key Features

• Deep groove ball bearing design handles radial and moderate axial loads
• 0.1875 inch bore diameter suits miniature-class shaft applications
• Double-seal configuration resists contamination and retains lubrication
• Stainless steel housing provides corrosion resistance
• Rated to 40,000 RPM for high-speed applications
• ABEC-1 tolerance class for standard dimensional accuracy

Compatibility

Designed as an OEM-style replacement for miniature deep groove ball bearings with a 0.1875 inch round bore and double-seal configuration in small motors, pumps, and precision mechanical assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with bearing press-fit procedures. Power down and de-energize all equipment before removing or installing bearings. Use proper bearing installation tools to apply force evenly to the bearing race - never strike the bearing directly with a hammer. Inspect the shaft and housing bore for wear or damage before seating the replacement bearing.
