The R12 series inch deep groove ball bearings feature standard dimensions of 3/4"x1-5/8"x7/16" (19.05x41.275x11.11mm), offering robust load capacity in a compact radial design—ideal for medium-duty industrial applications such as electric motors, water/oil pumps, exhaust fans, power tools, agricultural equipment, and light machinery.

Available in multiple sealing configurations to match your operating environment:

R12: Open type – minimal friction, ideal for clean or oil-lubricated systems
R12Z / R12ZZ: Single or double metal shields – reduce dust ingress while retaining factory grease
R12RS / R12-2RS: Single or double rubber seals – provide excellent protection against moisture, dust, and fine contaminants

Manufactured from high-quality chrome steel (SAE 52100) with precision grinding for smooth, quiet rotation and extended service life. Stainless steel (440C) versions are available upon request for corrosive or washdown environments.

These bearings support both radial and moderate axial loads, making them suitable for medium to high-speed operations where durability and reliability are essential.
