The Quick Details

R1212, R1212Z, R1212ZZ, R1212RS, R1212-2RS Inch Deep Groove Ball Bearings 1/2"x3/4"x5/32" (12.7x19.05x3.967mm) – Sealed Bearings for Electric Motors, Pumps, Agricultural Equipment & Industrial Machinery


The R1212 series inch deep groove ball bearings feature standard dimensions of 1/2"x3/4"x5/32" (12.7x19.05x3.967mm), designed to handle moderate radial and axial loads in a wide range of industrial applications including electric motors, water pumps, small gearboxes, farm machinery, and conveyor systems.
Available in multiple sealing options to suit diverse operating environments:
  • R1212: Open type – ideal for clean or oil-lubricated systems requiring minimal friction
  • R1212Z / R1212ZZ: Single or double metal shields – reduce dust ingress while retaining factory grease
  • R1212RS / R1212-2RS: Single or double rubber seals – provide superior protection against moisture, dirt, and fine contaminants
Manufactured from high-grade chrome steel (SAE 52100) with precision-ground raceways for smooth, quiet operation and extended service life. Stainless steel (440C) versions are available for corrosive or washdown environments.
These bearings support both radial and bidirectional axial loads, making them suitable for continuous-duty applications where reliability and low maintenance are essential.
