The R1038 series inch deep groove ball bearings feature robust dimensions of 3/8"x5/8"x5/32" (9.525x15.875x3.968mm), designed for medium-to-heavy radial loads in industrial applications such as electric motors, water/oil pumps, gear reducers, agricultural equipment, and conveyor systems.
Available in multiple sealing configurations to match your operating environment:
-
R1038: Open type – minimal friction, ideal for clean or oil-lubricated systems
-
R1038Z / R1038ZZ: Single or double metal shields – reduce dust ingress while retaining factory grease
-
R1038RS / R1038-2RS: 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 operation and extended service life. Stainless steel (440C) versions are available upon request for corrosive environments.
These bearings support both radial and moderate axial loads, making them suitable for continuous-duty machinery where reliability is critical.
