MRC‚Â® brand ‚â€œR Series‚â€ small inch-size ball bearings can fit smaller shaft diameters in rotating machinery while providing the capability to carry significant radial loads and substantial thrust loads in either direction, even at very high speeds. Their availability in stainless steel versions broadens their suitability for applications subject to corrosive conditions.
Unique design features of these single-row deep-groove radial conrad-type bearings include uninterrupted raceway grooves and optimized conformity between balls and raceways to accommodate very high thrust loads.
Bore sizes range from 1/8 in. to 1 1/2 in. and open, shielded, and sealed bearing types can be supplied. Basic radial dynamic load ratings range from 70 lbf to 3780 lbf and basic radial static load ratings range from 27 lbf to 2650 lbf, depending on type.
The ball bearings are equipped with pressed steel cages as standard. Two-piece riveted machined phenolic or bronze cages can be specified to meet particular application requirements.
CAD drawings for standard products can be downloaded free from www.skfusa.com/mrc and custom solutions can be developed through the MRC Made-to-Order (MTO) warranted products program.
