Inch deep groove ball bearings

These are single-row deep groove ball bearings sized in inches: bore, outside diameter and width follow inch dimensions, not metric ones. They handle moderate radial load plus axial load in either direction and run comfortably at high speed. You find them mostly in equipment built in North America, farm machinery, pumps, fans and transmissions, wherever the shaft and housing are inch-sized.

Inch designations vary more than metric ones, since each series has its own prefix. SKF lists inch sizes in series like EE and EEB, and miniature inch bearings under D/W. Take the examples on this page: EE 2 TN9 and EE 3 TN9 end in TN9, a polyamide cage; EEB 3-2Z and D/W R3-2Z/P6 carry 2Z, meaning two metal shields, and P6 is a tolerance class tighter than normal. Under the MRC prefix, MRC.R10FF and MRC.R10ZZ cover bearings with those same dimensions.

Selection starts with three measurements, shaft diameter, housing bore and width, followed by the closure: open, shielded or with contact seals. Contact seals keep out more dirt and moisture; shields add less friction at high speed. Internal clearance depends on the fit and the operating temperature, which is why you should carry over every suffix from the original part number.

We supply SKF inch deep groove ball bearings. Send us the full part number stamped on the bearing or listed in the equipment manual. Without it, give us bore, outside diameter and width, or a cross-reference from another brand, and we'll identify the right part number. Ask for a quote on WhatsApp or by email and we'll get back to you promptly.
