A deep groove ball bearing is the workhorse of rotating equipment. It handles radial load plus a degree of axial load in either direction, tolerates high speed, and keeps a simple construction that makes it the least expensive option among ball bearings.

Reading the designation helps you order the right part. The first digits give the series, which sets width and load capacity. Next comes the coded bore diameter. Suffixes then tell you how the bearing is protected and what internal clearance it has. Two contact rubber seals appear as 2RS or 2RSH. Two non-contact metal shields appear as ZZ or 2Z. No suffix means an open bearing with no protection of its own. A C3 suffix, or another clearance number, signals internal clearance above normal, which suits a shaft that will run hot.

You will find these bearings in electric motors, pumps, fans, gearboxes and conveyor belts, and on practically any shaft turning at medium or high speed under moderate load. That range is why they cover most standard motors and gearboxes found on the market, and why they are the most common bearing held in an industrial warehouse.

Selection comes down to three things: shaft diameter, the load the bearing will carry, and the surrounding environment. A motor in a dusty or damp area calls for 2RS sealing. A high-speed shaft in a clean setting can use ZZ shielding, which produces less friction. Speed and operating temperature also determine the factory grease, and in a sealed bearing that grease cannot be replenished.

The design is among the most standardized in the industry. Inner diameter, outer diameter and width are made to matching numeric series by SKF, NSK, FAG, NTN, Timken and other manufacturers. If your equipment carries a different brand's designation, send that part number and there is usually a direct equivalent.

If you have the number stamped on the bearing or the shaft diameter, message us on WhatsApp with the part number. We will confirm the sealing options and the equivalent. We supply SKF deep groove ball bearings, from the smallest bores to the largest.
