The SKF deep groove ball bearing in the K/Q series is built for machinery that sees both radial and axial loads. Its single-row design with deep raceways delivers dependable performance at high speeds with low upkeep. Common installations include electric motors, pumps, and fans. MR Industrial Accessories LLC supplies this bearing and helps you confirm the right configuration for your equipment.
These bearings use a designation with two numbers separated by a slash, plus the suffixes K and Q. For instance, 6379/K-6320/Q identifies a bearing with a bore of 6379 and an outer diameter of 6320 in the SKF system for large sizes. The K suffix points to a tapered bore, while Q signals a special execution—often related to the cage or heat treatment. Reading these codes tells you the mounting and dimensional details before you order.
You'll find this series in food processing, chemical plants, petrochemical facilities, and power generation. They are a fit for centrifugal pumps, compressors, conveyors, and other rotating equipment that runs continuously. The ability to handle combined loads at speed also suits machine tool spindles and speed reducers where alignment and service life matter.
When selecting a bearing, look at the load direction, speed, and operating environment. A tapered bore (K) makes mounting with an adapter sleeve easier and allows a tighter fit on the shaft. The Q suffix can indicate a brass cage or a high-temperature treatment. Lubrication choices—grease or oil—depend on the application, and proper alignment plus sealing will extend service life.
SKF deep groove ball bearings interchange with other brands that follow the same ISO dimensional standards. To find a replacement, compare bore, outer diameter, and width, along with tolerances. Suffixes may differ by manufacturer, but the base designation usually matches. Send us the original code and we'll help you verify an equivalent.

Frequently asked questions
- What does the K suffix mean in this bearing designation?
- The K suffix indicates a tapered bore, typically with a 1:12 taper. This allows mounting with an adapter sleeve for a more precise fit on the shaft.
- How do I check if this bearing will work in my equipment?
- Compare the main dimensions—bore, outer diameter, and width—and the load type your equipment handles. If you send the original part number, we can confirm compatibility.
- Which lubrication should I use for these bearings?
- Lubrication depends on speed and temperature. Oil is often used for high speeds, while grease works for general applications. Contact us with your operating conditions for a specific recommendation.
