What to Compare Before You Buy

The correct 6312 ball bearing depends on the full suffix, sealing requirement, shield type, clearance, material, lubrication, speed, load and installation environment. Start with the bearing already fitted to the machine, then match the full product code as closely as possible.

  • Confirm the full bearing code, including suffixes such as ZZ, 2RS, CN, C3 or other configuration details.
  • Check the core 6312 dimensions: 60 mm bore, 130 mm outside diameter and 31 mm width.
  • Match open, shielded or sealed construction to the application environment and contamination exposure.
  • Review clearance, cage, lubrication, speed and noise requirements where shown in the product listing.
  • Consider shaft fit, housing fit, operating temperature, load, moisture exposure and maintenance access.
  • Use the BMG listing to compare BTC, NSK, NTN and Timken 6312 bearing options online.

Common Uses for 6312 Ball Bearings

6312 ball bearings are commonly used in electric motors, pumps, fans, gearboxes, conveyors, shafts, pulleys, plant equipment, workshop repairs and general industrial machinery where the 60 mm x 130 mm x 31 mm bearing envelope is specified.

For replacement work, check the old bearing markings before ordering. A 6312 bearing may share the same base size while differing by seal type, shield type, clearance, cage or lubrication configuration, so the suffix is often critical.

6312 Ball Bearing FAQs
