6203 Ball Bearings Compact metric bearings commonly specified as 17 mm bore, 40 mm OD and 12 mm width.
Deep Groove Bearings Common bearing type used for smooth rotation and radial load support in machinery.
ZZ Shielded Bearings Metal-shielded options where added protection is needed with lower contact drag.
2RS Sealed Bearings Rubber-sealed options where dirt, dust or moisture exposure needs closer control.
C3 Clearance Bearings Selected where the application calls for greater internal clearance than normal.
Stainless Steel Bearings Useful where corrosion exposure or washdown-style conditions are part of the requirement.
Electric Motor Bearings Compare by noise, speed, lubrication, clearance and operating environment where relevant.
Replacement Bearings Match the old bearing code and suffix before ordering a replacement.

What to Compare Before You Buy

The correct 6203 ball bearing depends on the exact suffix, sealing requirement, 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, C3, NR or stainless steel where applicable.
  • Check the core 6203 dimensions: 17 mm bore, 40 mm outside diameter and 12 mm width.
  • Match open, shielded or sealed construction to the application environment and contamination exposure.
  • Review clearance, material, cage, lubrication and speed requirements where shown in the product listing.
  • Consider shaft fit, housing fit, operating temperature, load direction, moisture exposure and maintenance access.
  • Use the BMG listing to compare BTC, NSK, NTN, Rollway, SNR and Timken 6203 bearing options online.

Common Uses for 6203 Ball Bearings

6203 ball bearings are commonly used in compact rotating assemblies, small motors, pumps, fans, conveyors, gearboxes, pulleys, workshop repairs, equipment maintenance and general industrial machinery where the 17 mm x 40 mm x 12 mm bearing envelope is specified.

For replacement work, check the old bearing markings before ordering. A 6203 bearing may share the same base size while differing by seal type, clearance, material or snap-ring groove configuration, so the suffix is often critical.
