Timken 6203 Radial Ball Bearing

The Timken 203KDDG is a metric radial ball bearing built to industry number 6203 with a 17 mm bore and 40 mm outside diameter. It suits machinery that requires a standard 6203 envelope and alloy-steel construction.

Double Shielded Closure Limits

Double metal shields keep coarse debris out while allowing higher speeds than contact seals, but they do not block fine dust or moisture. The ABEC 1 rating and SRI 2 lubricant set the precision and operating envelope for general-purpose rotation.

10 600 N Dynamic Load Capacity

The bearing carries a dynamic radial load capacity of 10 600 N, which determines whether it can handle the forces in your application. Buyers who need a higher rated capacity must select a different bearing.

Questions about this item

Which bore diameter matches my 17 mm shaft requirement?

The bearing has a 17 mm bore diameter with a +0/-0.008 mm tolerance, so it fits a standard 17 mm shaft directly.

What does the 10 600 N dynamic radial load capacity mean for my application?

It indicates the bearing can sustain a continuous radial load of 10 600 newtons at rated speed and life under normal lubrication.

How does the ABEC 1 rating limit precision in practice?

ABEC 1 sets the loosest tolerance class for metric radial bearings, so run-out and dimensional variation are larger than higher grades.
