17 mm Radial Ball Bearing

The TRITAN 6203 is a new metric radial ball bearing with a 17 mm bore and 40 mm outside diameter. It uses alloy steel rings and balls with a steel cage. The bearing is double sealed with contact seals and lubricated with Polyrex EM grease.

ABEC 1 Precision Limits

Rated ABEC 1, this bearing meets standard tolerance grades rather than high-precision classes. The bore tolerance is +0/-0.008 mm, and the dynamic radial load capacity is 2,150 lbf. These figures define the practical limits for speed and load in general-purpose applications.

Upgrade From Unsealed Or Lower-Capacity Units

This model replaces open or single-shielded 6203 bearings where contamination protection and higher load capacity are needed. The jump is worth it when equipment runs in dusty or moist environments and the 2,150 lbf rating matches the design load.

Questions about this item

Should I choose the 17 mm bore or the 40 mm outside diameter version?

The 6203 bearing has a fixed 17 mm bore and 40 mm outside diameter; they are not separate options.

What does the 150 lbf dynamic radial load capacity mean once the bearing is installed?

It indicates the maximum steady radial load the bearing can carry while rotating at rated life.

What does the ABEC 1 rating cap in practice?

ABEC 1 sets the baseline tolerance grade for bore diameter and running accuracy.
