Precision Bearing for Industrial Use

The Tritan 6203 ZZ/C3 PRX is a shielded radial ball bearing built to industry number 6203. It fits shafts with a 17 mm bore and seats in a 40 mm housing. Alloy steel rings and AISI 52100 grade balls suit maintenance teams and OEMs specifying metric-dimension replacements.

Sustained Load and Lubrication

Double metal shields keep the Polyrex EM grease inside while excluding contaminants common in oily or greasy environments. The ABEC 1 rating and steel cage deliver consistent rotation under a dynamic radial load capacity of 2,150 lbf. Bore tolerance of +0/-0.008 mm maintains fit during extended duty cycles.

Deciding Specification — 12 mm Outer Ring Width

The outer ring width of 12 mm determines whether this bearing seats correctly in the designated housing. Verify this dimension against your equipment drawings before ordering. Buyers who need a different width or a retaining ring groove must select an alternative part.

Questions about this item

How much heat does the 6203 bearing generate under continuous 150 lbf radial load?

The ABEC 1 alloy-steel bearing runs on Polyrex EM grease in oily environments; sustained 150 lbf load produces typical rolling-element heat but no specific temperature-rise figure is published.

What shaft and housing tolerances must I already have for the 17 mm bore and 40 mm OD?

The bore tolerance is +0/-0.008 mm; the shaft should be ground to h6 or tighter and the housing bored to H7 so the double-shielded bearing seats without binding.

Will the 12 mm wide 6203 fit alongside an older ABEC 1 bearing on the same shaft?

Yes — both use the same 6203 industry envelope (17 mm bore, 40 mm OD, 12 mm width), so the new shielded unit interchanges directly with the older one.
