Tritan 6011/C3 collectible 55 mm bore 90 mm OD 18 mm width

Industrial radial ball bearing 6011

This TRITAN 6011/C3 bearing is a precision radial ball bearing built for metric shafting with a 55 mm bore and 90 mm outside diameter. The open closure suits oily or greasy environments where relubrication is routine. Alloy steel rings and AISI 52100 balls rated to ABEC 1 deliver baseline running accuracy for general machinery.

Open closure limits contamination protection

Without shields or seals the bearing relies on the surrounding lubrication system to exclude grit and moisture; it is not suited to dry, dusty or wash-down settings. The steel cage and ABEC 1 tolerance provide standard radial guidance but do not meet tighter run-out or noise requirements found in higher ABEC classes.

Replaces worn 6011 series bearings on metric shafts

The jump is worth it when the existing unit shows excess radial play, noise or heat and the application can supply continuous oil or grease. It will not fit shafts other than 55 mm, nor housings bored for a different outside diameter, and it does not upgrade to a higher precision grade or sealed variant.
