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.

Questions about this item

What does the 6011 industry number tell me about which bearing to choose?

The 6011 designation confirms a 55 mm bore, 90 mm outside diameter and 18 mm width, so you select this exact size for shafts and housings matching those dimensions.

How does the 6,350 lbf dynamic radial load capacity apply once the bearing is installed?

It represents the maximum steady radial load the alloy-steel bearing can carry at rated life under oily or greasy conditions, assuming proper alignment and lubrication.

What does the ABEC 1 rating and open closure mean for speed and contamination limits?

ABEC 1 sets standard running accuracy and speed capability, while the open design allows lubricant flow but requires external seals to keep contaminants out.
