Radial Ball Bearing 61806

The Tritan 61806 2RS PRX is a metric radial ball bearing built with alloy steel rings and AISI 52100 grade balls. It carries ABEC 1 precision and a contact double-seal design suited for oily or greasy environments. The bore measures 30 mm with a tolerance of +0/-0.1 mm and the outside diameter is 42 mm.

Maintenance teams and OEM assemblers

This bearing fits shafts requiring a 30 mm bore and 7 mm outer ring width where a sealed, metric series 61806 or 6806 part is specified. It is not suited for applications demanding a higher ABEC class, a larger bore, or a different seal configuration such as shields or single seals.

Sustained operation in lubricated settings

The Polyrex EM lubricant and contact seals are formulated for continuous running in oily or greasy conditions rather than brief high-speed bursts. Dynamic radial load capacity is rated at 1,060 lbf, and the steel cage maintains ball spacing under steady loads without a retaining ring.

Questions about this item

What shaft diameter does the 30 mm bore of this 61806-2RS bearing fit?

The bore is 30 mm with a tolerance of +0/-0.1 mm, so it fits a nominal 30 mm shaft.

Can this ABEC 1 bearing run in the same assembly as higher-precision bearings I already have?

ABEC 1 is the standard tolerance class; it will operate alongside other bearings but sets the overall precision limit of the stack.

How can I confirm the bearing is rotating freely after installation?

Spin the inner ring by hand — it should turn smoothly with no binding, indicating the double-contact seals and Polyrex EM grease are functioning.
