Precision radial bearing for metric assemblies

The Tritan 61906 2RS PRX is a new 30 mm bore radial ball bearing built to metric dimensions for power-transmission and motion-control builds. Its 47 mm outside diameter and 9 mm outer-ring width match the 61906 and 6906 industry numbers, so it drops into standard housings without adapters.

Alloy-steel rings with contact seals

Both inner and outer rings are alloy steel, and the balls are AISI 52100 grade steel held in a steel cage. Double contact seals keep oil or grease inside while blocking contaminants, and the Polyrex EM lubricant is factory-filled for oily or greasy environments. A bore tolerance of +0/- 0.1 mm ensures a consistent press fit on the shaft.

ABEC 1 rating with 630 lbf dynamic capacity

Rated ABEC 1, the bearing delivers a dynamic radial load capacity of 630 lbf for steady rotation under moderate loads. The contact seals add slight drag but retain lubricant effectively, limiting noise and heat in continuous operation. No retaining ring is included, so axial location must be provided by the housing or shaft design.

Questions about this item

What does the ABEC 1 rating mean for the 61906 bearing's precision?

ABEC 1 is the standard tolerance grade; bore tolerance is +0/-0.1 mm and the bearing suits general-purpose radial loads.

What shaft and housing diameters fit the 30 mm bore and 47 mm OD?

The bearing mounts on a 30 mm shaft and seats in a 47 mm housing bore; both are metric dimensions.

Is the Polyrex EM grease already inside the double-sealed 61906-2RS?

Yes, the bearing ships pre-lubricated with Polyrex EM and the contact seals retain the grease.
