Purpose and Suitability

The TRITAN 61804 2RS PRX is a metric radial ball bearing designed for power-transmission equipment operating in oily or greasy environments. Its ABEC 1 rating and contact seals suit general industrial machinery where standard precision and contamination protection are required.

Build Quality and Daily Implications

The bearing uses alloy-steel rings and AISI 52100 grade balls held in a steel cage, lubricated with Polyrex EM grease. Double contact seals retain lubricant and exclude debris, while the 7 mm outer-ring width and 32 mm outside diameter determine the housing and shaft fit for routine maintenance planning.

Compatibility Checklist

Verify that your shaft provides a 20 mm bore with a tolerance of +0/-0.1 mm and that the housing accepts a 32 mm outside diameter. Confirm the application does not exceed the 900 lbf dynamic radial load capacity and that the metric ABEC 1 precision class meets the equipment specification before ordering.

Questions about this item

What bore diameter does the 61804 bearing use, and what shaft tolerance does it allow?

The bearing has a 20 mm bore with a tolerance of +0/-0.1 mm, so it fits shafts ground to that range.

What are the outer diameter and width that determine whether this bearing fits the housing?

The outside diameter is 32 mm and the outer ring width is 7 mm, giving the exact envelope needed for the housing bore and shoulder.

How is the double-contact seal installed, and what mistake damages the seal lips?

Press the bearing onto the shaft using a sleeve that contacts only the inner ring; pressing on the outer ring or seal flanges bends the contact lips and lets grease escape.
