Product Identity

The Tritan 3874 2RS PRX is a new deep-groove radial ball bearing identified by industry number 1652. It suits maintenance teams and machinery owners who need a direct replacement component for inch-measurement equipment.

Compatibility Check

Verify that your application requires a bore diameter of 1 1/8 in and an outside diameter of 2 1/2 in with an outer ring width of .625 in. Confirm the system runs in oily or greasy environments and that an ABEC 1 tolerance with a bore tolerance of +0/- .0004 in matches the original specification.

Build & Daily Use

Rings and balls are made from alloy steel with the balls graded to AISI 52100 for consistent hardness. Double contact seals retain the Polyrex EM lubricant and exclude contaminants during continuous operation. The steel cage maintains ball spacing under a dynamic radial load capacity of 880 lbf. No retaining ring is included, so plan the mounting method accordingly.

Questions about this item

What comes in the box with the Tritan 3874 bearing and do I need to buy a retaining ring separately?

The bearing is supplied as a single unit without a retaining ring; the specifications confirm no retaining ring is included, so one must be sourced separately if the mounting arrangement requires it.

Which capacity or version of the Tritan 3874 should I choose for a 1 1/8 inch shaft?

This model is a single specification — bore 1 1/8 in, outside diameter 2 1/2 in, width .625 in, ABEC 1, double-contact seals — so there are no alternative capacities or versions to select from.

What does the 2,880 lbf dynamic radial load rating mean once the bearing is installed in a machine?

It indicates the maximum steady radial load the bearing can carry while rotating at its rated life; actual service life will depend on speed, lubrication with Polyrex EM grease, alignment and the alloy-steel raceway and AISI 52100 ball condition.
