Product Identity

The Tritan 3876 ZZ PRX is a new radial ball bearing identified by industry number 1654 and built from alloy steel rings and grade AISI 52100 balls. It suits maintenance engineers and hobbyists who need a direct replacement for inch-series equipment running in oily or greasy environments.

Compatibility Check

Verify that your shaft measures 1 1/4 in and the housing accepts a 2 1/2 in outside diameter with a 0.625 in outer ring width. Confirm the application tolerates an ABEC 1 rating and a bore tolerance of +0/-0.00045 in, and that Polyrex EM lubricant is acceptable for the operating temperature range.

Who This Suits

Buyers replacing a 1654 series bearing in inch-dimension machinery where double shields and a retaining ring are not required will find this a direct fit. It is not for buyers who need a higher precision class, a sealed closure, metric dimensions, or a bearing supplied with a retaining ring included.

Highlights

  • Precision fit from tight +0/-0.00045 in bore tolerance
  • Smooth operation via ABEC 1 rating and AISI 52100 balls

Questions about this item

Does the 3876 ZZ PRX arrive as a single bearing or as a kit with retaining rings?

The bearing is supplied alone; the specifications state that a retaining ring is not included.

How do I decide between the ABEC 1 rating and a higher grade for this 1654 industry number?

ABEC 1 is the rated precision for this bearing; choose a higher ABEC grade only if your application demands tighter run-out tolerances.

What does the 2,880 lbf dynamic radial load capacity mean once the bearing is installed?

It indicates the maximum steady radial load the bearing can carry at rated speed without exceeding its calculated fatigue life.
