Precision Deep-Groove Bearing

The Tritan 3843 2RS PRX is a radial ball bearing built to industry number 1621 for machinery that runs in oily or greasy environments. It suits maintenance engineers and hobbyists who need a replacement part with a 1/2 in bore and 1 3/8 in outside diameter. The alloy-steel rings and AISI 52100 balls deliver reliable rotation under radial load.

Load and Speed Envelope

ABEC 1 tolerance sets the practical limit for precision, giving a bore tolerance of +0/-0.0003 in and a dynamic radial load capacity of 525 lbf. The contact seals and Polyrex EM lubricant are chosen for contaminated, greasy surroundings rather than high-speed purity. Designs that exceed the rated load or demand a higher precision class will need a different bearing series.

Sealed Construction and Fit

Double contact seals keep lubricant in and debris out, while the steel cage holds the ball complement at the factory-set 0.438 in outer-ring width. No retaining ring is included, so axial location must be provided by the shaft shoulder or housing bore. The transparent colour lets a technician confirm seal condition at a glance during routine inspection.
