Tritan SS3843 ZZ FM222 Bearing

The Tritan SS3843 ZZ FM222 is a deep groove radial ball bearing identified by industry number 1621. It is designed for environments such as chemical, food and beverage, pharmaceutical, and poultry processing. The unit is supplied new and ready for installation in compatible machinery.

Stainless Steel Construction and Double Shielding

Both the rings and the balls are made from stainless steel, while the cage uses grade 304 stainless steel for corrosion resistance. A double shielded closure helps retain lubricant and exclude contaminants during operation. The bore diameter is 1/2 in with a tolerance of +0/-0.0003 in and an outer ring width of 0.438 in.

Replaces Worn 1621 Series Bearings

This bearing serves as a direct replacement for worn or failed units carrying the 1621 industry number. The upgrade is worth it when the existing bearing shows increased noise, vibration, or reduced dynamic radial load capacity rated at 175 lbf. It is not suited for applications requiring a flanged housing or a different bore size.

Questions about this item

How does the ABEC 1 rating affect the precision and speed limits of the 1621 bearing?

ABEC 1 sets looser tolerances than higher grades; the bore tolerance is +0 / -0.0003 in, so the bearing suits moderate speeds and standard radial loads rather than high-precision applications.

What shaft and housing dimensions are required to mount the 1/2 in bore, 1 3/8 in OD bearing?

The bearing needs a 1/2 in shaft and a 1 3/8 in housing bore; the outer ring width is 0.438 in, so the housing depth must accommodate that width.

How do you install the double-shielded 1621 bearing without damaging the shields?

Press only the inner ring onto the shaft or the outer ring into the housing using a sleeve that contacts the ring being fitted; never hammer the shields or apply force through the balls.
