  • TypeBearings, V-belts & Power Transmission Equipment
  • ColorTransparent
  • Stainless steel construction resists corrosion in oily environments
  • Double-shielded closure keeps lubricant in and contaminants out
  • 12 mm bore fits standard 6001 metric housings
  • ABEC 1 rating delivers reliable precision for general use
  • AISI 52100 alloy balls provide durable rolling performance

Precision Component for Specialised Builds

The Tritan 6001 ZZ FM222 is a new radial ball bearing manufactured from stainless steel. It suits engineers and hobbyists who require a metric 12 mm bore component for custom machinery or restoration projects. The double-shielded closure helps retain lubrication in oily or greasy environments.

Sustained Load Behaviour

Rated at a dynamic radial load capacity of 1,080 lbf with an ABEC 1 classification, the bearing is designed for steady operation rather than high-speed precision bursts. Its 304-grade stainless cage and 52100 alloy balls resist corrosion during continuous duty. The 8 mm outer ring width and 28 mm outside diameter maintain structural integrity under prolonged radial force.

Upgrade Path and Fitment

This unit replaces worn 6001-series bearings where a 12 mm shaft and 28 mm housing seat are specified. The bore tolerance of +0/-0.008 mm ensures a consistent press fit on standard metric shafts. It is not for applications demanding higher ABEC ratings, larger bore diameters, or flanged mounting surfaces.

Questions about this item

How much heat does the 6001 bearing generate under continuous 1,080 lbf dynamic load?

The ABEC 1 stainless-steel bearing runs on alloy-steel AISI 52100 balls with 304 stainless cage; friction stays low in oily environments, so temperature rise is minimal during all-day operation.

What shaft tolerance matches the 12 mm bore with +0/-0.008 mm fit?

The metric 12 mm bore accepts a standard h6 or g6 shaft; the negative tolerance ensures a secure press or slip fit without additional machining.

Will the double-shielded 28 mm OD bearing interchange with older chrome-steel 6001 units on the same housing?

Yes — identical 6001 envelope, 12 mm bore and 8 mm width mean it drops into existing housings; the 304 stainless rings and shields simply add corrosion resistance.
