The FAG H series adapter sleeve is a mounting accessory that secures a bearing with a tapered bore onto a cylindrical shaft. It works together with a lock nut and a lock washer to provide a precise, removable connection. In power transmission systems, this sleeve keeps the bearing correctly positioned and makes maintenance easier. MR Industrial Accessories LLC supplies this line as part of its range of mounting components.

The H series code starts with the letter H followed by a number that corresponds to the shaft diameter. For instance, H203 fits a 14 mm shaft and a bearing with a 17 mm bore; H204 fits a 17 mm shaft and a 20 mm bearing; H205 fits a 20 mm shaft and a 25 mm bearing, and so on. Suffixes that may appear after the number indicate length or thread variations, but the full part number always identifies the exact component. To choose the right sleeve, begin with the shaft diameter and the bearing you plan to mount.

Adapter sleeves are found in many types of industrial equipment, from machine tools and conveyors to pumps, fans and gearboxes. They are common in food, textile and cement plants and in metalworking operations where tapered-bore bearings must be mounted quickly and safely. They also suit applications where the shaft has no shoulder or step to support the bearing, because the sleeve allows the bearing to be fastened by interference.

For proper installation, confirm that the shaft tolerance is correct and that the surface is clean and free of burrs. Insert the sleeve into the tapered bore of the bearing and tighten it with the matching lock nut, which compresses the sleeve against the shaft. Respect the recommended tightening torque and use the lock washer to keep the nut from loosening. Lubricate the sleeve and bearing according to the manufacturer's instructions to support long service life.

When replacing a sleeve, consider interchangeability between brands. Although each manufacturer uses its own designations, H series sleeves generally follow standardized dimensions, so equivalents from other brands can often be found. Always verify the exact measurements and mounting conditions before substituting a part. Our team can help you identify the correct reference for your equipment.
