When a bearing with a tapered bore has to sit on a plain cylindrical shaft, an NTN SK;H adapter sleeve does the job. The set combines a tapered sleeve with a lock nut and lock washer, so the bearing can be positioned and locked in place, then released again when service is due. This makes it a practical choice for transmissions, pumps, fans and similar machinery where the mounting has to stay firm yet remain adjustable.

Reading the code helps you match sleeve to bearing. In a reference such as 1204SK;H 204, the 1204 points to the bearing series, SK tells you the bore is tapered, and H 204 is the sleeve and nut designation. The same logic runs through 1304SK;H 304, 2204SK;H 304 and 2304SK;H2304. Use the bearing number to find the sleeve that fits it.

These sleeves appear throughout food processing, chemical, petrochemical and metallurgical plants. You will find them on power transmission equipment, centrifugal pumps, fans, mixers and conveyors. Because they let a bearing sit on a shaft that has no shoulder or step, machine design stays simpler and machining work is reduced. They also help when the axial position of the bearing has to be set, or when shaft tolerance is not tight.

Selection comes down to two things: the bearing series number and the shaft diameter. The sleeve has to match both the tapered bore of the bearing and the shaft it goes on. At mounting, keep the mating surfaces clean and free of burrs, and lock the nut with the washer so it cannot work loose. Lubricating the sleeve and bearing is part of correct operation and long service, and the tightening torque should follow the manufacturer's recommendation.

NTN adapter sleeves can be interchanged with sleeves from other makers that use the same designation system, including SKF, FAG and NSK. Dimensions and tolerances still need to be checked before you commit. If anything is unclear, send the original part number and the team will advise.
