Adapter sleeves from NTN let you mount tapered bore bearings on plain cylindrical shafts. The sleeve sits between shaft and bearing, and a lock nut or nut with lock washer pulls it tight to create a firm, concentric fit. This makes assembly and disassembly simpler and helps avoid damage to the bearing. MR Industrial Accessories LLC supplies these sleeves to industrial customers across the United States and Latin America.
Reading an NTN adapter sleeve part number starts with the letter H. The numbers that follow tell you the series and the shaft diameter. The H30 series fits tapered bore bearings and includes codes such as H3026, H3068, H3072, H3076 and H3080. For larger bearings, the H31 series is used, with examples like H31/500. The H23 series, such as H2326, covers adapter sleeves for tapered bore bearings with specific dimensions. Suffixes and final digits give the diameter and thread pitch.
These sleeves are common in metallurgy, cement, mining, food processing and petrochemical plants. You will find them on conveyor belts, mills, pumps, fans and gearboxes where bearings mount on cylindrical shafts. They let a tapered bore bearing fit a shaft that has no machined taper, which simplifies machine design and maintenance.
Selection depends on shaft diameter, bearing type and locking method. Confirm that the thread matches your lock nut or nut and lock washer. Before mounting, clean the surfaces and remove any burrs. Apply the recommended lubricant and tighten the nut with the correct tool, keeping the bearing internal clearance in mind. Proper alignment reduces stress and helps the assembly last.
Adapter sleeves follow international standards, so different manufacturers' parts can be interchanged when dimensions and thread match. Always compare the complete part number and the measurements. If you are unsure, send us the original part number or the shaft and bearing measurements and we will help.

Frequently asked questions
- How do I identify the correct adapter sleeve?
- You need the shaft diameter, bearing type and locking system. With those details we can provide the matching NTN part number. If you have the original part number, send it and we will quote that same sleeve.
- Can NTN adapter sleeves work with other brands?
- Yes, when dimensions, thread and design match. Adapter sleeves are standardized, but always verify the measurements. If you send another brand's part number, we will tell you the NTN equivalent.
- What should I watch for when mounting an adapter sleeve?
- Clean the shaft and bearing bore, lubricate the threads, and tighten the nut with the proper wrench. Respect the bearing internal clearance and check alignment to prevent premature failure.
