AH3024 Adapter Sleeve
Selection Guide
Adapter sleeves and withdrawal sleeves secure a tapered-bore bearing onto a plain cylindrical shaft, eliminating shaft shoulder machining and greatly simplifying mounting and dismounting. Adapter sleeves are driven in with a locknut and tab washer; withdrawal sleeves use a hydraulic nut and suit larger sizes. Always verify: taper (commonly 1:12 and 1:30), shaft diameter, the mating bearing model, and the locking parts (nut, washer, hydraulic coupling). Judge drive-up by the reduction in bearing radial clearance — never overtighten by feel alone.

Can you provide engineering drawings and material certificates for AH3024?
Yes—CAD/DXF/PDF high-precision drawings and 3.1 material certificates (GCr15 bearing steel) for AH3024 are available on request from RAYSDE.
AH3024 How do I choose between an adapter sleeve and a withdrawal sleeve?
An adapter sleeve (H series) is simple and low cost: it is driven into the bearing bore with a locknut and tab washer, and removed by releasing the nut and pulling with a puller or hydraulic method — suited to small and medium sizes and infrequent removal. A withdrawal sleeve (AH series) works with a hydraulic nut, making mounting and dismounting easier and positioning more accurate, suiting large bearings and equipment serviced frequently. Give us shaft diameter, bearing model and service frequency and we will advise.
AH3024 How much clearance reduction is correct when mounting with an adapter sleeve?
As the sleeve drives the bearing up the taper, the inner ring expands and radial clearance decreases. For a spherical roller bearing with normal clearance, the reduction is typically held between 0.03 and 0.08 mm, varying with bore and series — larger bores allow a greater reduction. The correct method is to measure clearance with a feeler gauge or dial indicator during drive-up and stop at the target value. Driving too far eliminates clearance or creates negative clearance, causing rapid heat build-up and early failure.
