Adapter sleeve is easy to install and does not require additional fixing on the shaft. When an adapter sleeve is used on the optical axis, the bearing can be positioned anywhere on the shaft. When used with a stepped ring on a stepped shaft, the bearing can be accurately positioned axially, which also facilitates the withdrawal of the bearing.

Adapter sleeves are used to fix conical bore self-aligning bearings (spherical ball bearings, spherical roller bearings) on shaftless shoulder shafts, with simple structure and reliable operation, easy bearing replacement, widely used in textile, light industry, papermaking, Metallurgy, belt transportation and transportation equipment industries.
