HE 23 (HE 2300) Series Bearing Adapter Sleeves

Bearing Adapter Sleeves are commonly used for locating bearings with a tapered bore onto a cylindrical seat as they can be used on plain or stepped shafts. They are easy to install and require no additional location on the shaft. When adapter sleeves are used on plain shafts, the bearing can be located at any position on the shaft. When used on stepped shafts together with an L-shaped spacer ring, bearings can be accurately positioned axially thereby facilitating bearing mounting and dismounting.

Adapter sleeves with hydraulic assistance (Hydraulic Adapter Sleeves) facilitates mounting of large bearings. Oil pumps are required to inject pressurized oil. They are provided with oil ducts on the thread side and groove on the outer surface for oil injection internal upon request, facilitating the mounting and mainly the dismounting of the assembly.

The hydraulic adapter sleeve has the characteristics of prolonging the life of the bearing and protecting the bearing. It can be used in steel construction, cement mining, textile industry etc.
