Tandem bearings consist of several axial cylindrical rollerbearings arranged in line,
A system of rings and washersmatched to each other ensures that all stages of the tandem bearing are subjected to uniform load at all times irrespective of the ratio C/F.
The rings and washers are made from hardenedsteel. Tandem bearings are predominantly fitted with standardaxial cylindrical roller and bearing assemblies.
Structure and power flow
Design of bearing arrangements
For the installation of tandem bearings, the adjacent construction must be designed as follows:
1. with preload of one percent of the basic dynamic load rating
2. with radial guidance, for example by means of needle rollerbearings, Figure: Twin screw e xtruder g earbox.
3. without tilting. The adjacent parts must be machined such that no tilting
is transmitted
4. taking account of the spring constants of the tandem bearing,especially when combined with axial bearings of a differentdesign
5. with a mounting fit of f6 for the shaft and F7 for the housing bore, in order to achieve correct functioning of the bearings.
Lubrication
Tandem bearings are always operated with recirculating oil lubrication, Figure Oil outlet, oil inlet, dimensions.
We calculate the oil quantity and oil viscosity in accordance with the data given in thequestionnaire MCT.
Ordering example:
1. Tandem bearing with 6 stages
2. Shaft diameter 4 mm
3. Outside diameter 24 mm
4. Bearing width 105 mm.
