Tandem Bearings Type
1. Basic Type: The bearing adopts elastic spacer to connect the shaft washer,housing washer, roller and cage assembly. The components of this Thrust Bearings are demountable. The user should assemble or dismount the bearing meticulously according to our guide book.
2. Shaft Type: The bearing is made by penetrating an axis through the inner bore of basic type bearing and fastening the bearing to the axis by locking collar/snap ring. The components of this type bearing are inseparable. Shaft type tandem bearing is variational structure of basic type.
3. Multi-stage cylindrical roller thrust bearing (sleeve type) locking collar is made by covering a sleeve to the external of the basic type multi-stage cylindrical roller thrust bearing. It is also inseparable,and is assembled and disassembled as a whole.
Application of tandem bearings
When using tandem bearings, the following recommendations should be adhered to:
1. Preload: 1% of the dynamic basic load rating. The dynamic basic load rating of each tandem bearing . Figures not listed will be provided by out institute on request.
2. Radial guidance: full complement cylindrical roller bearings or needle roller bearings can be used.
3. Eliminate tilting: the supporting parts must be machined to eliminate any tilting.
4. Mounting tolerances: recommended the following mounting tolerances: shaft f6 and housing bore F7.
5. Lubrication: tandem bearings must always be lubricated by oil circulation.
