The following points must be observed when using tandem thrust bearings.
(1)Preload: 1% of rated dynamic load should be put on the bearings first.please refer to the following Fig1~3 for the rated dynamic load for each type.For those not listed in the figs, please contact technical service .
(2)Radial guidance:Full complement cylindrical roller bearings or needle roller bearings can be used.
(3)Slop avoiding:The supporting parts must be machined to avoid any slop.
(4)Mounting tolerance:For proper using of tandem thrust bearings,we recommend the following mounting tolerance:shaft f6 and bore F7.
(5)Lubricant:Tandem thrust bearings must be lubricated by rare oil regularly.
(6)Mounting:When mounting or dismantling the bearings, it is prohibited to use hammer or other heavy tools to knock on the bearing parts.
(7)Application examples:As the tandem thrust bearings have the characteristics of limiting radial cross section, excellent axial loading capacity, long working life and low friction loss, they have been successfully used in the reduction gearbox for the parallel twin screw extruder in the plastic and rubber industry. Tandem thrust bearings are highly recommended to be used in other machines and equipment.
Tandem bearing customization:
Depending on the screw center distance, spacing and load size of the sample center, series bearings include two, three, four, five, six, seven or eight columns. We also accept series bearings in sizes and structures other than samples. If you need non-standard size, our company can also support customization
