Twin Screw Extruder Gearboxes T4AR3075YB 30x75x112mm tandem roller bearing

Twin Screw Extruder Gearboxes T4AR3075YB 30x75x112mm tandem roller bearing 

 Tandem bearings T4AR3075YB consist of several axial cylindrical roller bearings arranged in line,  A system of rings and washers matched 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 hardened steel. Tandem bearings are predominantly fitted with standard axial cylindrical roller and bearing assemblies. The thrust cylindrical roller bearing T4AR3075YB with size 30x75x112mm, the inner diameter:30mm, the outer diameter:75mm, the total height:112mm

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.
