2 row Tandem roller bearing T2AR1242 12x42x41.5mm in stock for extruder gearbox

الوصف

 Tandem bearings  T2AR***2 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  T2AR***2 with size *2x*2x*1.5mm, the inner diameter:12 mm, the outer diameter:*2mm, the total height:*1.5mm
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.
