Triple ring bearings

Triple ring bearings

Triple Ring Bearings are uniquely structured bearing for ease of use and no creep while offering high precision and long life.
Major applications: CC rolls, press rolls, breaker stack rolls for paper mill machines.
Size range: 140 - 420 mm (Bore dimension)
Delivery: 30 Days

Combination tapered roller bearings have typically been used for the outside of controlled crown rolls (CCR) and spherical roller bearings for the inside. Switching to high-precision, high load capacity triple ring bearings prevents creep, facilitates easier mounting, and extends operating life.

Triple ring bearings are used almost exclusively in papermaking machines for the support of variable crowned press rolls at the drive side. 

FV produces three different types (inner/outer bearing):

Triple ring bearings-spherical roller bearings
  • cylindrical / spherical;  Kusters design (1)

  • spherical / cylindrical;  Farrel design (2)

  • spherical / spherical;  Beloit design (3)


The middle bearing ring is attached to the drive shaft via the shell of the variable crowned roll and all three types have threaded holes in the faces of the middle ring. The inner and outer rings of these bearings do not rotate; they are therefore mounted with a loose fit on the shaft (f6) as well as in the housing (G7).

The tolerances for the bore and outside diameters correspond to the normal toler- ances specified by ISO 492; the running accuracy is generally better than normal. The bearing internal clearance corresponds to the Normal clearance for each bearing of the triple ring combination.
