Series HE and SO

JOST Slewing Rings

Description:

Ball bearing turntables.

Applications:

For speeds up to 105km/h (65m.p.h)

  • Drawbar Trailers
  • Special Trailers

Features:

  • Ball bearing turntables are supplied undrilled.
    *drilled and primed in black for corrosion protection.
  • The measurements are subject to our standard tolerances.
  • The above axial loads are applicable if the slewing ring is mounted to the front axle of the trailer with three/four axles at speeds of up to 105 km/h (65 mph).
  • They can be exceeded by 10% for full trailers with two axles.
  • In case of speeds below 30 km/h (18 mph) the axial loads can be exceeded by 20%.
  • If required axial loads exceed the data permitted for turntables of series HE/SO, please ask for slewing rings of series KDL 900, which allow axial loads up to 250 kN.
  • In case of use above the steered axle and above the fifth wheel on semi-trailers with rear axle steering please enquire as to the load data giving details of the vehicle.
  • The load limits are only valid for operation on paved roads and under conditions prevailing in Europe.

DK 90/14

Double row ballrace, ball bearing race

Description:

Double row ballrace.

Applications:

  • Dairy Tankers
  • Sludge Tankers
  • Tri axle Tipping
  • Trailers

Features:

  • BPW turntables are equipped with supporting and retaining ball races between the upper and lower rings.
  • The axial forces on the turntables are accepted vertically via the large supporting ball bearings.
  • The horizontal tensile and compressive forces incurred are accepted by the smaller retaining ball bearings.
  • The moment forces resulting from braking and centrifugal forces, are mutually accepted by the supporting and retaining ball bearings.
  • The retaining ball bearings connect the upper and lower turntable rings.
  • The design principle ensures maximum reliability because the active axial and radial forces are distributed between the two ball races of BPW turntables.
  • The ball races are permanently protected against dirt and dust by a multi-lip seal.
