Tr= Transmittable torque when axial force is 0.} Fr=Transmittable axial force when torque is 0./						At the mounting pressure acc. to above.							Dimensions subject to alteration without notice.

TOLERANCES

(E=160 000 MPa). Friction Coefficient, 7, between solid shaft and hollow shaft of 0,15 (well cleaned surfaces).

BUILT-IN

The contact area L must be covered by both the hollow shaft and the solid shaft mounted in the hollow shaft, before pressurizing.

CONNECTIONS

Axial and radial pumping connections, G 1/8, 180° apart.

LOCKING SCREWS

The locking screws are tightened to approx. 5 Nm, before the pressure is released. All the screws should be tightened equally.

SUPPLIER OF HYDRAULIC PUMPS

See the accessories section. Max. oil volume acc. to above refers to max. stroke, AB.

LOADS

Torque and axial forces are calculated for a hollow shaft of nodular iron


da (mm)	Tolerances, da
da (mm)	Solid shaft	Hollow shaft inside (mm)
70- 80	h6	+0,004 till +0,034
85-120	h6	+0,004 till +0,039
125-160	h6	+0,004 till +0,044
170-210	g7	H8

Outer diameter hollow shaft, d = h8.

MOUNTING

Mounting pressure acc. to above. Same for dismantling. All types of hydraulic oil can be used. Clean the contact surfaces between hollow/solid shaft thoroughly.

MAX. STROKE, AB

AB can be reached by largest possible play within the prescribed tolerances.

(250 or 350 bar)

(200 or 280 bar)

If the hardness of the hollow shaft is < 250 HB, the surface might be damaged. This can be avoided by reducing the mounting pressure. The transmittable torque will then be proportionally reduced. For example a hardness of 150 HB, a reduction of the mounting pressure by 20% is recommended.
