8.18340 Roller bars, Hydraulic (figure 1)
max. load 160 kN/m, max. operating pressure 400 bar
Roller bar with hydraulic lifting of the complete bar for heavy loads and linear movement of the dies.
On the underside of the roller bar, lifting pistons are provided. Pressure is applied to thesepistons using hydraulic pressure generators,
which lift then the complete roller bar. The die positioned on the roller bars is not in contact with the table top and can be easily moved linearly and positioned. Any length up to 2500 mm is possible using modular segments.
Fixing of the roller bar using fixing bolts.

8.18341 Ball bars, Hydraulic (figure 2)
max. load 70 kN/m, max. operating pressure 100 bar
Ball bar with hydraulic lifting of the individual balls for medium loads and flexible horizontal movement of the dies.
Oil pressure is applied to lift each ball insert individually. The die positioned on the ball bars is not in contact with the table top and can be easily moved and positioned.
Any variable length in a single piece design up to 2900 mm.
Fixing of the bar using a fixing bolt or a wedge lock.

8.18342 Roller bars, Hydraulic (figure 3)
max. load 126 kN/m, max. operating pressure 120 bar
R
oller bars with hydraulic lifting of the individual rollers for medium loads and linear movement of the dies.
Contrary to the roller bars as per data sheet WZ 8.18340, the lifting pistons are below each roller. Each roller is lifted individually. The base body remains in its position. The die positioned on the rollers is not in contact with the table top and can be easily moved linearly and positioned.
Roller spacing and orientation are flexible.
Any variable length in a single piece design up to 2900 mm.
Fixing of the roller bar using a fixing bolt or a wedge lock.

8.1834 Ball Bars, Mechanical (figure 4)
with spring pack, loads up to 27 kN/m
Ball bar with spring pack for light loads and flexible horizontal movement of the dies. When preloaded, the balls project over the bed level by up to 2 mm. When the die is clamped, the balls are pressed into the bar body against the spring force until they are flush with the bed Level.
Flexible spacing of the balls.
Any variable length in a single piece design up to 2900 mm.
Fixing of the bar using a screw or a wedge lock.

8.18344 Roller bars, Mechanical (figure 5)
with spring pack, loads up to 66 kN/m
Roller bar with spring pack for medium loads and flexible horizontal movement of the dies. When preloaded, the rollers project over the bed level by up to 2 mm. When the die is clamped, the rollers are pressed into the bar body against the spring force until they are flush with the bed Level.
Roller spacing and orientation are flexible.
Any variable length in a single piece design up to 2900 mm.
Fixing of the bar using a screw or a wedge lock.

8.18345 Roller and Ball inserts, Mechanical (figure 6)
with spring pack, max. load 2.4 kN
When preloaded, the rollers or balls project over the bed level by up to 3 mm. When the die is clamped, the balls are pressed into the bar body against the spring force until they are flush with the bed level.

8.18347 Roller Conveyors, Mechanical (figure 7)
without spring pack, without lifting of the rollers
max. load 156 kN/m
These universal roller conveyors have been developed for easy and safe conveying of heavy dies.
All roller conveyors are manufactured in segments of 250 mm to which further segments can be added until the desired length is obtained.
The base bodies of the roller conveyors are made of a high-strength and robust aluminium alloy. The roller bars are fixed through mounting holes provided in the segments.

Hydraulic clamping pumps, manually operated: (figure 1)
max. operating pressure 100, 200 and 500 bar

In conjunction with our roller conveyors, dies can be economically clamped with these clamping pumps.
In addition, these pumps can be used for lifting of loads, for adjusting and locking of tables as well as other operating processes.
