Third position ZWP

intermediate positions and swivel-units torques

Intermediate-positions - which torque of modules vs. corresponding swivel-units?

The get a "third" position, pneumatic swivel units can be added with our module intermediate-position.
It is mounted directly to the swivel unit and moves two piston-rods inside the working area of the gear racks - by external pressurized air.
By pneumatic force, the piston-gears of the swivel units are pushed to the intermediate position.

Interested in more technical background? Please see this link.

The mid-position is adjustable (90° +/- 20°, in case of ZWP-9-SES 90° +/- 10°).
Keep in mind: as pushed via the piston-gears, the repeat accurracy also directly depends on the gear (0,05°).

Mid-positions are available corresponding to some of our swivel units. Please also find a link to a short YouTube-Video (in German).

According product dimensions, there is a "given maximium" of piston-diameter in the intermediate-position-module.

Depending on their size (module / variant) it is partially possible to work vs. the pressurized swivel unit. Please see table below.

swivel unit	torque swivel unit	torque ZWP	torque ZWP
module/size	@6bar effevtive	against swivel unit @6bar effective	swivel unit not pressurized
SE-4	0,94 Nm	impossible	0,9 Nm
SES-4	1,6 Nm	1 Nm	3 Nm
SE-6	3,5 Nm	impossible	3,5 Nm
SES-6	6,5 Nm	1,9 Nm	10,1 Nm
SE-9	12 Nm	5 Nm	20,2 Nm
SES-9	24 Nm	8 Nm	40 Nm
