Version with large end position adjustability

Large end position adjustability for variable adjustment of the swivel angle between 0° and 186°. Both end positions can each be limited by 90° (±3°).

Variant with pneumatic center position

The SRM swivel unit can optionally be ordered with pneumatic center position. This makes it possible, to control a third position in addition to the two end positions.

Bearing of the pinion

The pinion of the rotary module SRM is driven by two pistons, and is mounted at two points. The upper bearing is integrated in the pinion, whereby a minimum height of the entire unit is achieved. The lower bearing is pre-loaded free from play, whereby a very high accuracy and bearing stiffness is achieved. Both bearings are sealed to the outside with double-lip seals made of sturdy and durable FKM material.

Adjustment of end position and shock absorber stroke

The two end positions and the respective shock absorber stroke can be manually adjusted laterally on the unit. Due to the factory presetting of the shock absorber stroke, its adaptation is not necessary for many applications. The markings on the cover show the influence of the direction of rotation on the adjustment of the swivel angle

Version with external damping

In the basic variant of the SRM, the movement of the drive pistons is damped by the shock absorbers in the piston chamber. In the variant with external damping, the shock absorbers are mounted on the output side of the unit. Here, the movement is directly damped on the rotary table. As a result, higher moments of inertia and a higher repeat accuracy can be realized. In addition, full torque is available in all positions.

Variant with media feed-through

The SRM swivel unit can optionally be equipped with a media feed-through, which enables process-reliable feed-through of compressed air, gases, or vacuum. In case of sizes 10, 12, 14, and 16, the media feed-through can be optionally routed through the center bore, and in turn is covering it. In case of sizes SRM 20, 25, 32 and 40, the large center bore is completely intact, even if the option media feed-through is chosen.

Variant with electric rotary feed-through

The swivel unit SRM can optionally be equipped with an electrical rotary feed-through, thus ensuring operationally reliable feed-through of electrical signals. The electric rotary feed-through is equipped on both sides with standardized and color-coded M8 or M12 cable plugs. This makes it easy to identify the signal flow and simplify commissioning.

Monitoring via electronic magnetic switches

There are two C-slots on each side of the SRM swivel unit, into which the SCHUNK electronic magnetic switches MMS can be inserted. This ensures flexible monitoring of the end positions, regardless of the installation position of the SRM.

Monitoring via inductive proximity sensors and adjustable control cam

To monitor the end positions of the swivel unit with inductive sensors, an additional set-up is mounted onto the rotary table. For flexible monitoring of individual swivel angles, a version with adjustable control cam is available. This allows up to three positions to be inductively monitored.

Monitoring via inductive proximity sensors and fixed control cam

For simple commissioning and maintenance of inductive monitoring, a version with a fixed control cam is also available. This is not adjustable and therefore only available for swivel angles of 180° or 90°. As a result, monitoring of up to three positions is possible.
