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.

配有介质通道的版本

SRM 旋转单元也可选配介质通道，使得压缩空气、气体或真空等能够可靠连通。对于型号 10、12、14 和 16，介质通道可以选择穿过并覆盖中心孔。对于型号 SRM 20、25、32 和 40，即使选装了介质通道，大中心孔也保持不变。

配有电路旋转通道的版本

SRM 旋转单元可选配电路通道，进而确保电信号以可靠方式通过。电路旋转通道在两侧均配有标准化且带有颜色编码的 M8 或 M12 电缆塞。大大简化了对信号流的识别，也使得调试更为简单。

通过电磁开关监控

SRM 旋转单元的各侧面均有两个 C 型槽，可安装雄克的 MMS 电磁开关。这确保能够灵活地对端位置进行监控，无需考虑 SRM 的安装位置。

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.
