Planox® PT loaded by cup springs

The Planox® PT is a torque-limiting friction clutch in which permanently pre-tensioned compression spring columns generate a defined transferable torque. When the set torque is exceeded during operation, the clutch slips to protect the drivetrain from overload. Wear is automatically compensated by the compression springs, with the possibility of further adjustment where required.

  • Cup-spring loaded
  • Precisely adjustable transferable torque
  • Defined torque limitation
  • Drivetrain protection during overload
Torque1,320 Nm to 990,000 Nm

Choosing The Right Clutch For The Job

There’s a lot to consider when choosing the right DESCH product for your specific application.

Conditions

From environmental exposure to system constraints, the right solution must align with how your equipment runs.

Key factors to assess include:

  • Continuous and peak torque
  • Starting and acceleration loads
  • Operating speed

Torque & Protection

The key is not where they’re used, but how they perform in your application.

When evaluating use cases, consider:

  • Required torque transmission and peak load handling
  • Need for overload protection vs. continuous operation

Actuation & Installation

DESCH clutches are available in multiple actuation types, each suited to different operational needs.

Our options include:

  • Hydraulic actuation
  • Pneumatic actuation
  • Mechanical actuation
  • Cup-spring loading

Maintain For Longevity

While DESCH products are engineered for long-term performance, appropriate maintenance helps protect reliability, extend service life, and prevent avoidable downtime.

  • Select the clutch according to the required torque, speed, duty cycle, and operating conditions.
  • Install and commission the clutch according to the applicable DESCH documentation.
  • Check torque settings and actuation systems regularly.
  • Monitor friction components and investigate changes in engagement, slipping, noise, or operating behaviour.
