Marine

Lutex® HK series

Hydraulically actuated and oil-cooled, they use durable steel and sinter-bronze friction pairings to provide virtually wear-free operation and dependable performance under demanding operating conditions.

  • Low mass moment of inertia
  • Oil-cooled friction discs
  • Backlash-free engagement
Torque8,000 Nm to 187,500 Nm
Lutex-HK-HKE

Lutex® HK-E series

The Lutex® HK-E series is a hydraulically actuated, wet-running multi-disc clutch developed for applications requiring high torque at increased operating speeds and with larger shaft diameters. It provides the same performance data as the standard HK series while allowing a smaller clutch size to be selected where the shaft bore would otherwise determine the required clutch size.

  • Designed for high torques at increased operating speeds
  • Suitable for large shaft diameters
  • High torque-to-mass ratio
Torque11,200 Nm to 187,000 Nm

Choosing The Right Clutch For The Job

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

Conditions

Understanding how the drive operates is essential.

Key factors to assess include:

  • Required dynamic and static torque
  • Operating speed
  • Shaft diameter and maximum bore

Use Case

Lutex® HK and HK-E clutches are designed primarily for demanding marine drive systems.

When evaluating use cases, consider:

  • Higher-speed drives
  • Drives requiring large shaft diameters
  • Continuous-duty operating conditions

Configuration

The Lutex® range provides two configurations.

Our options include:

  • Lutex® HK: high torque in compact installation spaces
  • Lutex® HK-E: increased speed and larger shaft diameters
  • Multiple clutch sizes across each series
  • Application-specific

Maintain For Longevity

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

  • Install and commission the clutch according to DESCH instructions
  • Maintain the correct hydraulic operating pressure and oil supply
  • Monitor clutch engagement, disengagement and operating behaviour
  • Check the hydraulic system and connections regularly
  • Inspect the clutch and surrounding drive system as part of scheduled maintenance
