When GripLoc shall be used in cramped installation spaces
or just one connection is completed.

The SCHAAF GripLoc PG 37 consists of the following components on a standard basis:

• Inner and outer tapered sleeves of high tensile strength steel for maximum strength
  
• Solidly fixed Hydraulic Nut
  
• Solidly fixed SafeLoc element as nut with thread
  
  
  

The different GripLoc characteristics by SCHAAF can be combined among each other. So for example GripLoc can be built integrated together with the SafeLoc mechanism in a removable Hydraulic Nut. An optimal solution is therefore guaranteed for each application.

SCHAAF GripLoc couplings are the optimum solution wherever high torques (forces) must be transmitted and, at the same time, easy and quick assembly / removal must be ensured. Contact us for optimally dimensioning your shaft and axle connections.

By radial shrinking of a hydraulically pre-extended external body GripLoc generates a radial stress on the two shaft or axle stubs to be connected. GripLoc is to be clamped and released rapidly.

Shrinkage and expansion of the tapered sleeves
provide the following advantages:

• Patented GripLoc sliding-on procedures for
  destruction-free interference fit assembling
  
• GripLoc can be removed simply and quickly
  even after years of use – again and again wearless
  
• High torque transmission, completely free from backlash
  
• Torsionally and flexurally rigid connection even with
  sudden changes in the rotational speed,
  torque, or direction of rotation
  
• Maximum torque transfer even in minimum installation space
  thanks to SCHAAF friction increase
  
• Separate, removable Hydraulic Nut – only one for
  a number of couplings (GripLoc PG 35, PG 36)
  
• Removability is always ensured if replacement of
  defective Hydraulic Nut seal is ever required
  
• Time saving on assembly and disassembly
