ETP BUSH

Original hydraulic system connects with a single bolt

 

Our original hydraulic system connects with a single bolt. The shaft and hub are coupled by friction without use of keys, so the shortcomings and difficulties of key couplings are solved all at once. Its construction is simple, mounting and removal are easy, and it can accurately position and index. This greatly reduces work from the design stage to assembly, calibration, and maintenance. ,It can be mounted using a single bolt, and many models are available, including the ETP-T, which meets a concentricity of 0.006 mm.

ETP-E Plus Models

The axle and hub are connected by a single bolt, so installation can be done quickly and easily. Moreover, the concentricity is an excellent 0.02mm, so it is perfect for places where high precision is required and it will be frequently removed and installed. It is built to tighten radially, so it does not need a lot of space to operate.

Basic Specifications

  • Bore diameter : 15 mm to 60 mm
  • Max. rated torque : 3300 N-m
  • Concentricity : 0.02mm

ETP-T Models

The shaft and hub can be easily and quickly coupled using a single pressure screw.This facilitates assembly of equipment that requires positioning in the rotation and axial directions. It is also effective in locations requiring repeated mounting and removal. The concentricity of the shaft and hub is 0.006 mm, so ultra-precise positioning is possible as well.

Basic Specifications

  • Bore diameter : 15 mm to 100 mm
  • Max. rated torque : 18000 N-m
  • Concentricity : 0.006mm

ETP-E Models

The shaft and hub can be easily and quickly coupled using a single pressure screw.This facilitates assembly of equipment that requires positioning in the rotation and axial directions. It is also effective in locations requiring repeated mounting and removal. The concentricity of the shaft and hub is 0.02 mm, so relatively precise positioning is possible as well.

Basic Specifications

  • Bore diameter : 15 mm to 100 mm
  • Max. rated torque : 17000 N-m
  • Concentricity : 0.02mm

ETP-A Models

Shaft and hub can be easily and quickly coupled by tightening a clamping bolt located on the flange surface.Fastening is accomplished using fewer bolts than with mechanical systems, and there is no slotting as with mechanical systems, so high-precision coupling with a concentricity of 0.05 mm is possible.

Basic Specifications

  • Bore diameter : 15 mm to 100 mm
  • Max. rated torque : 15500 N-m
  • Concentricity : 0.05mm

ETP-H Models

Shaft and hub are strongly coupled by pumping oil into the sleeve under pressure to move the wedge of the built-in taper piston.The oil used for coupling is only necessary for moving the piston, so after coupling is achieved, the pressure is released and the taper piston is held in place by the wedge effect.

Basic Specifications

  • Bore diameter : 50 mm to 220 mm
  • Max. rated torque : 273000 N-m
  • Concentricity : 0.02mm
