Tenbusch Line-Up Assembly Tenbusch Line-Up Assembly Tenbusch Line-Up Assembly Tenbusch Line-Up Assembly

The Line-Up Bearing Assembly is a tool used in Guided Boring / Pilot Tube Micro Tunneling. It bolts onto a large diameter cutting head, allowing the head and larger casing to follow precisely the line and grade of the previous installed smaller casing.

By using a bearing, the front of the assembly stays stationary, as the large head rotates.

Aspects of the Tenbusch Line-Up Bearing Assembly:

  • Rotary Bearing – Makes it possible for part of the assembly to remain stationary and mated inside the smaller casing while the larger cutting head rotates. This ensures the larger bore follows the line and grade of the smaller casing.
  • Seal – keeps debris and abrasives out of the bearing ensures proper mating and function of the bearing, crucial to keeping the larger diameter head and casing on precise line and grade.
  • Bolt On Assembly – design allows for minimal alteration of the existing large cutting head. Head can be used for intended use and cutting with minimal alteration after job is complete.

Line-Up Bearing Assemblies are custom built to the specifications of your job and larger cutting head. Low lead times – our products are designed and manufactured in Lewisville, TX, USA.

Tenbusch Tunneling Muck Cart and Track Tenbusch Tunneling Spoil Bowl Tenbusch Tunneling Spoil Bowl Dump Tenbusch Tunneling Track Rack

Tenbusch Inc. designs and manufactures custom spoil removal equipment for conventional pipe-jacking and liner plate tunneling applications. Tenbusch track is designed with the following features:

  • Designed to be easily bolted together in the tunnel,
  • Customer specified track gauge and track lengths,
  • Sized for maximum strength and rigidity,
  • Kept as light as possible to make it easy for the workers to install.

The spoil bowl is separate from its cart so as to be easily removed and dumped. The bowl is designed to automatically dump when lifted by the appropriate lift point. Quality design, function, and manufacture.
