Standard Slewing Bearings

Our experts are trained to support customers and designers in the selections of the best suitable slewing bearing.

Optimized Slewing Bearings

For large diameters and very demanding applications, more continuous needs as well as higher volumes, optimized slewing bearings are mostly the best choice.

Sliding Bearings

Our self-lubricating sliding bearings are meant for very different applications, environments and requirements.

Fluid Film Bearings

The load is supported by a thin layer of rapidly moving pressurized liquid or gas.

Ceramic Bearings

Ceramic- and hybrid ball- and roller bearings for extreme requirements.

Expanding Pivot Pins

Expanding pivot pins for easy installation and exchange of pin and pivot bearings.


Bolting

Engineered bearings for optimized functionality

ITH is the worldwide leading system supplier in bolting technology. We help you with optimization of bolt connections, selection of the correct bolting methods, fasteners and suitable tools. We mainly work with sizes ranging from M24 up to M320 or even bigger.

You can choose between following ITH tightening methods:

  • Hydraulic tensioning
  • Hydraulic torquing
  • Electric torquing
Bolt Tensioning Cylinders

Hydraulic nuts can be used as a substitute for conventional hexagon nuts or standard round nuts.

Expanding Pivot Pins

Easy installation and removal + the ability to adapt to holes that are far from perfect are two of the advantages of Bondura® Expanding Pins, making them preferred in many applications over a wide range of markets. Bondura® designs and manufactures patented expanding pins, from a wide range of materials to suit the various applications and environments.  The pins are available from Ø25 mm up to more than Ø500 mm, in multiple designs depending on accessibility and various other factors. Special tools to facilitate easy removal are also available, for purchase or hire. 

Bondura 6.6

Can be installed from both sides of a support

Bondura 6.1

Assembled from one side, and torqued from the same side

Bondura 6.2

Assembled from one side, torqued from both sides

Bondura 3.3

A more simple version of the bondura® 6.6 and can be used in the same type of connections.

Bondura Dual 36

For locking both the inner and the outer part. Assembled and torqued from both sides.

Bondura Dual 66

Used when it is necessary to lock the inner ring of a bearing, at the same time as the outer conical sleeves are locked to the support bore.


Castings and Forgings

Your objective partner for casted components

Typically we deliver an entity or subassembly consisting of one or more castings & forgings that are machined, coated, assembled and inspected to be directly used in customers own assembly line.

Prototypes, serial deliveries or less frequent spare parts might require separate supply chains. Hentec helps you in finding the best balance.

In addition, Hentec helps customers with quality assurance. We have a vast experience in final inspections and have invested into a cutting edge optical 3D -scanning device to bring dimensional inspection to a new level.


Rolled Rings

Seamless rolled rings – mass perfection

rothe erde® rings are important components in a greatly varying range of applications. They play a key role in slewing bearings, large gear units, large valves, production facilities, sprocket wheels, wind turbines, and pipeline construction and can be up to 8 meters in diameter, seamlessly rolled. A ring of this type can easily weigh as much as 30 tons.
