Bearings
Engineered bearings for optimized functionality
Hentec specializes in engineered bearings. We represent the leading brands:
- thyssenkrupp rothe erde®: Slewing bearings
- Federal-Mogul Deva: Self lubricated sliding bearings
- Waukesha Bearings: Fluid film bearings
- Cerobear: Ceramic- and hybrid ball- and roller bearings.
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

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.
rothe erde® seamless rolled rings and gear rings
- most progressive ring rolling mills allow consistent high quality
- outer diameter range from 300 mm to 8.000 mm
- delivered as blank or pre-machined/machined according to your drawing
- specific material testing according to your specifications
- nearly all classifications available
