Hardening increases the wear resistance and thus the service life of the raceways and gearing. Heavily strained surfaces are surfaced hardened by an induction hardening process. These surfaces include the raceways and the gear teeth, if required by the design.

The advantages of GEN.1: compact, better reliability and simpler mounting process. It is one of the most used wheel bearings.

Full-surface hardening without soft spot is a worldwide unique and patented hardening process developed by Rothe Erde. This process is used for high-speed bearings such as rotor bearings in wind turbines.

A slewing bearing, also known as a slewing ring, is a machine element that absorbs all axial and radial forces and the resulting tilting moments, in a single, self-retaining and ready-to-install bearing unit.

The first applications used single row bearings, mounted in pairs. Compared to this type of conventional bearing arrangement, NTN GEN 1 wheel bearings incorporates 2 rows of rolling elements which require no setting (no pre-loading or alignment).

To meet the need for greater simplicity and reduce weight, expected by manufacturers, NTN offers a range of bearings where the inner and outer rings incorporate additional mounting functions: clamps, flanges or mounting holes for easy mounting onto the chassis of the vehicle.

NTN products are critical to keep the world moving smoothly. Our bearings and related products are present in a wide variety of industries. Please see the industries below that have applications for this product category.

In this machining step, the program-controlled turning of the contours takes place. These include the surfaces, pilots, steps, seal grooves, chamfers and raceways for the rollers or balls of the bearing.

3rd generation bearings incorporate two mounting functions: attachment to the chassis and the fixing to the disc brake and the rim of the wheel by the flanges incorporated into the inner and outer rings.

The goal is to quickly and easily transfer the forces acting on the slewing bearing to the adjacent structural machine elements. The overall design of the product, including the inner and outer rings, the gear cutting, rolling elements and mounting holes, enables it to transmit the applied loads and allow smooth rotation at the same time while maintaining a compact footprint. Slewing bearings enable and facilitate the rotational motion of wind turbines, excavators, cranes and tunnel boring machines, just to name a few. The slewing bearing offers many advantages compared to other solutions, including taking up significantly less space, weighing less and being more cost-effective in most cases.

The final inspection of the finished product is carried out internally by the certified quality assurance department or together with the customer and/or a designated 3rd party. During this process, the functionality and geometry are checked in detail. The basis for the inspection is the specifications that were agreed to during the design development or those specified in the contract. The test results are recorded in a written test report and in the QA documentation. The scope of the documentation is defined together with the customer in advance.

The functional demands placed on this highly technical product in terms of size, rotational properties, load capacity and service life are constantly changing as a result of dynamic markets. Whether, for example, a tunnel boring machine has to bore ever larger tunnels or wind turbines are getting bigger and bigger - we always find a suitable bearing solution. In the research and development center, which covers an area of 10,700 m², future-oriented developments are tested and all key components and materials are tested to their limits on our 20 test rigs. This allows the use of the components to be simulated under realistic conditions, thus enabling the products to be optimized further and further. In addition, the portfolio is constantly being developed and improved through cooperations with our customers, universities and external research institutes.

As a renowned manufacturer of slewing bearings, it is our aim to manufacture products and create solutions that operate reliably over the long term even in extreme environments and have an above-average service life.

We support you long beyond the warranty period to ensure the slewing bearing reaches its full service life. We offer assistance during installation and commissioning, inspection and maintenance services while the bearing is installed.

Wheelhub assembly

Hub bearings support the weight of the vehicle and allow the tires to turn smoothly. They are extremely important as they have a major impact on safety, as well as ride comfort and fuel efficiency. As the world leader in OEM wheel hub assembly market share, NTN is dedicated to developing bearings in an aim to support the ever changing needs of the OEM’s.

Miscellaneous roller bearings are bearings in which rolling bodies between an inner and an outer ring reduce the frictional resistance.

For the assembly, the rings are positioned on a rotating table. The specified number of balls or rollers are installed into the raceway.

NTN has developed different types of bearings for car manufacturers, depending on the vehicle and the performance requirements. We speak about a generation of bearings, currently called “GEN”.

NTN satisfies more than 30% of the demand for North American OE vehicle production from NTN’s Elgin, Illinois plant. The Elgin plant is the largest manufacturer of hub assemblies in North America, providing more product to OEMs and the Aftermarket than any other single facility. This gives NTN the benefit in the Aftermarket of supplying highly-engineered replacement parts that meet or exceed OE engineering specifications.

As a global manufacturer of slewing bearings with production facilities in Asia, Europe and the Americas and with a global sales network, Rothe Erde is able to supply products worldwide.

Gears can be cut either on the outer or inner ring. The gears are cut in several passes by the designated tooling. Gear cutting can be completed using one of the following processes:

Thanks to our extensive experience in both slewing bearing design and production, Rothe Erde is the world market leader for large diameter bearings.

First, the drilling takes place. A chamfer is then created at the top and bottom of the entrance. If required, an additional thread can be cut into the bore.

Depending on the design and required tolerances, the finishing of the product is carried out either by hard turning or by grinding. A combination of the two processes is also possible.

Numerous bores are arranged in rows in the axial direction for mounting the bearing and the load support. Between them are threaded holes for the stop screws in order to lift the bearing by crane.

In addition, the integration of the bearing in the vehicle can also provide a transmission function in the case of a driven wheel (drive provided via the spline in the bore).
