PTE will feature a variety of new component technologies online for bearings, motors, couplings, brakes, gear drives, and motion control systems leading up to Hannover Messe 2023 in Germany. Here is a preview of some bearings suppliers to check out if you're planning on attending the event online or in-person in April.

NKE Austria (Hall 5, Stand B05)

NKE Austria GmbH will present bearings for wind turbine gearboxes and generators. The Austrian bearing manufacturer has more than 20 years of experience in the wind energy sector. NKE bearings have been installed in more than 4,000 wind turbines across Europe, the USA and China, equivalent to more than 10,000 MW of installed power. 

"NKE bearings are used in the most important wind turbine components, that is gearboxes and generators, or as main bearings. We have final product approvals with major wind turbine manufacturers and are in the final stages of the approval process with others,” says Matthias Ortner, managing director of NKE in Steyr. "The strategic focus on sustainable technologies such as wind power and rail vehicles that was introduced three years ago is now bearing fruit. NKE is gaining a reputation as an innovative supplier of bearings for wind power.”

For example, NKE bearings are present in all bearing applications of the Envision gearbox: from the carrier (rotor side, generator side) to the high-speed shaft, including the intermediate shaft and planetary gearbox shafts. “For high-speed shafts, NKE cooperates with the customer’s engineering team to design bearings with enhanced profile and contact pressure,” says Michael Rössl of NKE’s Application Engineering department. “Another example are our new bearings with Power-Density technology: they are only 20 percent larger than conventional bearings, but they generate twice as much energy to optimize the output of the wind turbines and extract as much energy as possible from the air stream.”

C&U Europe (Hall 5, Stand C18)

Angular contact ball bearings can take radial load and axial load simultaneously. Single row angular contact ball bearings can only take single direction axial load, so angular contact ball bearings are often used in pairs. The paired angular contact ball bearings with manufactured clearance are the most convenient. The contact angles between steel balls and the inner ring/outer ring fall into 15°, 25° and 40°. The larger the contact angle is, the higher axial load it can take. The smaller the contact angle is, the higher rotation speed. Generally, contact angle of 15° is applied to high precision and high-speed bearings.

Single row angular contact ball bearings are designed with a certain contact angle, so they are suited to take single direction axial load or combined load. Structurally, axial thrust load will be generated after taking radial load, so angular contact ball bearings are often used in pairs, or more than two sets matched. The rigidity of single row angular contact ball bearings can be improved through preloading. Therefore, they are applied to the spindles of machine tools with high rotating precision. The contact angles of standard products including 15°, 25°, 40°. The cages of bearings with 15° and 25° contact angles are often made of plastic. The materials of the cages of bearing with 40° contact angle are made of copper, nylon, steel sheet, etc.

Timken (Hall 6, Stand B39)

Timken’s comprehensive line of single-, double- and multi-row Timken cylindrical roller bearings help extend equipment life and lower maintenance costs.

Single-row EMA series cylindrical roller bearings incorporate a unique cage design, proprietary internal geometry and special surface textures, available in a wide variety of size ranges and configurations.

Two-row, or double-row, cylindrical bearings offer added radial capacity and are interchangeable. Dimensions and diameters under the rollers (NNU style) and over the rollers (NN style) meet ISO standards.

Four-row cylindrical roller bearings withstand the rigors of daily use in applications where moderate and high speeds, high radial loads, elevated temperatures, and extreme debris present constant challenges.

Full-complement (NCF) single-row Timken bearings include integral flanges on the inner and outer rings. These bearings also can manage axial loads in one direction and permit small axial displacements.

Igus (Hall 6, Stand E26)

Lowering costs and raising service life with no lubrication and a reduction in maintenance work, everything delivered immediately from stock - that is the core idea and the objective of all iglidur polymer plain bearings. The igus plain bearings range includes sleeve bearings, flange bearings, thrust washers, piston rings, clip-on plain bearings, and many other designs. These plain bearings always offer a solution – either from the catalogue range or as custom-made plain bearing special solution. The iglidur bearings are suitable for all moving applications – from automotive mass production and special mechanical engineering, from underwater applications to the food or tobacco industry, for resistance to extreme temperatures and chemicals and for simple sheet-metal bushings.

The igubal is a system of self-aligning bearing elements made entirely of plastic. With igubal, a complete system of self-aligning bearing elements is available to the developer: Rod ends, clevises, flange bearings, spherical bearings, and pillow block bearings. Self-aligning bearings are easy to mount, adapt to all angular deviations and have already replaced special housings in many cases. With igubal, the user takes advantage of all the benefits of the high-performance plastics used. Technically dry applicable, they have very good vibration reducing properties. They are insensitive to dirt, can run in liquids and even in chemicals, and are completely corrosion resistant.
