SKF Food Line ball bearing units: the new standard in hygienic design

The SKF Food Line ball bearing units: Blue Range are hygienically designed to minimise the risks of product contamination. Relubrication-free and high-performance, even in challenging food and beverage processing environments, they allow companies to minimise labour costs while reducing the frequency of bearing replacements.

Sealed SRB with seals

Small sealed SKF Explorer spherical roller bearings with improved performance

With a new design that results in up to 50% less seal friction and as much as 20% less total bearing friction, these bearings reduce operating temperature by as much as 20 °C. As a result of longer lubricant life, they can be considered relubrication-free, reducing maintenance costs. In addition, they have double the limiting speed rating of previous SKF bearings, making them ideal for a wider range of applications.

A true story about belts’ extreme durability:
cycling 17,700 kilometres on 1 Gates Carbon Drive

Today’s story is about a bicycle belt rather than an industrial belt. Yet both share the same advantage: they are much more durable than their traditional, greasy counterparts. Get inspired by an adventurer’s love for his Gates Carbon Drive belt.

An intrepid traveller and his loyal companion

In 2013, Reza Pakravan, a cyclist who ranks among the world’s most seasoned travellers, pedalled from Norway to South Africa accompanied by just one Gates belt. That’s  17,700 kilometres rife with challenges such as rough and bumpy roads, different climate zones and weather conditions and extreme humidity.

As if that were not enough, Reza also cycled the length of the Trans-Amazonian Highway, through the jungle and over the Andes, again relying on his faithful Gates belt. Reza’s enthusiasm about Gates Carbon Drive – no maintenance, cleaning or lubrication required! – infected his travel companion, journalist Philippa Stewart, who was delighted that she “did not have to touch her Gates belt once” on her cycle ride with Reza.


Belt or chain? That isn’t really a question!

While Gates Carbon Drive can obviously not be used to drive bucket elevators, vertical lift systems, shaker tables and other industrial applications, Gates Poly Chain® belts can, and both systems have the same advantages:

  • they are completely maintenance-free
  • they last longer than chains
  • they don’t need lubricating
  • they will never rust
  • they are extremely strong.

NTN-SNR unveils with the French vehicle manufacturer, LAZARETH, the world’s first flying electric motorcycle, the LMV 496

For the third time, an innovative project brings together the two companies from the Rhône-Alpes region. The challenge is to design and build a motorcycle that can fly. The wheels fold out and the turbines positioned at the centre of each wheel enable the motorcycle to take off. NTN-SNR took up the challenge posed by a wheel-mounting design that allows the suspension arm to rotate and four engines to be inserted into the centre of each wheel. This world exclusive was unveiled at the party organised to celebrate the 20th anniversary of LAZARETH, held on 31 January 2019 in Annecy-le-Vieux.

The LMV 496: an exceptional project and a technical challenge

On the occasion of its 20th anniversary, LAZARETH, the vehicle manufacturer, took on an unprecedented and extraordinary challenge. It decided to build the first flying electric motorcycle, the LMV 496. Ludovic Lazareth naturally turned to NTN-SNR for assistance during this highly technical project. In order to develop this innovation, the entire design of the wheels and the bearings had to be reconsidered and an integrated solution put forward. The project concerns a tilting electric motorcycle whose two front and two rear wheels are twinned. While the motorcycle is in motion, the wheels fold out thanks to very specific kinematics and the motorcycle takes off, powered by four turbines positioned in the centre of each wheel. This unique model was unveiled to the public at the company's anniversary celebrations held on 31 January 2019 at Espace Rencontre in Annecy-le-Vieux.

100% NTN-SNR design and production

NTN-SNR teams were very much involved in and made a huge contribution to this project. Over a period of three months, an application engineer and a designer worked on this subject. The execution phase then began. At the beginning of December 2018, all four bearings were delivered to LAZARETH.

The challenge faced by NTN-SNR and LAZARETH was to place the engine turbines at the centre of the wheel – a space initially meant for the bearings. Vincent Pourroy Solari, NTN-SNR Innovation Manager explains: “LAZARETH gave us the scale model and the 3D files for the flying motorcycle’s chassis. With these elements, we studied and designed the wheel hubs, the wheel bearings, the engine mounts, the wheel mounts, as well as the arm joints so that the wheels can fold out when the motorcycle takes off. The main challenge was to reduce the weight so that the thrust of the four turbines enables the motorcycle to take off, while leaving room for the turbine in the centre of the wheel.”

In addition, the study covered the dimensions of the wheel bearings and joint bearings. It was also necessary to calculate (using the finite element method (FEM)) the deformation and constraint forces of all of the parts to validate mechanical performance in light of external stress (overheating of the turbine, management of stress from the ground and in flight, etc.). Finally, keeping the solution as light as possible was key: it could not weigh more than 2.2 kg per wheel.

NTN-SNR: a turnkey solution, technology packed into 2.2 kg

Technical characteristics:

  • Bearing solution that enables the turbine to be integrated into the centre of the wheel.
  • Ball bearing with four points of contact and a 240-mm pitch diameter.
  • “Serrated” bearing housing to optimise the guidance of the rolling elements while in motion and to ensure optimal weight.
  • Weight of the solution: 2.2 kg per wheel (with the attachments and attachment points)
  • Bearing equipped with a deflector to protect against external pollution.
  • 3D printing used to manufacture the key parts of the integrated solution.

The LMV 496 – the first flying electric motorcycle

  • Tilting motorcycle: the two front and rear wheels are twinned Total weight of the vehicle: 150 kg
  • Wheel: each fitted with a 5-kg turbine that provides 55 kg of thrust/li>
  • Motorization: electric motor
  • Range: 100 km

NTN-SNR and LAZARETH, a long-standing partnership

“Cooperation between the two companies began in 2013 with a project regarding an urban vehicle fitted with 4-kW engines, the Too’in. Our two companies are just as keen to work on these innovative projects,” notes Ludovic Lazareth.

The partnership continued in 2015. LAZARETH decided to launch an electric version of its well-known sports tricycle, the WAZUMA. NTN-SNR supplied the project’s wheel-motor technology. The E-Wazuma is equipped with two 30-kW electric wheel motors located in the rear twin wheels. “Working with Ludovic Lazareth on his emblematic vehicles is always a formidable challenge. It is also another opportunity for NTN-SNR to think outside the box, and that is what innovation is all about.” concludes Vincent Pourroy-Solari.



SKF New chassis grease LGLS 2

LGLS 2, NLGI 2 grade chassis grease, can offer excellent water resistance and stickiness to surfaces as well as very good anti-wear properties to your customers. This makes it a good solution for applications such as construction equipment, heavy duty off-road applications (such as excavators or wheel loaders), forestry and agricultural equipment (such as forwarders and harvesters), collector trucks, joints and slow plain and rolling bearings. LGLS 2 is mainly suitable for use via lubrication systems and comes in 18 kg and 180 kg pack sizes.
