WHEELS - BRAKES - Landing Gear
High performance for Aircraft


The Company BERINGER AERO has been manufacturing wheels  and brakes in the same spirit of quality and performance for 30 years. 

BERINGER brakes for motorbikes and cars have been accepted by the well-known racing teams for their exceptional reliability, allowing BERINGER to be used by many teams in the World Endurance Championships with many World Champion titles.
This was all made possible by a team of exceptional mechanical engineers who have studied and developed new products whose performance/weight ratio is without precedent, for each specific use.

Since 2002, BERINGER AERO makes WHEELS and BRAKES for a wide range of Aircraft from the ultralight airplanes up to its now-standard STC for the Pilatus PC-6 and the Cirrus SR22 that include everything for a bolt-on conversion.

These innovative solutions are covered by 9 international patents and have allowed BERINGER brakes to take a decisive technological lead.

Of course BERINGER controls product quality to ensure a total reliability to the users of wheels and brakes. This is evidenced by the Alternative Procedures to design Organisation Agreement given by EASA in 2006 and by the Production Organisation Agreement given by DGAC in 2008.

BERINGER wheels and brakes are designed to provide the best stopping power and the reliability you are expecting from a safe braking system. We propose a large range of assemblies: wheel / brake caliper / brake pad / brake disc. We also design and manufacture the optimal upstream components: reservoirs, master cylinders, the ALIR antiskid system, and parking brake valves. All these are tied together with top-quality braided stainless steel Teflon lines and proper fittings.
 Components and complete systems are available.



  •  High strength aluminum alloy machined from solid on CNC, anodized for optimal corrosion resistance
  •  TUBELESS wheel with O-rings and rigid valve
  •  SEALED BALL BEARINGS for optimal durability: greased for life, no maintenance
  •  Very low rolling resistance

During the design of a wheel we focus on three criteria: strength, weight, and durability. First, we assess the overall design and apply our experience and some hand calculations. Then we build a 3D model on CAD software and run FEM (finite element analysis) in the optimizing process, where we remove material from one side to add it on another, etc... till the result is satisfying for us with an optimized strength/weight ratio.
Then we make prototypes and start the qualifying process on our own bench machines. When the wheel has passed all the tests then we install the wheel on an aircraft for ground and flight checks.


The brake calipers are covered by the AEROTEC patent.
  • 2 or 3 stainless steel polished pistons
  • Body made of aerospace alloy to withstand high temperatures (>200Mpa at 200°C)
  • available for DOT4 fluid OR for MINERAL (MIL FLUID)  (seals are different; specify and never mix)
  • 2 inputs, thread size M10x1
  • Full metallic brake pads (no rivets) for extended life


  • Stainless steel disc or high strength steel disc with coating
  • Brake discs are made of highest quality material for thermal 
  • stability and long life


Many a ccidents occurring on the ground are due to a bad  control of the brakes
Avoid all these risks with the BERINGER ALIR on your aircraft

The BERINGER ALIR system improves the control of the brakes and helps the pilot to control the brakes.
This Anti-skid in Line Regulator allows the control of the direction on the ground with differential braking. It avoids wheel locking and risk of nose over when applying full effort on the braking pedals. It reduces the stopping distance.

                                    without ALIR

 EMERGENCY BRAKING : comparison of:

 - blue curve : with ALIR: the pilot applies full braking without any control (similar to a car ABS)
 - red curve: without ALIR: no regulation, the pilot must control the braking
 (in both cases, conditions are the same: same plane, same brakes) Weight of the aircraft: 1200 kg, braking speed: 70 Kt

 Nota: BERINGER brake pads used in the ALIR system have a friction coefficient that increases with the temperature allowing an increase of the deceleration when the lift decreases on the wings.


The BERINGER R&D laboratory is dedicated to Research, Development and Certification tests. 
On the wheel itself we do 3 different tests :
Load test: we apply different loadings on the wheel and tire (radial and side load) to check the strength and load rating of the wheel. Ultimate load tests go up to 6 times the static load using our 40,000lb hydraulic press capacity. 

Pressure test: Mounted tire is inflated with water up to 3.5 times the maximum inflation pressure to check bolts’ strength and wheel stiffness.

Roll test : Wheel is pressed on a rotating drum for 1000 miles at maximum static load to detect eventual fatigue problem or bearing failure, etc... 
When the wheel has passed all the tests then we install the wheel on an aircraft for ground and flight checks.

Note: when the wheel’s design work for the Solar Impulse was occurring, BERINGER’s proprietary dynamometer was employed, because of the Beringer wheel’ strength and our dyno’s exceptional ability to load and measure the tire. On the aircraft, that tire and its Beringer wheel (5.00-5) were of course run tubeless, at a pressure of 10 bar (over 140psi) and a static load of 3,850lbs  (2.7 times more than rated load).

Many tests are done to certify brake calipers and discs. One of those tests is the dynamic torque test; for this test we use our dynamometer. The kinetic energy capacity is tested with this machine. The dyno allows us to push the brake system to its limits. Many sensors are installed to measure temperatures. All these tests are performed to ensure the total safety and reliability of the brake system. 
Kinetic energy values indicated in the next pages are not only calculated but measured and checked on real tests.

The endurance test is also a proof of quality and durability. 
The purpose of this test is to verify the life of the parts. The certification test requires 100,000 cycles at maximum operating pressure, but we test our parts to a minimum 200,000 cycles. This represents more cycles than the brake system will be subjected to in the aircraft life.


Innovative solutions developped by BERINGER for motorbike and automotive World are covered by patents. These patented innovative researches are used by BERINGER AERO and applied to the aeronautical World. 
AEROTEC : braking system presenting a specific organisation in the mounting and assembling of the parts resulting in a drastic reduction of the hysteresis  phenomena, due to friction between the parts in motion. 
Limiteur Détendeur : pressure limiter device for the hydraulic circuit of a vehicle. 
Antibasculement  : when mounted on a vehicle, this braking pressure regulating device avoids it to nose over.
Lightec: braking disc for a vehicle including a braking rotor attached to the hub fitted on the wheel, with a movement capacity. 
Autobrake :  security braking device mounted between a reservoir of hydraulic fluid and the parts operating on the braking system. 
Asservissement freinage : servo-mechanism device on a vehicle allowing a deceleration strictly proportional to the braking effort applied by the driver.
