The Role of Bearings in the Aviation Industry

 


Though small in size, bearings are the backbone of many industries that involve rotary machines and equipment. The aviation industry is no exception.

However, this industry demands bearings that can handle extreme heat and immense pressures. They should be able to operate efficiently in corrosive environments.

In this blog, we look at a few important applications of bearings in this aviation industry.

Key Applications of Bearings in Aviation

Bearings offer frictionless, smooth rotational, and linear motion between moving parts in the aviation sector. Commonly, in aircraft components, they are used in engines, flight control systems, and auxiliary power units.

Flight Control Bearings

Control bearings are specially designed to ensure smooth and responsive aircraft maneuvering. But how do these bearings help? Basically, they minimize friction and enable precise movement of control surfaces like ailerons, elevators, and rudders.

For example, flight control linkages rely on spherical and needle roller bearings. These bearings are capable enough to operate under varying loads and temperatures while ensuring optimal control response.

Landing Gear Bearings

Landing Gear bearings are used in the undercarriage of aircraft to support its weight, take off and landing, in addition to their obvious role - offering smooth wheel rotation. These bearings evenly distribute the weight of an aircraft and absorb shocks during ground operations.

For this application, since bearings must bear high impact forces, temperature variations, and face environmental contaminants, high-load and self-lubricating roller bearings with special coatings make an ideal choice. These bearings can offer longevity.

Jet Engine Bearings

Jet engine bearings have to operate under a minimum of 1000°C. Additionally, rotational speeds over 50,000 RPM are the norm. Naturally, normal bearings cannot withstand such high mechanical loads, thermal stress, and lubricant degradation.

Therefore, for jet engine applications, bearings such as hybrid ceramic and coated bearings are a suitable choice. These bearings, when used with advanced steel alloys, can provide high efficiency and impressive durability.

Schaeffler’s Arcanol: Elevating Bearing Performance with Advanced Lubrication

Image
  Choosing the correct lubricant is essential in ensuring that rolling bearings and linear units can achieve the desired performance and service life. Schaeffler's Arcanol lubricating greases undergo rigorous quality tests before supply. The quality of each batch is thoroughly tested and accounted for. In Schaeffler’s own analytical laboratory, the Arcanol lubricating greases are checked for their chemical and physical properties following strict guidelines to ensure high product quality. Lubricants Schaeffler’s lubricants offer significant benefits, enhancing the running behaviour of bearings and extending the life and operational reliability of the bearing arrangement. The lubricant range is graduated in such a way that it can be used in almost all areas of applications. This is evident as they can withstand various operating conditions and are suitable for all rolling bearings due to their completion of different testing procedures. In 2015, Schaeffler conducted over 50,000 hou...

Types of Main Bearings Used in Marine Industry

Image
  Lead Bronze, Bi-Metal, and Tri-Metal bearings: These three types of bearings play a huge role in the marine industry. They are utilised to support rotating shafts and reduce friction to ensure smooth rotations. These bearings come with distinct benefits such as high load-bearing capacity, wear and corrosion resistance. Let us explore what these three bearings are made of, how many layers they have, and what they are used for. Lead Bronze Bearing Flash layer: This topmost layer is composed of tin and lead. It is 0.035mm thick. This layer’s job is to protect the bearing from getting corroded and dust when not being used. It flashes off when a bearing is running. Nickle Barrier: This 0.02mm thick layer - made of nickel - helps prevent corrosion and avoid diffusion of tin into bearing metal. Lead Bronze: The third layer comes with an anti-seizing property. It is made of lead bronze. This layer is great at preventing parts from sticking together. In the setup, it is the main part th...
