Air Bearings Market: Likely To Experience A Tremendous Growth In Near Future 2019 - 2027

 Air Bearings Market: Introduction

Transparency Market Research delivers key insights on the global air bearings market. In terms of revenue, the global air bearings market is estimated to expand at a CAGR of ~ 7% during the forecast period, owing to numerous factors, regarding which, TMR offers thorough insights and forecasts in the air bearings market report.

In air bearings, the balls are replaced by a cushion of air. The most common application of air bearings is the hovercraft. Large fans blow underneath the hovercraft and the air is trapped under a flexible rubber ‘skirt’. This cushion not only supports the craft’s weight but also acts as a soft spring, which allows it to smoothly float over water or land. A similar principle is used by air bearings, where high pressure air is fed into the gap between stationary bearings and a rotational shaft. The gap is very small – around 1/100 of a millimetre, allowing the air pressure to be maintained within the bearing.

In this global air bearings market report, TMR predicts that, the aerostatic segment is expected to have a prominent share of ~ 56% in the global air bearings market, which was valued at US$ 4.3 Bn in 2018, and is expected to expand at a CAGR of ~ 7% from 2019 to 2027. Aerostatic bearings are preferred over the aerodynamic type, owing to their features such as high speed and higher acceleration during its operation.

This bearing can also support its entire designed load at zero speed. Aerostatic bearings can be used with low heat with accurate rotation. Additionally, aerostatic bearings are less rigid and are easier to handle smaller load capacities. Aerostatic bearings are useful in multiple applications such as micro-positioning, machining, and grinding that require frictionless superior performance at zero speed.

Air bearings are commonly used to support linear variable differential transformer (LVDT) cores to improve reliability and reduce gauging forces. Aerostatic bearings do not suffer from friction-induced wear, and additionally, they have no starting and stopping friction. Aerostatic bearings are popularly used in grinding, machining, and micro positioning applications, where full performance at zero speed and the absence of friction is extremely vital.

Air Bearings Market: Prominent Regions

North America held the second-largest share in the air bearings market, accounting for 29.9% of the overall industry in 2018. Technological advancements and the flourishing automotive industry in this region are primarily driving the air bearings market. The industry competition for air bearings is high, and investment and technology thresholds in this industry are relatively high. The demand for air bearings for industrial machinery is also expected to be highly stimulated by rising global manufacturing activity, which helps increase associated fixed investment expenditures. The dominance of the automotive industry over the years in the U.S has resulted in a rise in the demand for air bearings. Moreover, investments in research and development have also led to the strong growth of the automotive and space aviation industry in the U.S.
