Air Bearing Spindles Market: Global Share, Size, Growth, Trends & Outlook ( 2022 – 2032 )

Air bearing spindles are the motor-driven shafts that either transmits power to a cutting tool or holds a workpiece. Air bearing spindles are being designed and manufactured for several advanced industries such as printed circuit board (PCB), high volume automotive/industrial coating, semiconductor manufacturing, and precision machining. It offers an advantage of very low error motions owing to the fluid-film-averaging effect, cleanliness, high-performance & frictionless positioning, and less maintenance. This is one of the main drivers of air bearing spindle demand.

For industries, such as semiconductor processing, air bearing spindles are being used to provide a smooth, repeatable, and accurate motion resulting in superior surface texture. Contrasting to the ball bearing spindles, air bearings ensure least subsurface fracture in machining of hard materials by delivering a constant bearing stiffness.

The market for air bearing spindles is expected to reach rise at a CAGR of 7.5 percent during the forecast period. The growing electronic industry as well as favorable economic conditions around the globe are driving the growth of the air bearing spindles market.

MARKET DRIVERS:

The growing applications of air bearing spindle in PCB (Printed Circuit Board) manufacturing is one of the major factor fuelling growth of the air bearing spindles market. PCB manufacturing sector has grown exponentially due to the growing demand for computers, electronic gadgets, LCDs, LEDs, and among others leading towards the positive environment for air bearing spindle market growth. In addition to this, there is upsurge in demand for electronics and optical product due to the emergence of advanced technologies; therefore, the elevated production of semiconductors is witnessed across the globe. Thus, rise in demand for semiconductor & electronics products is anticipated to create numerous opportunities for the manufacturers of the air bearing spindle.

Moreover, surge in sales of the semiconductor products is further anticipated to strengthen demand for air bearing spindle across the semiconductor manufacturing facilities around the globe. For instance as per the studies by UBS, a Swiss multinational investment bank and financial services company, the semiconductor industry revenue is expected to rise 12% in 2022 to about $492 billion. The firm also estimated that the semiconductor industry revenue grew about 7% to $439 billion in 2021. On the other hand, ongoing advancements as well as developments in the air bearing spindle market is consistently broadening the scope and fuelling demand for the air bearing spindle.

Throughout the forecast period, aerostatic air bearing spindle segment will continue to hold a dominant share of global air bearing spindle market on the basis of product type. This is attributed to the increasing adoption of aerostatic air bearing spindle as an essential precision engineering element and technology in several applications that requires precision as well as ultraprecision motions. In addition, to this, due to its benefits such as high rotational speed, low friction, and low motion error, it is widely being applied to high rotational speed and high precision machines. This factor further fuels growth of the segment. However, the aerodynamic air bearing spindle segment is projected to witness highest growth rate during the forecast period.

On the basis of operation, micro machining segment holds a dominant share of global air bearing spindle market in 2021. This is attributed to rise in adoption of air bearing spindle in the micro-cutting processes such as diamond micro-milling, micro-grinding, and raster flycutting to efficiently manufacture optical quality freeform surfaces. However, high precision machining segment is projected to witness highest growth rate during forecast period.
