The attention is second only to the angular contact ball shaft and the coaxial heat exchanger. It is a high-precision bearing and an imported bearing for the machine, accounting for 17% and 13% respectively. Imported bearings are limited to relative domestic bearings.
In addition to the coaxial heat exchanger, buyers are also concerned about the angular contact ball axis, accounting for 26%. It can withstand both radial and axial loads. The larger the contact angle, the higher the axial load carrying capacity.
As can be seen from the figure, the coaxial heat exchanger became the most popular search term in June, accounting for 28% of the total bearing products. The product is mainly composed of concentric inner tube and outer sleeve. It has high safety and good manufacturability and is not easy to leak. It is especially suitable for heat pump systems.
In the buyer's search, bearings, couplings and outer spherical bearings also accounted for a certain proportion, accounting for 7%, 5% and 4% respectively.
