Although its basic performance is similar to that of deep groove ball bearing, most of the bearings are used in relatively rough machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole is neutral, or the shaft is long and the deflection is large, and the accuracy of the bearing itself is not high enough, and some structures are relatively rough, so the actual performance of the bearing is relatively the same specification Deep groove ball bearings are subject to considerable discount.
Stone pattern metal carving board is not only suitable for the new brick concrete structure, frame structure, steel structure, light weight house and other types of buildings, but also suitable for the decoration and energy-saving transformation of existing buildings, as well as indoor and outdoor decoration.

6304-2RS (I.D.=20mm, O.D.=52mm, Thickness=15mm); 6304-2RS bearing are shielded on BOTH SIDES to keep lubricant in; Chromium Steel long-life bearings, smooth and low noise.
There are no overlaps, gaps or gaps in the OSB boards. The finished panels are available in large sizes, minimizing the number of joints that may "leak" heat and allow airborne noise.
The lightning protection grounding lug is a lightning protection grounding component that collects the static electricity on the photovoltaic module and the photovoltaic support into the ground through the grounding copper wire.
Solar microporous aeration is a kind of water treatment system specially designed for water purification and water quality improvement of rivers and lakes.The use of solar energy as a power source, with low operating management cost, good effect of oxygen, large flow, anti-blocking, long life, low operating noise characteristics.Widely used in urban river, artificial lake, natural lake;Suitable for aquaculture, fish pond oxygen;In the practice of water body restoration, it has obvious effects on water body reoxygenation and water body circulation.
