The rollers are symmetrical, the inner ring has no middle ribs and no end ribs. The cage is split. The material is a stamped steel frame cage. A movable intermediate ring is designed between the roller and the roller. Its function It can effectively reduce the internal friction of the bearing, can effectively assist the rolling elements in the non-stressed area to enter the load area correctly, and also increase the limit speed of the bearing.

Bearing of reaction crusher

• High efficiency reaction crusher,mainly used in the second and third level fine crushing process,high crushing efficiency,high efficiency and energy saving.

• JRZC R&D design CC and CA spherical roller bearings to support corresponding crushers.

Feature

• JRZC use high purity vacuum degased bearing steel as raw materials,so as to ensure bearing quality from the very beginning.

• Aichelin salt bath heat treatment for the ring and rollers contribute to stable quality.Hardness difference of one bearing rings and rollers is less than 1HRC,30% higher request than the normal GB/T 34891-2017 standard.

Details

	High quality steel Xingcheng steel Precise grinding treatment of bearings to reach P5 level.		High temperature resistant and tough cage The cage is manufactured using FAG technology to make the bearing more resistant to high temperatures and enhance toughness.
	The outer ring of P5 grade, Precise grinding treatment 3 times to reach P5 grade		Precise treatment of oil holes to extend bearing life Precise grinding treatment 2 times,Smooth surface without burrs to extend bearing life.

Compared with the CA structure, the tensile strength of the CC type cage has been greatly improved. At the same time, because the CC structure design occupies less internal space of the bearing than the CA structure design, the number of rolling elements is increased and the shape of the rolling elements is changed. The size, which can improve the radial bearing capacity of the bearing to a certain extent, so it can withstand a larger axial bearing capacity than the CA structure design.

Application

It is mainly used in high-efficiency impact crushers in the secondary and tertiary fine crushing industries, as well as mining machinery, crushers, gear boxes, steel rolling conveyors, reducers, rolling mill tension rollers, etc.
