IKO Cross Cylindrical Roller Bearing FAQS

QWhat is Turntable bearing?

ATurntable bearing (also called slewing bearing) is a kind of large-scale bearing with special structure that can bear large axial load, radial load, overturning moment and other comprehensive loads at the same time. It integrates multiple functions such as support, rotation, transmission, fixation and sealing, corrosion prevention, etc. it is a product with high technology content and high added value, widely used in lifting machinery, engineering machinery, transportation. Machinery, mining and metallurgical machinery, medical equipment, as well as ships, radars, wind turbines and other equipment.

QWhat is Rotary bearing factory?

AAt present, there are many manufacturers that can produce the rotary table bearing. Foreign companies mainly include: rotherde in Germany. Company and fag, ROLLIX in France, taperex in the UK, Rui Dian's SKF company, etc. Our country began to produce and apply turntable bearings in 1960s. Domestic production The main manufacturers of turntable bearings are Luoyang LYC bearing Co., Ltd., Wafangdian Bearing Group Co., Ltd., and Luote idehui, Xuzhou. Rotary bearing Co., Ltd., Ma'anshan square circle Rotary Bearing Co., Ltd.

QWhat is types of rotary table bearings?

AThere are many types of rotary table bearings, including: four point contact ball rotary table bearing, double row reducing ball rotary table bearing, cross cylindrical roller rotary table bearing, cross tapered roller rotary table bearing and three row cylindrical roller combined rotary table bearing. It can also be divided into toothless type, external type and internal type according to whether it has teeth and the distribution of teeth. According to different structural characteristics, the bearing of rotary table can meet the requirements of main engine under different load conditions. Among them, the four point contact ball turntable bearing has a higher dynamic load capacity, the cross cylindrical roller turntable bearing has a higher static load capacity, the cross tapered roller turntable bearing's pre interference can make the bearing have a greater support rigidity and higher rotation accuracy, the three row cylindrical roller combined turntable bearing due to the bearing capacity to the bearing height direction, various loads It is also borne by different raceways and roller groups, so its bearing diameter can be greatly reduced under the same stress conditions, so it has the characteristics of making the main engine more compact, and it is a kind of high bearing capacity turntable bearing.

QHow to measure the axial clearance?

APlace the reference end face of one ring of the bearing on the three equal fulcrum or large platform, and place three measuring meter racks equidistant along the circumference. The head of the meter rack refers to another ring. During the measurement, the three adjustable supports at the same distance of the lower circumference shall slowly and evenly contact the end face of the non supported ferrule and gradually jack up until the end face of the original supported ferrule leaves the large platform. At this time, the arithmetic mean value of the movement indicated by the probe, i.e. the axial clearance value of the bearing
