Industrial Bearings FAQS

QWhat is Rotary Table Bearings?

ARotary table bearings are axial and radial combined cylindrical roller bearings, including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial pre-load.

QWhat is Bearings Used in Oil Field Industry?

AWe has been supplying large bearings for oil field drilling exploration for a long time. Types of equipment are mud pumps, swivels, drawworks, crown and traveling blocks, rotary table, blow-out preventers, and well service pumps. Usually, large cylindrical roller bearings with thin cross sections are used. Rotary tables use large thrust angular contact ball bearings. Mud Pumps Service Pumps Drawworks Swivels Rotary Tables

QWhat is slewing bearing?

ASlewing bearing is a kind of large-scale bearing that can bear comprehensive load, and can bear large axial, radial load and overturning moment at the same time. Generally, the slewing bearing is equipped with mounting hole, internal gear or external gear, lubricating oil hole and sealing device, so that the design structure of the main engine is compact, the guide is simple and the maintenance is easy. There are four series of slewing bearing, namely, four point contact ball bearing, double row angular contact ball bearing cross cylindrical roller bearing, cross tapered roller bearing and three row cylindrical roller composite bearing. Four point contact ball bearing has higher static load capacity, cross cylindrical roller has higher dynamic load capacity, and cross tapered roller bearing pre load capacity. The interference can make the bearing have greater support rigidity and rotation accuracy. Due to the improvement of bearing capacity, the three row cylindrical roller composite bearing is oriented to the bearing height, and various forces are respectively borne by different raceways. Therefore, under the same stress, the bearing diameter can be greatly reduced, which makes the main engine more compact. It is a kind of high bearing capacity slewing bearing. Slewing bearing is widely used in large-scale slewing devices of hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery, high-precision radar machinery and missile launcher. At the same time, we can design, develop and produce all kinds of special structure slewing bearing according to the specific requirements of users.

QWhat is the turntable bearing application?

ASlewing ring(turntable bearing) is widely used in the real industry, which is called "the joint of machine". It is mainly used in automobile crane, railway crane, port crane, marine crane, metallurgical crane, container crane, excavator, filling machine, as well as CT standing wave therapeutic apparatus, navigator, radar antenna base, missile launcher, tank. Robot, revolving restaurant and so on.
