Slewing bearing
Slewing bearing can simultaneously support larger combined load including axial load, radial load and tilting moment etc. General slewing bearing all has mounting holes, oil holes and sealing apparatus, can meet categories of main machine operating under various different conditions. In addition, slewing bearing possess the characteristics of compact structure, guiding rotation convenient, easy installation and easy to maintenance, and widely applied to large size slewing equipment in the industries of engineering, mining, metallurgy, wind power generation, vessel, seaport, petroleum, chemical industry, light industry, medical appliance, foodstuff, vehicle, robot, aerospace, radar and war industry etc.

Sendzimir mill rolling bearing
This bearing has been specially developed for cold rolling mills of the cluster type, but can also be used for other applications, e.G. Straightening or bending machines. This bearing is a roller bearing has a particularly thick-walled outer ring and can be mounted on stationary support shafts to form back-up or straightening rolls. The forces from the work rolls are transmitted via the support shaft and a system of support saddles to the roll or machine stands. The bearing for cluster mills is produced in many designs but is generally based on double or three-row cylindrical roller bearings. Single row needle roller bearing and
Double row tapered roller bearing designs are also available. The logarithmic contact profile between rollers and raceways produces a vastly improved stress distribution under all load conditions as well as when the bearing is misaligned under load. An optimized finish on all surfaces in contact serves to enhance lubrication conditions. As lubricant is supplied to the bearings via the support shaft, the bearings have lubrication holes and some have one or more annular grooves in the inner ring.

Crossed roller bearing
Crossed roller bearings are thin-wall bearings consisting of an inner ring, a two-part outer ring, cylindrical rollers, and separators. The rollers are oriented at right angles to each other and kept apart by separators. Crossed roller bearings can sustain axial loads in both directions as well as radial loads and strong moment loads. Offering high load capacity within a light and compact envelope, they are widely used in the rotating joints of robots.

Yrt turntable bearing
Rotary table bearing or yrt bearing has an axial component and a radial component, a axial/radial housing washer, a axial/radial shaft washer, a thrust washer, two axial needle rollers and cage assembly and a radial cylindrical roller set which is a full complement or cage-guided. Housing washer and shaft washer have bolt holes for install equally spacer. This kind of bearings has high axial load and radial load, and high tilting rigidity and high precision. This bearing can be sued to the machine tool or other high precision machinery of the rotary table or sub-set, and also can be used for chuck, measuring request higher quality of the parts match it.

Slewing bearing can simultaneously support larger combined load including axial load, radial load and tilting moment etc. General slewing bearing all has mounting holes, oil holes and sealing apparatus, can meet categories of main machine operating under various different conditions. In addition, slewing bearing possess the characteristics of compact structure, guiding rotation convenient, easy installation and easy to maintenance, and widely applied to large size slewing equipment in the industries of engineering, mining, metallurgy, wind power generation, vessel, seaport, petroleum, chemical industry, light industry, medical appliance, foodstuff, vehicle, robot, aerospace, radar and war industry etc.
According to different structural style, slewing bearing can be divided into four point contact ball slewing bearing, cross cylindrical (taper) roller slewing bearing, double row four point ball slewing bearing, double row different diameter ball slewing bearing, ball and roller combined slewing bearing and tri-row cylindrical roller combined slewing bearing etc. Above mentioned slewing bearings can also be divided into different structures of no gear type, external gear type and internal gear type as per if exist gear and gear teeth distributing position.
According to different structural feature, slewing bearing can respectively meet main machine requirements under various load conditions. Among them, four point contact ball slewing bearing has higher dynamic load capacity, cross cylindrical roller slewing bearing has higher static load capacity. Tri-row cylindrical roller combined slewing bearing is a kind of high carrying capacity slewing bearing, due to leading raised carrying capacity to direction of bearing height, various loads can be respectively supported by different raceways and roller sets, so raceway diameter greatly decrease under the same stress condition, it has the character of making main machine more compact.

Tapered roller bearings are designed to take combined heavy radial loads and heavy thrust loads in one direction while operating at moderate speeds. Metric tapers feature a simplified part number for a complete bearing. Inch tapers require a part number for the cup and one for the cone. The difference between the metric and inch tapers is only in the dimensions of measure for the bearings
Backing bearing mainly used for cold cluster rolling mill's roller. This mill take the bearing's outer ring as working surface, generally there's 3 or 5set bearings mounted on each roller and even more, depending on its matching rule. The bearing has thick outer ring and thin inner ring, high accuracy up to abec-7.
Cylindrical roller bearing based on two or three rows of rollers and are available as full complement bearings (without cage) or as caged bearings. The advantage of the bearings without flanges lies in their particularly simple geometrical form and their very high radial load carrying capacity. Cylindrical roller backing bearings without flanges or flange rings cannot accommodate any axial load. So it is necessary to position thrust washers of bronze or plastic between the side faces of the outer ring and the support saddles.
Thrust washers are not required with backing bearings with flanges (or flange rings) as the design of these bearings enables them to accommodate simultaneously acting radial and axial forces.
For different requirement, zsj's backing bearing could fall in 2 classes by material: vacuum-degassed bearing steel and electroslag cemented bearing steel. Combined with advanced heat-treatment, grinding process, the bearing's quality is highly reliable.
