Note:
- Ball & Roller combined slewing bearing is applied for heavy axial loading, the eccentric rate(e) less than 1.2 and continuous rotating and long life.
- Refer to Table A if slewing bearing are stuck with double row sealing; Refer to Table B if slewing bearing are with labyrinth seal.
- If you need more information about the structure please contact with us.
- The gear torque is under atmosphere of Q&T
The slewing bearing is an important part of the excavator. In simple terms, in addition to the role of "connecting up and down", it is more important that it is the basic guarantee for the excavator to rotate 360 degrees.
Due to the different working conditions of slewing bearings, most of them work under eccentric load. In addition to bearing axial load and radial load, the bearing must also overcome the effect of overturning moment. Therefore, the bearing selection calculation is based on the load-moment diagram. The curve is the method commonly used by major manufacturers at present as the selection method of slewing bearings
Slewing bearing price, High speeds, high loads and salty environment require strong and precise components. The Fenghe slewing rings is the perfect answer to the offshore industry. Our specific design satisfy the main manufacturers of onboard and harbour cranes, winches, davits and rubber tired gantry cranes as well as propellers. We propose innovative solutions of sealing to completely protect the bearings from the environment. fenghe follows the international certification standards.
China Slewing Ring Bearing Manufacturers, Excavator Slewing Bearing, For the slewing ring manufacture, Fenghe selects the best material specifications to suit most foreseen usages.These materials are manufactured by approved steel works.
According to different structural types, Fenghe slewing bearings can be divided into four-point contact ball slewing bearings, double-row angular contact thrust ball slewing bearings, crossed cylindrical roller slewing bearings, crossed tapered roller slewing bearings, and three-row cylindrical roller combined slewing bearings. The above-mentioned various types of bearings are divided into different structures such as gearless external gear or internal gear according to whether they have teeth and the distribution of gear teeth.
The double rows ball slewing ring consists of two parts slewing rings, which can withstand large axial loads, radial loads and titling moments, and has a higher safety factor. It is widely used in medium and large cranes, mining equipment, excavators and other mechanical equipment.
Stacker reclaimers, tunnel boring machines and excavators are very demanding applications. The high capacity of the Fenghe slewing rings is obtained by the control of the hardening process of the raceways and the gears. Our logistic department supplies our product everywhere in the world even large diameter slewing rings.
Forest and de-barker machines require strong components. Our finishing by grinding brings a valid pre-loading which is very important for the life time of the slewing bearing and the comfort of the forest machine’s drivers. Our slewing rings accept the shocks and the high rotating speed of the de-barkers as well as the temperature of the coldest forests.
