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.
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 manufacturing process, china slewing ring gear, Fenghe Slewing bearing provide different kinds of surface treatment: Such as Zinc coating, Sand blast, Painting, oil protecting, barffing etc, which will guarantee the slewing bearing with long durability.
Each type of slewing bearing corresponds to a load-bearing capacity curve, which can help users make preliminary selections of slewing bearings. There are two types of curves in the graph. One is the static load curve, which represents the maximum load that the slewing ring can bear when it remains stationary. The other is the limit load curve of slewing bearing bolts, which is determined when the clamping length of the bolt is 5 times the nominal diameter of the bolt, and the pre-tightening force is 70% of the yield limit of the bolt material.
Slewing ring turntable,Slewing ring bearing with external gear, High speeds, high loads and salty environment require strong and precise components. The Fenghe slewing rings is the perfect answer to the offshore industry.
The without teeth slewing ring transmits loads from a turning part towards the fixed part of a mechanism. The applied stresses of the rolling elements on the raceways are calculated according to the Hertz laws and the modern criteria of plasticity. Fenghe carries out localized hardening treatments which makes it possible to satisfy these criteria just as well in terms of surface pressure as well as subsurface fatigue.
