This Geared Slewing Ring integrates precision gear transmission and heavy-duty bearing technology. Through high-hardness quenched raceway and ISO Class 6 precision gear, it realizes smooth rotation and precise positioning under extreme working conditions and has scale supply capacity.
42CrMo alloy steel
Material:
ISO 6 precision milling teeth
Gear accuracy:
HRC 55-62
Raceway hardness:
High strength 42CrMo alloy steel is adopted, which is 20% higher than the tensile strength of ordinary 50Mn material, can effectively resist the huge impact load generated by heavy construction machinery during frequent start and stop, and prevent the ferrule from breaking.
The gear adopts precision tooth milling and grinding technology, the precision reaches ISO 6, and the tooth side clearance is controlled within 0.15mm, which significantly reduces the vibration and noise during transmission, reduces the tooth surface wear speed, and prolongs the service life of the transmission system by 30%.
The raceway is quenched to a depth of 3-5mm, and the hardness reaches HRC 55-62, which greatly enhances the crushing resistance and supports more than 50,000 hours of continuous operation under the rated load.
Equipped with high-performance NBR double lip sealing system, the protection grade reaches IP65, effectively isolating external dust, moisture and debris from invading the internal raceway, extending the maintenance cycle of grease to more than 1000 working hours.
Local induction hardening is carried out on the gear teeth, and the tooth surface hardness reaches HRC 45-50, which effectively solves the risk of tooth breakage at the moment of heavy load start and ensures the structural integrity of gared slewing ring under high torque output.
The surface is sprayed with zinc or epoxy resin coating, and the 720-hour salt spray test is passed to ensure that the product does not produce structural corrosion within 10 years under high humidity and high salt spray corrosion environment such as port machinery or offshore platforms.

This gared slewing ring adopts synchronous integrated heat treatment technology to ensure the perfect balance of gear rigidity and raceway toughness, and its dynamic load capacity is 15% higher than the industry average. By optimizing the design of the rolling element diameter and contact angle, we can reduce the overall structure height and achieve a stronger anti-overturning moment to meet the needs of compact heavy-duty equipment.
In view of the instantaneous impact of heavy machinery, the root fatigue fracture problem that is easy to occur in the traditional toothed slewing bearing is solved by the tooth root strengthening treatment.
The unique labyrinth seal structure and built-in grease tank design are used to solve the raceway wear and frequent grease requirements caused by dust intrusion on the construction site.
strictly control the roundness and position tolerance of the installation hole within ± 0.2mm, thus solving the problems of poor meshing and eccentric wear common to purchasers when assembling drive pinion.
This product meets the strict requirements of engineering machinery for high reliability of slewing mechanism. Its high-strength gear design can withstand severe impact loads during excavation, and is the first choice for core suppliers of mobile machinery such as crawler excavators and truck cranes.
For wind turbine yaw and pitch systems, gared slewing ring provides excellent low speed, high torque carrying capacity, can maintain a stable service life of more than 20 years in outdoor extreme weather, reduce operation and maintenance costs.
Port cranes and ship unloaders need to perform frequent 360-degree operations in salt spray environment for a long time. The anti-corrosion coating and enhanced sealing system of this product can effectively solve the risk of mechanical failure caused by high corrosion and dust at the sea.
For automated assembly lines or large medical imaging equipment (such as CT machines) that require precision indexing and precise positioning, the high-precision gear meshing performance of this product can ensure the rotation accuracy and improve the positioning accuracy of the end actuator.
We mainly use the tooth surface induction hardening process, and the depth of the hardness layer is controllable, which not only ensures the hardness and wear resistance of the tooth surface, but also retains the toughness of the tooth root.
It mainly depends on the spatial layout of the driving mechanism. The external tooth type is easy to maintain and has a large transmission ratio; the internal tooth type has a more compact structure and better protection, which can protect the drive pinion.
Yes. We provide 42CrMo material version after low temperature impact test, and with special low temperature grease, can work in -40 ℃ environment.
Yes. We can provide gared slewing ring with zero clearance or preload processing according to your positioning accuracy requirements to eliminate slewing shaking.
It is recommended to supplement fat once every 100-200 hours under normal working conditions. For extreme heavy load or wet conditions, inspection should be shortened to every 50 hours or weekly.
If only minor scratches can be polished repair, but if there is serious peeling or broken teeth, in order to ensure safety, it is recommended to replace the whole to avoid secondary failure.
