Slewing Bearing With Internal Gear Best Value Supplier
The internal gear design significantly saves space and provides natural gear dust protection by integrating the drive structure into the inner ring. It is the core choice for precision rotation of heavy equipment. As a source manufacturer, Slewbearingtec eliminate the cost of middlemen through the whole process of independent production, ensuring that we can provide you with highly competitive ex-factory prices and faster delivery cycles.
Our products
Slewing Bearing With Internal Gear is an indispensable high-load component, which is widely used in engineering and lifting machinery (such as excavators and tower cranes), renewable energy systems (such as yaw and pitch drive of wind turbines) and heavy industrial equipment (such as mine stacker and reclaimer, metallurgical ladle rotary table). Its compact space design and excellent gear protection performance also make it the first choice for precision engineering and special infrastructure, including tunnel shield machines, radar antenna bases and large medical imaging systems.
slewing bearing with internal gear characteristics
Integrated compact space layout
The internal tooth structure allows the motor and drive pinion to be installed inside the bearing ring, saving about 20% of external installation space compared to the external tooth solution.
Excellent gear protection performance
The internal tooth position protects the teeth from direct erosion by external dust, gravel and rain, significantly reducing grease pollution and reducing maintenance frequency under extreme conditions.
High torque smooth transmission
the use of a larger gear contact ratio design, so that the power transmission is more uniform, effectively reduce the impact of equipment start-up and stop vibration, improve the stability of the overall operation.
Tooth surface induction hardening process
The tooth surface is treated by high-frequency induction hardening, and the hardness reaches 50 to 55HRC, which significantly enhances wear resistance, and can extend the service life of the gear for more than 5,000 hours under rated load.
Precision backlash control capability
Through advanced CNC gear cutting process, the gear accuracy is controlled within a very small tolerance range, eliminating the hysteresis in the rotation process, and ensuring that the positioning accuracy reaches the micron level.
Integrated and efficient sealing system
equipped with double lip nitrile rubber sealing ring, to prevent the loss of internal grease at the same time, blocking the outside water vapor into the raceway, to ensure that the core components do not rust in a humid environment.

slewing bearing with internal gear comparison point
The internal gear slewing bearing of the Slewbearingtec ensures the consistency of the depth of the hardened layer through the deep induction hardening technology, which improves the fatigue life of the product by 35% under frequent start-stop impact. In addition, the internal tooth profile optimized by the secondary grinding process can reduce the frictional power loss during gear meshing by about 15%. Compared with the standard models commonly used in the market, the Slewbearingtec pays more attention to the purity control of materials. Each set of bearings has been tested by ultrasonic flaw detection, which completely eliminates the risk of early fragmentation caused by internal inclusions in raw materials. This high-standard quality control combined with the cost advantage of the source factory allows customers to obtain higher performance levels while effectively reducing procurement costs by 10 to 15 percent.

Slewing Bearing with Internal Gear for Crowd
Excavator machine manufacturing engineer
it is necessary to find a high-strength, long-life rotating base for crawler excavators to cope with the continuous impact and high-frequency rotation requirements in harsh excavation environments.
Hoisting Machinery Design Specialist
Dedicated to the development of tower or portal cranes, looking for internal tooth bearings with integrated drive, reduced external maintenance stress and excellent ability to carry overturning moments.
Shield machine research and development procurement manager
responsible for the supply of materials for the core drive module of shield equipment, requires a large diameter inner tooth support with extremely high static safety factor and high reliability sealing performance.
Automated production line integrators
Design large heavy-duty turntables or palletizing robots that require rotary systems with high transmission ratios, low backlash, and the ability to install in tight spaces.
Slewing Bearing with Internal Gear instructions
Installation surface flatness inspection
before installation, ensure that the flatness error of the surface of the support base is less than 0.15mm to prevent deformation of the raceway after bolt tightening.
Symmetrical fastening of high-strength bolts
use a torque wrench to tighten the bolts in three times according to the principle of 180 degree symmetry to ensure that the bearing ring is evenly stressed and has no risk of eccentric load.
Gear meshing backlash adjustment
align the drive pinion with the highest point of the radial runout of the inner ring gear for meshing, and reserve a reasonable backlash to prevent the gear from running stuck.
Periodic lubrication maintenance guide
It is recommended to fill extreme pressure lithium-based grease through the oil filling hole every 150 hours of work, and manually brush and lubricate the tooth surface simultaneously.

the driving device is embedded Slewbearingtec the optimized internal tooth layout, which completely solves the problem that the driving motor cannot be arranged due to the narrow external space, and reduces the overall size of the equipment by 18%.Acceleration of gear wear in dust environment
for open-air operation environment, we use the shielding effect of internal teeth to cooperate with multiple seals to prevent sand and dust from entering the meshing area, and extend the shutdown maintenance cycle caused by particle wear from half a year to two years.Positioning drift under heavy load operation
for long-arm equipment such as cranes, the Slewbearingtec eliminates the virtual rotation position by accurately controlling the matching clearance between the inner gear ring and the rolling element, and ensures that the positioning accuracy error of the long-distance end is controlled within 5mm.Slewing Bearing with Internal Gear for Crowd
