Open Housing Slewing Drive
Open housing slewing drive features
Open structure design: Easily maintains daily maintenance, lubrication, and inspection, reducing maintenance costs.
High-precision slewing bearing: Ensures stable positioning accuracy during long-term operation.
Strong load capacity: Capable of withstanding axial, radial, and tilting forces, adapting to various operating environments.
High compatibility: Flexible installation in various rotating machinery and automation equipment.
Open housing slewing drive advantages
High-strength materials meet heavy-duty performance requirements.
LTZC open slew drive mechanisms are manufactured using 42CrMo hardened and tempered steel (hardness HB 260–320) or 50Mn carburized steel (hardness HRC 58–62), ensuring excellent wear resistance and long-term durability under continuous torque loads.
Optimized load-bearing capacity
Thanks to LTZC's advanced precision raceway machining process, the open slewing drive achieves the following performance: static load: 300–950 kN, dynamic load: 120–650 kN, overturning moment: 4.5–22 kNm, providing excellent load distribution and reliability for the drive equipment.
Precision Gear Machining
LTZC employs five-axis machining and precision grinding processes to achieve: gear accuracy grade 7–8 (GB/T 10095), backlash control: 0.10–0.25 mm, smoother meshing, lower noise, and high torque transmission efficiency.
Corrosion Resistant and Environmentally Friendly
LTZC's open slewing drive utilizes a zinc-nickel coating (≥720 hours salt spray test) and special lubrication to maintain stable torque output even in harsh environments.
Applications
Construction Machinery: Concrete pump trucks, drilling rigs, mast cranes, mini crane platforms
Security Monitoring and Radar Systems: Servo motors, speed reducers, radar antennas, optoelectronic pods
Marine and Offshore Equipment: Offshore work platforms, deck machinery, mini cranes
New Energy and Environmental Protection Equipment: Biomass processing systems, wind direction adjustment mechanisms
