The 133.45.2150 slewing ring adopts a reinforced structural design tailored for crawler crane lifting conditions, delivering outstanding resistance to axial load, radial load, and overturning moment. Its compact structure reduces the overall weight of the rotating assembly without compromising load capacity, perfectly matching the lightweight design requirements of modern 150-ton crawler cranes.
Precision machined raceways and high-precision gear teeth ensure smooth, jitter-free rotation during lifting operations, even under full load conditions. This stable rotation performance significantly improves the positioning accuracy of heavy lifting, reduces vibration during operation, and extends the service life of adjacent components of the crane.
Manufactured with high-quality alloy steel and strict heat treatment processes, this slewing bearing offers excellent wear resistance and impact resistance. It can maintain stable performance in harsh outdoor construction environments, including temperature fluctuations, dust, and rain, reducing maintenance frequency and long-term operating costs for industrial business clients.
This 150-ton crawler crane slewing bearing is primarily designed for 150-ton class crawler cranes, and is widely compatible with mainstream crawler crane models of the same tonnage. Its application scenarios cover heavy lifting operations for bridge and highway infrastructure construction, wind power equipment installation and hoisting projects, petrochemical and large-scale industrial equipment hoisting, and urban high-rise building construction. It is the preferred core component for crawler crane original equipment manufacturers, heavy equipment rental companies, and engineering construction contractors.
To ensure optimal performance and service life of the 133.45.2150 slewing bearing, follow these core guidelines:
Installation: Clean the mounting surface thoroughly to ensure flatness and no foreign matter; tighten mounting bolts diagonally according to the specified torque, and use qualified fasteners that meet strength requirements.
Operation: Avoid overloading and sudden impact rotation during operation, and strictly follow the crane's rated load specifications to prevent damage to the bearing raceway and gear teeth.
Maintenance: Perform regular lubrication of the raceway and gear teeth according to working conditions; check bolt torque and bearing sealing condition every 500 working hours, and replace damaged seals in a timely manner to prevent dust and impurities from entering the raceway.
We provide comprehensive customization and bulk procurement solutions for construction machinery manufacturers, maintenance service providers, and engineering contractors. Our customization services include adjustments to mounting hole layout, gear parameters, material grades, and surface treatment processes to meet your special matching needs for non-standard equipment. For bulk procurement, we offer competitive wholesale pricing, stable production lead times, and dedicated technical support, ensuring a reliable supply chain for your mass production or long-term equipment maintenance inventory needs.
The standard model is designed for mainstream 150-ton crawler cranes, and we can provide customized modifications to the mounting structure and gear parameters to achieve full compatibility with different brands of the same tonnage crawler crane models.
In conventional construction environments, lubricate the raceway and gear teeth every 500 working hours. For harsh working conditions such as high dust, high humidity, or continuous heavy load operation, shorten the lubrication cycle to 250 working hours.
This 150-ton crawler crane slewing bearing is engineered to withstand combined axial load, radial load, and overturning moment simultaneously, which fully meets the complex load requirements of crawler crane lifting, luffing, and rotation operations.
