As a high-performance representative of four-point contact ball slewing bearings, the PLU32 series is designed to handle demanding operating conditions. It not only integrates all the core functions of a slewing bearing but also achieves breakthroughs in design, enabling it to demonstrate exceptional advantages in handling a wide range of load types.
1. Excellent Load Capacity: One Shaft for Multiple Uses, Efficient and Reliable
The core advantage of the PLU32 series lies in its unique design. It can simultaneously support axial loads, radial loads, and overturning moments. Within a single four-point contact ball slewing bearing, two V-shaped raceways and four contact points effectively distribute and transmit forces. This eliminates the need for multiple bearing combinations to address complex load conditions, simplifying equipment design, reducing costs, and significantly improving system reliability.
2. Precise Rotational Performance: Stable Operation and High-Precision Positioning
To ensure smooth equipment operation, the PLU32 series utilizes high-precision manufacturing processes. Its internal raceways and steel balls are precision machined and heat-treated, ensuring extremely low friction and excellent rotational accuracy. This is crucial for applications requiring precise positioning, such as construction machinery, lifting equipment, wind turbines, and robotic joints.
3. Compact Design: Space-Saving and Easy Integration
Compared to traditional bearing combinations, the PLU32 series slewing bearing's compact design offers greater flexibility in overall equipment layout. Its reduced installation space requirements make it easily integrated into a variety of complex mechanical systems, making it particularly suitable for compact equipment with stringent space requirements.
4. Excellent Durability and Long Life
We understand that long-term, stable equipment operation is of paramount importance to our customers. The PLU32 series is constructed of high-quality alloy steel and undergoes rigorous quality control. Its optimized lubrication system and sealing structure effectively prevent the ingress of external contaminants such as dust and moisture, significantly extending the service life of the four-point contact ball slewing bearing and reducing maintenance frequency and costs.
The versatility and high performance of the PLU32 series slewing bearing make it widely used in a wide range of applications:
Construction Machinery: Rotating platforms of large equipment such as excavators, cranes, and tunnel boring machines.
Lifting Equipment: Slewing mechanisms in port cranes, tower cranes, and other equipment.
Automation and Robotics: Bases and joints in industrial robots, enabling precise rotation and positioning.
New Energy Equipment: Yaw systems in wind turbines, ensuring blades are precisely aligned with the wind.
Medical Equipment: Rotating components in large medical scanners.
