LTZC has achieved a new breakthrough in the manufacturing of crane slewing bearings.

What is a slewing ring on a crane?

Crane slewing bearings are essential components in the operation of cranes, enabling smooth rotation of the crane's boom or platform. These bearings support heavy loads and are crucial in ensuring the accuracy, reliability, and efficiency of crane movements.

At LTZC, a leading slewing bearing manufacturer in China, recent breakthroughs in manufacturing techniques have significantly enhanced the performance and durability of their crane slewing bearings.

Four-point contact ball bearings:

Four-point contact ball bearings are single-row ball bearings, ideal for light-duty cranes. They utilize a single row of steel balls that contact the inner and outer rings at four points. This design allows for high-speed rotation while maintaining stability and handling moderate loads.

Crossed roller bearings:

Crossed roller bearings are used for heavy-duty applications. They feature alternating rollers, providing greater load capacity and higher precision. This type of bearing is preferred for cranes operating in harsh conditions or requiring high load capacity.

Roller bearings:

Roller slewing bearings are designed to handle the heaviest loads, typically featuring a three-row cylindrical roller bearing structure. They are particularly suitable for large crane operations where durability and stability are paramount.

LTZC offers a wide range of slewing bearings for different types of cranes, from compact to large, high-capacity equipment, ensuring optimal performance for every solution.

Why are slewing bearings so important in heavy-duty cranes?

Slewing bearings are often the most critical component in a crane's rotating mechanism. Their primary function is to support the rotation of the crane's upper structure while simultaneously bearing immense radial and axial loads. Here's why they are indispensable:

Precision and Stability:

Precise movement of the crane arm or platform is crucial for safety and operational efficiency. High-quality slewing ring bearings minimize wobble, ensuring smooth and stable operation even under extreme loads.

Heavy Load Capacity:

Cranes are used to lift some of the heaviest loads, so the bearings must be able to withstand these forces. The slew ring must support the weight of the lifted object and the crane itself while maintaining proper function under dynamic conditions.

Long Lifespan and Durability:

Given the harsh operating environments of cranes—often exposed to extreme temperatures, humidity, and dust—slewing bearings need to be highly durable and maintain their integrity over extended periods. A long lifespan reduces downtime and maintenance costs for crane owners.

Precision Engineering:

Crane operation demands precise movements. With advancements in manufacturing technology, slewing bearings are becoming increasingly precise, enabling more accurate movements and greater operational safety.

LTZC has achieved several significant breakthroughs in slewing bearing manufacturing, particularly in the field of crane slewing bearings. The following are LTZC's main innovative breakthroughs:

Large-diameter slewing bearings: LTZC has successfully manufactured large-diameter slewing bearings ranging from 300mm to 13,000mm, suitable for heavy-duty cranes. These bearings can withstand extremely high loads while maintaining high precision, meeting the demands of large-scale equipment.

Enhanced load capacity and durability: By utilizing high-strength alloy materials and advanced heat treatment processes, LTZC's slewing bearings possess higher load capacity and wear resistance, extending their service life and reducing maintenance costs.
