LTZC Delivers Precision-Manufactured Gear Shafts and Slewing Bearings

LTZC  Precision-Manufactured Gear Shafts and Slewing Bearings 

As a trusted slewing bearing manufacturer, LTZC once again demonstrates its expertise in precision manufacturing by successfully delivering a batch of custom gear shafts and slewing bearings for a heavy-duty transmission project. These components are designed to provide high load capacity, superior rotational accuracy, and long-term reliability under demanding conditions.

High-Precision Gear Shafts for Heavy Machinery

The supplied gear shafts feature optimized tooth geometry and uniform surface finishing, ensuring stable torque transmission and reduced vibration during operation.

Each shaft is produced from 42CrMo alloy steel, heat-treated for enhanced hardness and fatigue resistance. The machining accuracy reaches ISO 6–7 grade, and the surface roughness is controlled below Ra 0.8 μm, meeting the performance standards required in excavators, shield tunneling machines, and industrial gearboxes.

Product Highlights:

Material: 42CrMo / 40Cr

Gear Module: M10–M20

Hardness: HRC 55–60

Precision Level: ISO 6

Application: Transmission systems, slewing drives, and industrial machinery

Customized Slewing Bearings with Enhanced Load Capacity

In addition to gear shafts, LTZC supplied slewing bearings tailored for the customer’s rotary equipment. These bearings are capable of withstanding axial, radial, and overturning moments simultaneously — a critical requirement for large-scale construction and lifting machinery.

The bearings adopt a cross roller structure for increased rigidity and smoother rotation. Each unit undergoes strict quality inspection including ultrasonic flaw detection, raceway hardness testing, and gear accuracy verification.

Slewing Bearing Specifications:

Outer Diameter Range: 500mm–6000mm

Structure: Cross roller / Three-row roller

Gear Type: Internal gear / External gear / Non-gear

Raceway Hardness: HRC 55–62

Application: Cranes, wind turbines, shield machines, automation systems

Precision Manufacturing and Global Supply

All LTZC products are produced in a fully digitized workshop equipped with CNC turning, gear hobbing, grinding, and automatic assembly lines. Strict traceability and real-time inspection ensure every gear shaft and slewing bearing meets global standards before delivery.

With advanced precision manufacturing capabilities and flexible customization options, LTZC provides slewing bearings for sale to customers across Europe, Asia, and North America, supporting industries such as construction machinery, energy equipment, and intelligent automation.
