Segmented Track

Segmented track is a precision track assembly designed specifically for large slewing bearings or slewing rings. Bolted together, the segments ensure high-precision raceway matching and load-bearing capacity, while also facilitating transportation, installation, and maintenance. Widely used in construction machinery, wind power generation, port machinery, and heavy equipment, they are key components for achieving smooth rotation and highly reliable operation of large equipment.

LTZC Segmented track advantages

Suitable for Ultra-Large Diameter Equipment

LTZC segmented track enable the assembly of large-diameter structures ranging from Ø 3m to Ø 20m+, breaking through the limitations of full-circle machining dimensions. They are particularly suitable for wind power, port equipment, marine platforms, and large rotating structures.

High-Precision Segmented Machining and Assembly Control

Utilizing LTZC's five-axis machining center and CNC gear grinding equipment, the end face, gear profile, and hole tolerances of segmented rails can be maintained within ±0.02–0.05 mm, ensuring overall roundness and meshing accuracy after assembly.

More Convenient Transportation and Construction

LTZC's segmented track design significantly reduces transportation difficulty and hoisting complexity, allowing for rapid on-site assembly. Transportation costs are reduced by 20%–40% compared to full-circle structures.

Stable Structure and High Strength

Using LTZC's proprietary material system and heat treatment process, each rail segment has a uniform hardness distribution (typical surface hardness 55–62 HRC), with overall strength and lifespan consistent with full-circle rails

Reduced Maintenance Costs: When localized wear occurs, individual track sections can be replaced as needed, eliminating the need for complete disassembly and significantly reducing downtime and maintenance costs.
