Luffing Jib Crane
View system integration details
Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Slewing Ring used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.
A canonical Slewing Ring is characterized by the integration of Inner Ring and Outer Ring. In industrial production environments, manufacturers listed on CNFX commonly emphasize Alloy Steel (e.g., 42CrMo, 50Mn) construction to support stable, high-cycle operation across diverse manufacturing scenarios.
A large-diameter bearing that enables rotational movement between the crane's upper structure (slewing platform) and the fixed base or undercarriage.

Slewing rings are typically manufactured from high-strength alloy steels such as 42CrMo or 50Mn, often case-hardened for enhanced durability and load-bearing capacity in demanding industrial applications.
A complete slewing ring assembly consists of an inner ring, outer ring, rolling elements (balls or rollers), seals to protect against contaminants, and an integrated gear ring for rotational drive mechanisms.
Slewing rings provide the rotational interface between a crane's upper structure (slewing platform) and its fixed base, allowing 360-degree rotation while supporting heavy loads and transmitting torque through the gear ring.
