What Is a G80 Swivel Self-Locking Hook?

G80 swivel self-locking hooks are essential components in chain sling systems, offering high safety through automatic locking and improved handling through swivel rotation. One key design difference is whether a bearing system is integrated into the swivel mechanism, which directly affects rotational performance during lifting operations.

Structural and Performance Differences

Non-bearing swivel self-locking hooks rely on direct metal-to-metal contact to allow rotation. Their structure is simple and robust, making them suitable for general lifting applications where rotation under full load is not critical.

Bearing-type swivel self-locking hooks incorporate thrust bearings or ball bearings within the swivel joint. This design significantly reduces friction and enables smooth rotation even under heavy load, helping to minimize torsional stress on chains and improve efficiency during load positioning.

Typical Applications and Selection Guidance

Both bearing and non-bearing G80 swivel self-locking hooks meet Grade 80 strength and safety requirements. The primary difference lies in rotational performance rather than load capacity.

Non-bearing hooks are commonly used in standard industrial lifting and cost-sensitive projects. Bearing-type hooks are recommended for precision lifting, frequent repositioning, and applications where controlled rotation is required.
