Swivels

Select a swivel based on load direction and motion: single or double swivels for rotation, swivel hoist rings for lifting with angular loads, and marine swivels for corrosion resistance; match working load limit (WLL), swivel orientation, and mounting method to your use case

Choose a swivel with a WLL higher than your maximum expected load and a safety factor appropriate for the application—common industrial safety factors range from 4:1 to 7:1; always check manufacturer-rated WLL and proof/test load specifications

Use stainless steel or zinc/galvanized finishes for corrosion resistance in marine or outdoor environments; carbon steel with durable coatings may be acceptable for indoor industrial uses where corrosion is minimal

Regularly inspect for deformation, cracks, excessive wear, corrosion, and free rotation; lubricate bearings per manufacturer guidance, replace if any damage or loss of rated capacity is found, and keep records of inspections for lifting equipment

Yes—confirm thread size, pitch, and type (UNC/metric) or required bolt/hole dimensions match your equipment; ensure mating hardware meets or exceeds the swivel's WLL and follow recommended torque values

Industrial swivels vary widely by size and capacity; budget options exist under $50, while heavy-duty or certified lifting swivels can cost several hundred dollars, with average prices in this category around $100

Yes—lifting swivels used in certified lifting operations should have traceable load ratings and, where required by regulation, proof load testing, certification, or periodic inspection by a qualified person per industry standards
