Lifting synthetic Slings available at Baremotion

Nylon Synthetic Web Slings and Polyester Synthetic Web Slings are extremely popular rigging items. Both have the same lifting capacity - So which to choose and which is better?

There is no clear answer! It depends on the application, the environment, the usage, and so on. Below we try to break down the tiny differences and the similarities.


At Baremotion, we have partnered up with major rigging houses in the industry allowing us to provide our customers with top quality products.

All our Synthetic Web Lifting Slings are Made in USA.

Nylon web slings and Polyester web slings come in the same styles, the most popular ones being Type III (Flat Eye & Eye Slings) and Type IV (Twisted Eye & Eye Slings). These Eye & Eye Web slings are Made with a loop eyes on the end of each body. Either a Flat loop or a twisted loop.
Both can be used in all three hitches - Vertical, Basket, and Choker - but the Type IV Twist Eye & Eye web slings is mostly recommended for the choker hitch a



These synthetic slings both come in the same common widths: 1" wide web sling, 2", 3", and 4" wide web sling (larger sizes are available). The larger the ply - at Baremotion we supply 2-Ply standard web slings, larger ply is available upon request - (and length), the larger the lifting capacity of the sling.

Web Slings are lightweight, flexible, and durable. They can adjust and conform to grip and mold to irregular loads.
They are not bulky and due to their flat design can be easily slide under loads.

Both materials have a design factor of 5:1 - meaning the breaking strength of the sling is 5 times higher than the rated working load limit. Never exceed the rated WLL!

Temperature wise not materials most not exceed 194 F (Fahrenheit) or below -40 F (Fahrenheit).


Nylon & Polyester have the same lifting capacity. BUT Polyester Web Slings have less stretch. They stretch to 3%, while Nylon synthetic web slings stretch to 10%. Depending on your usage and the application you might want more or less stretch! The less stretch is better for load control, while the more stretch helps avoid shock loading. 

Polyester web slings are more cost effective.

Chemical Environment differences:

Some chemicals have adverse effects on Nylon & Polyester.
Nylon - Should NOT be used in environments that have Acids & Bleaching Agents.
Polyester - Should NOT be used in environments that have Ethers & Aldehydes (Alkalis).


Use & Safety Considerations:

- Avoid prolonged exposure to sunlight & UV rays as they can weaken the strength of the sling.

- Make sure Tag is not missing and is always readable - OSHA requirement.

- Inspect before usage.

- To prevent damage sling should avoid contact with protrusions during lifting, storing, or transport.

- Make sure there are no broken stitching, knots, abrasions, color fading, or cuts. If there are the sling must not be used and taken out of service.

- Red core yarn comes in each sling. It’s an additional aid to warn of sling damage. The red thread becomes exposed when the sling is worn or cut.

- Wipe down & store slings in dry cool place for longer life service.


All Lifting Slings come with label that includes size, type, and capacity information. We also supply other lifting products such as Polyester Round Slings and Chain Slings.

Lifting accessories such as shackles.
