Round Belts
Made of polyurethane, these belts resist chemicals and abrasion. Also known as O-ring and endless belts, they come ready to use.

Static-Control Round Belts
Made of a specially formulated polyurethane, these belts prevent the static buildup that could damage sensitive equipment in your setup. Their surface resistivity won’t decrease as the belts age, stretch, or are exposed to low humidity. Because they’re polyurethane, they also resist chemicals and abrasion. They come ready to use.

Low-Temperature Round Belts
Made of hytrel polyester, these belts can be used in lower temperatures than standard polyurethane belts without becoming brittle. They’re ideal for refrigerated and cold rooms. However, their surface will wear from repeated friction quicker than polyurethane belts, and they won’t bounce back if overstretched. They come ready to use with your system.
Note: The maximum recommended stretch for these belts is 7.5%.

Chemical-Resistant Made-to-Order Round Belts
In addition to chemical resistance, these belts also provide increased abrasion resistance over heavy duty round belts. Also known as O-ring and endless belts, they come ready to use.
To Order: Please specify outer circumference in 1/4" increments.

Heavy Duty Made-to-Order Round Belts
These belts are reinforced with a polyester cord for strength. Also known as O-ring and endless belts, they come ready to use.
To Order: Please specify outer circumference in 1/4" increments.

Quick-Hook Twisted Round Belts
Install these belts without dismantling your drive shafts—hook the ends together with the attached stainless steel connector.
Installer kits include a holding tool to keep one end of the belt in place, a gripping retriever to loop the belt around your pulley, and a hooked tool for pulling the belt loop over the connector.
Optional plastic connectors can be used instead of the included stainless steel connector.

Round Belting
This belting has a smooth, easy-to-clean surface. Good for light duty conveying and power-transmission applications, it is chemical and abrasion resistant and creates stronger connections than hollow-core belting. Join the ends with round belting connectors (sold separately) or use a welding kit.

Heavy Duty Round Belting
This polyurethane belting is reinforced with a polyester cord for strength. Good for light duty conveying and power-transmission applications, it is chemical and abrasion resistant and creates stronger connections than hollow-core belting. Join the ends with round belting connectors (sold separately) or use a welding kit.

Quick-Connect Hollow-Core Round Belting
The hollow core of this polyurethane belting allows you to join the ends without trimming, welding, or using special tools. Good for light duty conveying and power-transmission applications, it is chemical and abrasion resistant. Join the ends with quick-connect hollow-core round belting connectors (sold separately).

Extended-Life Leather Round Belting
More elastic than polyurethane, this leather belting resists permanent stretch for a long service life. Join belting ends with connectors (sold separately).
Joining tool cuts belting, punches holes for connectors, and secures connectors to belting ends.

Ultra-Flexible Round Belting
Coiled-metal construction provides flexibility to bend around small-diameter pulleys and accommodate curved belt drives and misaligned pulleys. Cut belting to the length you need, thread connectors (sold separately) onto each end, and hook them together.
Stainless steel belting is corrosion resistant for use in harsh environments.
