Connectable Belts

DuraBelt Quick Fix connectable belts are also called twisted belting. Connectable belts are designed to replace endless round belts that become damaged or wear out. These connectable belts are easily and quickly installed in the field without dismantling drive shafts. The tips of quick fix belts are loops that you connect together with small stainless steel or plastic hooks that come with the belts.

  • Eliminate costly downtime.
  • No need to drop shafts.
  • Installs in seconds with Speedy Belt Installer (SBI)
  • No need to drop rollers with SBI.
  • Lengths from 2" to 300 ft. (50mm to 100 meters).
  • Measure them from tip to tip, excluding hook.
  • Cross sections: 3/32", 1/8", 5/32", 3/16", 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 9.5mm, 11mm, 12mm, 14mm. (These are the effective diameters that two strands of twisted cord produce. For example, this means our Twisted 3/16" belt replaces a 3/16" round o-ring belt.)
  • Available in many colors.
  • Durometers 80A to 95A.
  • Available in Anti-Static (static dissipative)
Critical: Because they are coiled like springs, twisted connectable belts stretch more than round belts. Most round belts are stretched approximately 10%, while twisted connectable belts are typically stretched 17%, so twisted connectable belts should be about 7% shorter than the o-ring belts they replace.

NEW:   Patented self-crimping stainless steel hook tightly wedges belt loop into hook so no crimping is required. Achieves maximum belt life by eliminating friction between hook and belt loop that ultimately cuts through the loop. Disadvantage -- difficult to install and nearly impossible to unhook if installed backwards, so it must be cut off and thrown away.

When ordering, specify easy-to-install stainless steel, self-crimping stainless steel, or long lasting plastic hooks.

Connectable Round 3/8" (9.5mm) Belts, are used where a twisted belt is too bumpy. When used with large plastic hooks, they are ideal for applications in the glass or film industry, where a broken steel hook might scratch materials or tooling. The 100A durometer loops (red) will not pull out or stretch. Available in any length. The maximum recommended stretch for 83A orange cord with large plastic hooks is 6%.

Abuse Resistant Rough Green Twisted Connectable Belts are harder and have a lower coefficient of friction that lets them slip easier when boxes jam, so there is less heat build up. This means they can take more abuse. Made from 88A cord, their higher tension helps offset their tendency to slip, so they provide almost as much drive as 83A belts. Works exceptionally well on high speed lineshaft curves where belts rub hard and fast against roller grooves. Stretch them 14%. Use only with plastic hooks.

We recommend the Speedy Belt Installer because it greatly reduces the installation time of twisted belts down to about 25 seconds. Click on the picture below to learn more about it.

How to measure Twisted Connectable Belts

Tip -- Twisted connectable belts are adjustable: You can shorten and tighten Twisted Belts by twisting an end before hooking the belt together. One complete revolution shortens the belt by about 1/10 inch. Therefore, if you twist it 5 times before hooking the ends, the belt will be 1/2" shorter and provide greater tension.

Lifespan: Two strands of twisted cord contain about 89% as much urethane as one strand of the round belt that they replace, so they will only last 89% as long, at best. They usually fail when the the hook pulls through the loop. Consequently, twisted belts typically last about 60% to 70% as long as endless round belts.

For the best in twisted belts, false twist drive bands, connectable belts, twisted O-rings, zero downtime belts, and easy hook round belts insist on DuraBelt twisted belting.
