Twisted 'O' Rings

Twisted 'O' rings/Belting have many different names including quick Connect Twisted belts, connectable belts, quick-fix belts, zero downtime bands, and easy hook round belts. Twisted belting is designed to replace urethane endless round belts that become damaged or worn 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
• Standard Cross sections: 3mm, 4mm, 5mm, 6mm, 8mm, (These are the effective diameters that two strands of twisted cord produce. For example, this means our Twisted 5mm belt replaces a 5mm round o-ring belt)
• Available in many colours
• Durometers 80A to 95A
• Available in Anti-Static (static dissipative)

Critical: Because they are coiled like springs, twisted belts stretch more than round belts. Most round belts are stretched 8-10%, while twisted belts are typically stretched 15%, so twisted belts should be about 7% shorter than the o-ring belts they replace. Also note our SGi tip alongside for small length adjustments.

When ordering we will always supply easy-to-install stainless steel clips with one end fitted.

NEW Abuse Resistant Rough Green Twisted 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.

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.

However, SGi can offer an alternative

As a UK distributor for Superior Bands Inc. of America we can supply there rubber/yarn belts, with some popular sizes from stock. Read the below marketing information from Superior Bands Inc.

After a couple of years and extensive testing we realized that our more natural rope elastic Twisted O-Rings work so much more efficiently and are also more durable than a Polyurethane or a Urethane twisted O-ring. Superior Bands immediately stopped production of Polyurethane belts and focused only on Elastic Rope Twisted O-Rings.

Some of the largest US chemical companies, pharmaceutical companies, warehouse distribution centers and paint companies use our Rope Elastic Twisted O-Rings.

Here are some of the reasons to try our rope Elastic Twisted O-Rings on your line shaft conveyors or roller-to-roller conveyors instead of a Polyurethane belt:

• Our Twisted O-Rings DO NOT POP when you lose power and your facility dips below freezing
• Superior Bands Twisted O-Rings will stretch and go back to their original form unlike Plastic O-rings which, when stretched, stick to the new length
• Our quick connect hook saves time, which equals money, and reduces hazardous risks from trying to use special tools to connect regular o-rings and the noxious gases given off from trying to weld them together
• Less tension with same results....Superior Bands Twisted O-Rings pull less tension on your rollers increasing the life of your roller-to- roller and line shaft roller conveyors while still getting the job done
• Elastic Core
• Faster FPM (feet per minute) times(more product out the door faster)
• Consistent tension on rollers
• More Pulling Power
• Two-Ply Yarn Construction
• Won't freeze and pop during lost power in winter freezes
• More environmentally friendly than polyurethane
