Atra-Flex offers all these advantages:
Now there's a new solution to one of the most persistent and troublesome problems facing maintenance personnel - periodic coupling failure and the downtime and expense that go with it. If a new insert is needed, a low-cost replacement can be installed in minutes without moving either the prime mover or the driven equipment. There are only four parts in ATRA- FLEX couplings. The two identical hubs (number 1 and 2, right) are made of steel, each with four, six or eight teeth, depending on load and size. The split insert (Number 3), which is made of specially compounded polyurethane, fits between the hubs. The outer steel holding ring (Number 4) has no nuts or bolts!
Changeout of coupling insert is faster than any other.
Custom compounded polyurethane inserts provide elasticity and resistance to high torque, shear and shock loads.
Unlike others, a single ATRA-FLEX coupling can be purchased to fit two different shaft sizes.
Elastic insert is highly resistant to humidity, oils, corrosion and chemicals; retains performance characteristics at temperatures from -60 degrees F to +200 degrees F
No lubrication or service is required.
ATRA-FLEX couplings have run 70,000+ hours with no signs of wear.
ATRA-FLEX couplings may be installed horizontally or vertically; can rotate in either direction.
No bolts or sharp edges provide safer operation.
Operation is completely silent at all speeds and loads.
No metal-to-metal contact between coupling parts.
Initial cost is low, and maintenance and downtime are minimal.
High temperature insert (red) available to +350 degrees F.
Assembly and Disassembly:
After hubs (1) and (2) and holding ring (4) are installed on shafts, the teeth are then aligned parallel to each other, but not touching. Once installed, the hubs never need to be moved again. The elastic insert (3) can then be installed in the slots formed by the parallel teeth. When the insert is in position, slide holding ring (4) onto the polyurethane insert starting, centrifugal force will expand the elastic insert to fix it tightly to the inside of the steel ring.
To disassemble, remove the ring. The insert can then be quickly and easily removed and replaced. No special tools, screws, bolts or other fasteners needed.
