Fabrication Generators Spray Welding Rewinding Happy Thanksgiving


This is an example of an automated oil dispensing tank and pump system that was totally designed and built by A.R.&E. for a local manufacturer...

Generator Install

Here's what an emergency generator installation can look like when A.R.&E. is involved...


Sometimes it's necessary to "buildup" a metal surface that's been damaged by wear. Metalizing is one method of doing just that...


Total rewind of a customer's electric motor. Sometimes, though no one's fault, an electric motor "burns up." That's when our rewind department shines. Here's the technician is rewinding this small motor, and in a couple of hours it'll be "as good as, (or better than) new"...


Turkey and dressing is the classic dinner at this time of year. Thanksgiving Day is an annual national holiday in the United States and Canada celebrating the harvest and other blessings of the past year. The American tradition has us attempting to recreate the dinner between the Pilgrims and the Native Americans. However you celebrate, we at Apparatus Repair & Engineering, Inc. want to wish you all a Safe, Blessed and Happy Thanksgiving.

Flexible Couplings

Jaw Coupling Grid Coupling Chain Coupling
Gear Coupling Disc Coupling Tire Coupling

The "Flexible Coupling" field is the most comprehensive when it comes to shaft couplings.

The pictures above (along with their page links) are certainly the most common, along with a significant number of hybrid within each specific type.

The generally accepted names of the couplings shown are (from left to right and top to bottom):
Jaw Coupling ~ one of the least expensive and highly used types.
Grid Coupling ~ made famous by Falk, it's a heavily used coupling in industry. Requires lubrication.
Chain Coupling ~ the photo doesn't show it but most (if not all) will have a cage around the chain.
Gear Coupling ~ also heavily used in industry. Requires lubrication.
Disc Coupling ~ positive torque transmission and no lubrication.
Tire Coupling ~ flexibility and handles misalignment well.

By clicking on any of the photos, you will be taken to the detail page for that coupling type.

Let A.R.&E. assist you in your selection of the coupling for your next project. And if it requires Laser Alignment (which we recommend for ALL installations), our Field Service technicians are there to service those needs, too.
