The strength of the connection can be improved with suitable adhesives. Back-up washers are also recommended for distributing load stress. When drilling, make sure you use a drill that makes a hole slightly larger than the diameter of the rivet.

First ball bearing

The strongest joint between composites is created by properly fitted bolts and applying adhesives to the prepared mating surfaces.

For removable cover plates, sheet metal screws can be used. The strength of the connection can be improved by using threaded inserts and bonding them into place with adhesive.

In corrosive environments, stainless steel or Monel screws should be used, unless a suitable polyester/epoxy coating is applied to exposed screw heads.

Some types must be bonded in place while others can be mechanically fastened. Please refer to manufacturer’s instructions in each case.

We recommend Emhart POP® rivets. These are available in various sizes and head styles in aluminum, steel, Monel, copper and stainless steel.

Thrust bearing

When bolts are to be installed permanently, a tight connection can be made by tapping the composite and applying epoxy or polyester adhesive to the hole just before inserting the bolt.

A common method for installing removable bolts is to tap your composite product and apply epoxy or polyester adhesive in the hole. Next, cover the threads and shank with a releasing agent and insert the bolt.

Leonardo da Vinci invented the ball bearing around the year 1500. He designed it to lower the friction between two plates that would be in contact in his other famous design for the Helicopter. The first known discovery of a ball bearing type device was found in the Roman Empire in the form of a simple rotating table with balls underneath, presumably to allow the people eating at the table to simply rotate the table to get to the food at the other side of the table. It wouldn’t be until 1792 that there was a patent filed for the “modern” ball bearing by the Englishman Philip Vaughn.
