Most of the flexible shaft couplings on the market today are either partially, or entirely, made of metal. Since metal is such a good electrical conductor it can be a challenge for the design engineer to find a suitable product to serve as a flexible coupling for transmitting torque and yet not transmitting electrical current.

When a pressure is exerted anywhere in a confined incompressible fluid it is transmitted equally in all directions throughout the fluid. In fact the pressure ratio (initial difference) remains the same throughout the fluid. This principle is successfully used in the range of ETP products...

The Jaw style shaft couplings from Abssac are a low cost, no fuss flexible shaft connection...The curved jaw coupling design consists of an elastic ‘spider’ and two hubs. The spider utilises advanced polyurethane materials to provide reliable torque transmission as well dampening of impulse loads.

Another shaft coupling connection challenge was successfully solved by the Helical flexible beam product available through Abssac Limited. Abssac's customer had an application where a precision encoder was being connected to a carpet manufacturing machine output shaft.

ABSSAC continues the sponsorship of the TDMS Robotics club at The De Montfort School into 2017 and wishes them luck with preparations for the next regional event. The VEX Competitions, tasks teams of students with designing and building a robot to play against other teams from around the world in a game-based engineering challenge.

The low friction within ball screw designs means that a high mechanical efficiency is delivered compared to that of lead screw designs. A typical ball screw may be 90 percent efficient, versus 30 percent efficiency of a lead screw of equal size. Ball screw specification is often a result of an applications requirement to have smooth...
