Self-aligning Two Roller 

In addition to the ball on disc arrangement, the TE 54 is also supplied with a self-aligning carrier to allow a 25 mm diameter by 8 mm wide roller to be mounted in place of the ball specimen, thus resulting in an 8 mm wide line contact. Thinner rollers can be manufactured in order to produce narrower line contacts.

The TE 54 Mini Traction Machine brings together proven design elements from the long established TE 55 Two Roller Lubricity Test Machine and a scaled-down version of the common DC link AC vector drive system used on the TE 74 Two Roller Machines. The servo pneumatic loading system is taken straight from the TE 67 Pin on Disc/Reciprocating Pin on Plate Machine.
