EZ Align caseSelling Points

  • Fast identification of current types of misalignment, including offset, vertical- and horizontal-angle misalignment.
  • The EZ Align transmitter products a small laser line to a reflector placed on the opposite pulley and instantly gives indications offset and vertical-angle misalignment.
  • It automatically reflected back to the transmitter and indicating horizontal-angle misalignment.
  • Runs with all metallic sheaves and sprockets
  • Magnetically attaching to the inner or outer faces of industrial pulleys to give a quick and accurate drive alignment.
  • Incredibly lightweight and simply to use. A unique person can analyze pulley misalignment in few minutes without formation.
  • Deliver with a durable carrying case, so no small part could be lost.

Gates Laser AT-1

Laser AT-1 on sprocketsNoises, vibrations, and usury on pulleys, belts and bearings … A stop machine could be caused by improper pulley alignment. It can be avoid by using Gates’ new laser alignment device AT-1.

The standard method to measure misalignment is putting a straight edge up to the pulleys. By using the LASER AT-1, there is a second method much faster and more accurate. Installed in few seconds, the laser line projected on the targets indicates you to quickly ascertain and correct misalignment.

Laser AT-1
The LASER AT-1 identifies parallel and angular misalignment between pulleys and it can be used for pulley diameters of 60 mm and larger. It can be installed on non-magnetic pulleys with a double sided adhesive tape and used on both horizontally and vertically mounted machines.

  • For V-belts and timing belts
  • Indicates parallel and angular misalignment between the pulleys
  • Faster and more accurate than measuring with current methods
  • Can be used for horizontally and vertically mounted machines
  • A unique person is needed
  • Can be used in non-magnetic pulleys

The Laser AT-1 is rapidly attached. You can facilely see the laser line projection. When the line lies in the slots of the targets, the machine is in the right position. It provides a fast and precise alignment.
