New Timing Belt Drive Features Sag Resistant, One-Piece Extrusion Design

ASTON, PA — April 12, 2010 — The new model AZ1040 drive is the most recent extension to the
Amacoil-Uhing line of timing belt drives used for smooth linear motion in positioning and indexing
applications. The drive features a one-piece aluminum profile extrusion which serves as the belt
housing. T-slots and receiver grooves for the load carriage guide bars are incorporated into the
profile design. The one-piece construction permits longer, sag-free stroke lengths without
necessitating scaling up to a larger size drive. In cross-section, the profile reveals a dynamic
crisscross structural pattern which further increases sag resistance and overall durability.

Belt pulleys are built-in to the AZ1040 end caps. T-slots are also designed into the end caps
which provide more options for mounting and integration with other assembly components. The load
carriage measures 188 mm x 160 mm (7.4″ x 6.3″) and has pre-drilled and tapped payload mounting
holes, and also T-slots running parallel to the line of travel. Maximum travel speed is up to 5.0
meters/second (16.4 ft/sec) depending on the weight of the payload which will also affect required
drive torque and acceleration capability. The drive has a repeatability of +/- 0.2 mm (0.008″) over
travel spans of up to 2,000 mm (6.5 ft).

Amacoil-Uhing AZ1040 timing belts are made of a heavy-duty synthetic rubber with a built-in
steel cord strengthener. Multiple profile sections may be joined to accommodate long travel
requirements. Five different AZ models are offered all of which are distributed in the USA by
Amacoil, Inc. who also handles parts, repairs and technical support for Uhing linear drive
