Original Press Release:

Now Available New Hepcomotion® PDU2M Belt Driven Unit for Moment Loads from Bishop-Wisecarver

New addition to popular PDU2 line offers increased moment load capacity and stiffness suitable for multi-axis systems and demanding single-axis applications

Pittsburg, CA -- Bishop-Wisecarver Corporation, manufacturer of the original DualVee® guide wheel and industry leader in guided motion technology, announces the availability of the new HepcoMotion® PDU2M Profile Belt Driven Unit, a high capacity version of the successful PDU2. The PDU2M incorporates a carriage that contains four extra rollers on each side in order to withstand increased moment forces. Suitable for demanding single-axis systems and multi-axis applications, the PDU2M delivers a 50% higher load capacity, a 200% increase in moment load capacity and a 1,000% improvement in moment load stiffness compared to the standard PDU2. Designers can now specify a single PDU2M unit as a horizontal axis in an X-Z system, where previously two PDU2 units working in parallel would have been required to provide the necessary rigidity and strength.

PDU2M is comprised of a rigid but lightweight aluminum slotted profile fitted with a toothed belt drive and carriage which effectively encloses the unit. Rated for operating speeds up to 6m/s and loads up to 750N, PDU2M's 20AT3 belt allows for driving forces up to 280N. Left, right or double drive shafts can be specified together with a range of options such as brakes, positioning encoders and mechanical or inductive limit switches. Internal bumpers provide end of stroke protection at both ends.

Key to this unit is the extra ultra-high performance HepcoMotion Herculane® wheels that are mounted on adjustable eccentric studs. These wheels run virtually friction-free on the inside of the profile providing stable support for the carriage plate; felt wipers sweep debris from their path. Several carriage styles are available to allow for quick and easy construction of multi-axis systems with minimal brackets and hardware.

PDU2 is fully compatible with aluminum profile systems (which Bishop-Wisecarver carries) and is an ideal replacement for failing ball-based systems that are unable to match its speed and reliability.
