Unit satisfies light load, slow move
applications
Mechanically simple but highly innovative, a very attractively priced profile drive unit satisfies the light-load, slow moving application to the more dynamically arduous high speed requirement.
Hepco's new Profile Driven Unit (PDU) plugs a significant gap in linear motion technology It is a robust, high performance system designed specifically for applications requiring a cost effective solution to fit into a compact space envelope

HepcoMotion has developed a new ball screw driven version of its proven Profile Driven Unit.
The PSD120 has good all-round performance in a highly cost efficient, maintenance-free package.
Mechanically simple but highly innovative, PDU is very attractively priced and can satisfy the light-load, slow moving application to the more dynamically arduous high speed requirement.
PDU is the product of a marriage between proven belt technology, advanced engineering materials and Hepco's expertise in aluminium profile design.
It comprises a slotted profile into which fits a drive belt and carriage.

Gradient grinder grooves marble easily
Until the introduction of the Gradient GrinderT, kitchen furniture manufacturers and stonemasons had little option but to create drainage holes in marble and granite worktops by hand.
This arrangement effectively seals the unit.
But perhaps the most significant element of the PDU system is Hepco's new Herculane wheel technology.
These wheels run virtually friction-free on the inside surface of the profile providing stable support for the carriage plate.
The unit offers extremely low friction and due to the wheel rolling motion will run without the need for any lubrication.
Hepco guide wheel systems have long been associated with high-speed operation unmatched by ball-based systems.
PDU is no exception to this rule.
It is rated for operating at speeds up to 6m/s.
At 600N, the PDU's load capacity is equally remarkable for a unit that measures just 60mm x 51mm in cross section.
The carriage plate of the PDU is designed to accommodate the mounting of a second PDU unit.
In this way a compact, high-performance X-Y system can be quickly and easily created.
Integral end of stroke protection is provided as standard.
A choice of motors is provided with PDU, offering driving forces of up to 280N.
A typical AC inverter motor will deliver a linear force of 145N and speeds of over 5m/s.
Optional tubular flanges ensure easy connection to most makes of motors and gearboxes.
Drive shafts can be configured left, right or double and other available options include holding brakes, positioning encoders and limit switches.
Another time-sa/ving feature of the PDU is the built-in switch cam on the carriage plate that can be rotated to change sides.
Naturally, PDU is fully compatible with Hepco's MCS aluminium profile system and its competitors making it an ideal replacement for failing ball-based systems.
Typical applications for the new PDU would be the movement of print heads and similar automation needs in food and pharmaceutical packaging. Request a free brochure from HepcoMotion ...
