Adjustable thrust for linear actuators
Linear actuators convert rotary motion to linear travel and carry loads at speeds up to 180cm/s, depending on size, for positioning operations in all types of machinery.
Overhung load adapters provide motor support
Zero-Max OHLA overhung load adapters provide load support to prevent bearing wear to motors and pumps.
More flexibility for couplings
Zero-Max reckons its CD couplings are more versatile than ever using the new QD hub and bushing model.
Designed to handle thrust rated between 22 and 890N, loads can be easily attached to the Roh'lix carrier block using two cap screws.
The Roh'lix thrust capacity is adjustable so that the system will disengage if the preset thrust is exceeded, providing overload protection if an obstruction is encountered in the system.
Roh'lix linear actuators consist of three precision ball bearings (which are replaceable) at each end of a two-piece aluminium carrier block.
Mounted at an angle to the drive axis, the six bearings convert drive shaft rotation into proportional linear travel.
With a minimum of 90% efficiency, the Roh'lix can normally provide up to 2500km of linear travel.
The moveable Roh'lix carrier block travels on a smooth, threadless hardened RC 58 shaft that requires no lubrication.
Besides being easy to install, the Roh'lix is compact and requires little maintenance, an important feature in today's automation systems.
Applications include pick and place, packaging machines, sprayers, back gauges, door openers, transfer table and positioners for stretch wrap packaging systems, screen printers and many other machines.
Five standard Roh'lix sizes are available for 0.375 to 2in diameter shafts, or metric shaft sizes from 8 to 50mm diameter.
Also available are Quick Disconnect Roh'lix models that disengage the Roh'lix block from the shaft, allowing switchover of equipment from automatic to manual operation and back again.
Sizes are from 0.375 to 0.75in and 8 to 20mm shaft diameters.
(Shafts are not included in either Roh'lix models). Request a free brochure from Zero-Max ...
