CMLA linear actuators offer compact performance and reliability

CMLA linear actuators offer compact performance and reliability

Posted On: 24 April 2015

The new CMLA electromechanical linear actuator range from Columbus McKinnon has been designed to handle the toughest operating conditions. The CMLA linear actuators are compact and can be mounted in any position, which makes them suitable for any number of applications in the food, chemical, process and metalworking industries.

Columbus McKinnon, through its Pfaff-Silberblau and ALLTEC Antriebstechnik brands, brings a combination of technologies to deliver high performance electromechanical components for linear motion technology.

With the CMLA linear actuator, customers get excellent reliability, but now in an even more compact, more powerful unit. The CMLA is available in four load specifications from 500kg to 1300kg with rated outputs of 5,000 to 13,000 N. Its outer tube is made of anodised aluminium, the housing of aluminium and the rod heads of stainless steel. The translation tube is hard-chrome plated.

As the unit is pre-wired, installation is 'plug and play’ simple. Its optional ball screw and low gear ratio make for high lifting speeds. The CMLA is suited for precision applications due to its precise positioning and its repeat accuracy. It also offers constant lifting power through the complete stroke, its standard stroke length being up to 1,000mm.

As the unit boasts case hardened gears and a bronze driving nut, it will offer an exceptionally long life. None of its power transmission components are plastic. Low maintenance is ensured through the use of high-quality lubricants to last for its full operating life.

The CMLA's motors, brakes and drive mechanism are designed in accordance with DIN EN 60034-5, protection class IP 65 for outdoor use in a temperature range of 0˚C to 60˚C.

A special motor gives the CMLA linear actuator maximum power with minimum size compared to motors in similar applications. While a three-phase AC 3Ph 400V (50 Hz) motor is standard, a direct current 24V motor is an option on P50 and P70 models. Efficiency is enhanced thanks to a two-stage straight-toothed spur gear and an optional ball screw. All rotating parts run on high-quality ball bearings.

Mechanical limit switches are standard although variable magnetic limit switches are an option. The CMLA is fitted with a self-locking trapezoidal screw, with a ball screw as an option. An anti-turn device is standard and no external control elements are needed. The unit is also supplied with a wide range of accessories.

As the unit is modular, and an adequate supply of components is kept in stock, operating hours are maximised.

Columbus McKinnon CMLA linear actuators are available in South Africa from Yale Engineering Products (Pty) Ltd, a subsidiary of Columbus McKinnon.
