MA/ML45 series


LOADING IMAGES

Adjustable and unique: these ACE industrial shock absorbers with M45x1.5 threaded body (also available with 1"3/4-12 UNF thread: order code without -M at the end), which can be precisely adjusted at the front and rear, also contribute to the success of the MAGNUM range. Equipped with excellent sealing technology, an annealed guide bearing and an integrated thrust bearing, they are robust and durable.

These shock absorbers absorb 50% more energy than their predecessors while being even more compact. The wider range of effective masses also makes many design and mounting options possible. All these factors make the MA4525, MA4550, MA4575, ML4525, ML4550, and ML4575 series particularly suitable for effective masses from 3000 kg to 180,000 kg. When application data is constantly changing and a high degree of flexibility is required, they are the ideal solution.

These adjustable industrial shock absorbers are used in all areas of mechanical engineering, e.g. in automation, integrated in linear slides or swivel units and also for gantry cranes.

Mounting: your choice
Fixed stop: integrated
Adjustment: Hard impact at the beginning of the stroke, setting of the ring towards 9 or PLUS. Hard impact at the end of the stroke, setting of the ring towards 0 or LESS.
Materials: Outer body: hardened steel; piston rod: hard chrome plated steel; stop: hardened and corrosion resistant coated steel; return spring: zinc plated steel or plastic coated; accessories: phosphated or hardened steel.
Damping fluid : Automatic Transmission Fluid (ATF) for the standard configuration. Models -HT: High temperature synthetic oil. Models -LT : low temperature hydraulic oil.

Note: Noise reduction from 3 dB to 7 dB is possible by using the special bumper (PP). For emergency stop applications and for continuous operation (with additional cooling), it is sometimes possible to exceed the specified maximum capacities. In this case, please consult us.

Safety instructions: External materials from the immediate environment can attack the sealing components and shorten the service life. Please contact us for proposals for suitable solutions. Do not paint the
shock absorbers due to heat emission.

Special oils, nickel plating, increased corrosion protection, integration in pneumatic cylinders or other special options are available on request.
