Metrol Ltd. - World's First Vacuum + Pneumatic Shock Absorber (with sensor)

Suitable for use in semiconductor, food and pharmaceutical production processes that do not permit the leakage of oil. Also useful for HACCP and ISO14001

Prevents problems with product defects and environmental contamination
- The use of an internal structure combining vacuum and compression without using oil eliminates any concerns over complaints arising from serious product defects of environmental contamination caused by leakage of oil.
Accommodation of both clean environments and harsh environments
- The IP67 protective construction enables these shock absorbers to be used in both environmens requiring a high degree of cleanliness where conventional oil-based shock absorbers were unable to be used, as well as harsh environtments where coolant is used.
Three jobs with one device, reduced equipment size and less space
- As a result of containing a built-in sensor and stopper within the shock absorber body, three jobs can be performed with a single device, realizing shock absorption, stopper functioning and sensing.
Improved Operating Rates and Reduced Maintenance Costs
- The longer service life (3 milion operations) and MTBF (mean time between failure) as compared with oil-based shock absorbers enable increased equipment operating rates and reduced maintenance costs.
Improved productivity
- Since the air return design (connected to compressed air source) eliminates any recoil during seating, there is no need to press in twice.
- The rapid return speed of the piston rod contributes to shortened tact time.
- The low initial impact during collision eliminates the need for a slowdown step.
