Every time the Perseverance Mars Rover collects or handles rock and regolith samples in Jezero Crater throughout its multiple-year mission on the floor of the crimson planet, key elements from SKF will facilitate that these actions efficiently happen, in keeping with the corporate.
about:blankEnabling the Mars Rover’s core operations within the harsh surroundings on Mars are Kaydon RealiSlim thin-section ball bearings, designed and manufactured by SKF.
The corporate produces the bearings at its international thin-section bearing engineering middle in Muskegon, Michigan, and its lately expanded manufacturing hub in Sumter, South Carolina.
“These extremely engineered elements contribute to the survival of the rover’s major robotic arm, sample-collecting turret, tool-bit carousel and sample-handling meeting throughout a months-long journey via house, and its perform as meant on the Mars floor,” SKF defined in a information launch.
SKF additionally provided important bearings for the mission’s launch automobile that carried the rover and its lander into house.
SKF bearings will play an integral function within the very important technique of pattern assortment on Mars. When the rover is able to start gathering samples on the floor, the robotic arm will maneuver into place and the tool-bit carousel will whirr into motion, deploying instruments to drill or abrade materials, which is able to then be collected by the sample-collecting turret (aka “the hand”) and transferred to the sample-handling meeting for processing onboard the rover, and ultimately a possible return to Earth for evaluation through a future Mars mission.
about:clean“The bearings we designed and constructed to assist the rover carry out its core science actions had been based mostly on a number of fashions of Kaydon thin-section ball bearings custom-made by our engineers to reduce weight and save house, whereas retaining most performance and reliability for a mission the place restore or substitute is solely not an possibility,” stated Isidoro Mazzitelli, director of product growth and engineering Americas. House purposes have to be a small fraction of the burden of normal bearing assemblies.
Kaydon bearing options are sometimes custom-made from baseline fashions for particular prospects and generally utilized in purposes that require a cautious steadiness between energy, weight, measurement, performance and reliability – together with robotic surgical gear, automated precision manufacturing, detailed portray, plane methods, airport safety scanners and medical CT imagers, in keeping with SKF.
Along with the most recent mission, SKF has a decades-long historical past as a provider to international house packages, relationship all the way in which again to NASA’s Apollo 11 mission.
“Our firm’s bearings, seals and different merchandise have helped allow a variety of spacecraft and missions for greater than 40 years,” stated John Schmidt, president of SKF USA Inc. “Our elements have flown on the earlier house missions, dozens of business and authorities satellites, space-borne telescopes, a variety of rocket-launch automobiles and in astronaut’s spacesuits. When situations change into important and purposes demanding, engineering data is the one approach to success.”
