The core business supporting the Mars Rover in the harsh environment of Mars is Kaydon RealiSlim thin-section ball bearings, designed and manufactured by SKF at the company's global thin-section bearing engineering center in Muskegon and its recently expanded Sumter manufacturing center in the United States .
During the months of space travel, these highly engineered components help the survival of the rover’s main robotic arm, sample collection turntable, tool turntable, and sample handling components, as well as its intended function on the surface of Mars.
SKF also provided key bearings for the mission’s launch vehicle, which sent the rover and its lander into space.
SKF bearings will play an indispensable role in the important process of Mars sample collection. When the rover is ready to start collecting samples on the surface, the robotic arm will be manipulated in place, the tool bit turntable will start to run, deploy tools to drill or grind materials, and then the sample collection turntable (aka) collects the "hand") and transfers To the sample processing component for processing on the rover, and eventually may return to Earth for analysis through a future Mars mission.
"The bearings we design and manufacture to help the rover perform its core scientific activities are based on several Kaydon thin-section ball bearing models customized by our engineers to minimize weight and save space, while retaining maximum functionality and maintenance for maintenance tasks. Reliability or replacement is not an option at all," said Isidoro Mazzitelli, director of product development and engineering for the Americas. Space applications must be a fraction of the weight of a standard bearing assembly.
Kaydon bearing solutions are usually customized according to specific customer benchmark models, and are usually used in applications that require a careful balance between strength, weight, size, function and reliability-including robotic surgical equipment, automated precision manufacturing, detailed painting, Aircraft systems, airport security scanners and medical CT imagers.
In addition to the latest missions, SKF has decades of history as a supplier to the global space program, and its history can be traced back to NASA's Apollo 11 mission. "For more than 40 years, our company's bearings, seals and other products have helped achieve a wide range of spacecraft and missions," said John Schmidt, president of SKF America. Commercial and government satellites, space telescopes, various rocket launch vehicles, and space suits for astronauts. When conditions become critical and application requirements are demanding, engineering knowledge is the only way to succeed. "
SKF's mission is to become the undisputed leader in the bearing industry. They do this by providing solutions that reduce friction and carbon dioxide emissions, while increasing machine uptime and performance. Their products and services around rotating shafts include bearings, seals, lubrication management, artificial intelligence and wireless condition monitoring. SKF has representative offices in more than 130 countries and approximately 17,000 dealership outlets worldwide. www.skf.com
