This paper aims to calculate the running resistance...

... magnetic fluid. Taking the common roller in mining equipment as an example, sealing performance tests were conducted using a mining roller running resistance test bench in the simulated underground environment. Findings In routine environmental tests, the running resistance of the new magnetic liquid...
