Rollmann trading co offers linear motion systems and ball screws from thk. The thk lm system is a unique motion systems in which linear motion is supported by rolling contacts. The contact between the balls and the circular groove raceway is developed from a conventional point contact to a line contact .The line contact means thk guides can handle 13 times work load and last 2200 times longer than conventional linear guide of same ball diameter with higher rigidity. Thk lm systems can compensate for most of the irregularities in the mounting surface and errors in the machine assembly. These are extensively used in semi conductor production equipment, industrial robots, machining centers, grinding machines, printing machines, medical equipments, punch press, measuring instruments, packaging machines etc.
