Schaumburg, IL – (February 9, 2006) Well-established as the leading linear motion innovator, THK has once again captured industry attention with the introduction of the world’s smallest linear motion guide. Featuring a rail width of 1mm, the Type RSR1M is the only LM Guide of its size available anywhere in the world.
The Type RSR1M and the Type RSR2M (2 – 4mm rail width) were developed by THK engineers in response to today’s increasing demand for decreased design sizes. The Ultra-Compact RSR Series features minimal rolling resistance and 4-way equal load ratings. Martensitic stainless steel blocks, rails and balls allow for use in harsh environments. Type RSR heights range from 2.5 – 4 mm; block widths are from 4 – 10mm; and block lengths range from 6.2 – 17mm. Basic dynamic and static load ratings are 37 – 307N and 58 – 435N respectively.
THK’s Type RSR is ideal for a variety of applications requiring precise movement, including medical equipment, semiconductor equipment, and measuring instruments.
