FAQ

Are the load units for TM15WNS the same as the TR series?
No. The TM miniature series states basic load ratings in kN and allowable moments in N·m, while the TR/SR series uses kgf and kg·mm. Convert before comparing (1 kgf ≈ 9.81 N).
How do I choose between the stainless and carbon steel types?
The last letter is S for stainless and A for carbon (alloy) steel. Choose S for semiconductor, food and medical applications where corrosion resistance and cleanliness matter; A is more economical for general automation. Dimensions and load ratings are identical.
How long can TM rails be?
Lengths beyond 1300 mm are made up of two or more rails butted together — confirm the butt-joint accuracy and support method with the maker. Accuracy is N / H / P; clearance is ZF / Z0 / Z1.
