R = 0.3 or below, R1 = 0.5 or below
The surface of the rod should be finished by buffling (SPBF) to 0.8 to 1.6 μmRz (0.2 to 0.4 μmRz).
● The roughness is JIS B 2601 : 2001. When regulation length cannot be kept, apply Pt.

R = 0.3 or below, R1 = 0.5 or below ,R2 = 1
The inner surface of the cylinder tube should be finished by buring (RLB) or honing (GH) to 0.4 to 3.2 μmRz (0.1 to 0.8 μmRa).
specially under severe lubricating condition, burnishing is required.
● The roughness is JIS B 2601 : 2001. When regulation length cannot be kept, apply Pt.
