QAnnealing Range
P.04-011 Spline Shafts are already hardened, and must be annealed before machining. Annealing may lower hardness on the machined P.04-011
Cross Roller Guides area +15mm fore and aft. (See the examples below). Furthermore, the annealing portions are out of the guaranteed range of O.D. Guides Cross Roller
Tolerance. When calculating stroke, count out the dimensions of annealing portions.
