Machining

To avoid damage when pushing on bushes,
housing etc. shafts are chamfered at the
ends as shown in exaple 1.

Centric thread bore on the face side. With thread bores which reach almost to the outer layer, the tolerance of the external diameter may deviate slightly. In case of type D center holes DIN 332 unless otherwise specified, only the
thread is produed without center holes.

Shaft PIN in a turned or ground finisch.

Shaft end with thread. Depending on the diameter of the shaft and thread, the ends can be annealed. Threading is soft. Thread run-out with or without thread groove.

Shaft end with transverse bore and shaft end with transverse through bore. The shaft is annealed in the area of the borehole. If annealing is not permissible, the bore will be countersunk on both sides.

Shaft end with groove for retaining ring. In the case of hardened shafts, the shaft end is annealed and soft or configured as required. Hardened shafts will be annealed or soft following DIN 471, or configured as required.

Shaft end with counter sinking for stud bolts.

Shafts with radial bores

The specifications for annealing apply to precision steel shafts and inductively hardened piston rods.

* Up to M 16, threads are formed using a non-metal cutting process, so ensuring high strength and greater accuracy.

Compound shafts

Recommendation: d2 minimum measurement = d1 + 0,5 mm

* Above diameter 60 mm, fitting plugs d2 with tolerance g 7 are provided.

Compound shafts with a total length of more than 8 m are delivered unassembled. A smooth transition radius is guaranteed only if during assembly it is certain that the markings on the joints correspond exactly.

Shafts may in some cases be delivered ready-assembled. On plugged-in shafts the transverse bores which are closest to the joint should lie together as closely as possible and have a common support.
