Size X100 – 160

INFORMATION

Included in the scope of delivery:

2× retaining rings [8][9] and end plate [4].

Not included in the scope of delivery:

Threaded rod [2], nut [5], retaining screw [6], ejector screw [8].

Before mounting the gear unit, degrease the hollow shaft [7] and the machine shaft [1]. Use a commercially available solvent. Do not let the solvent come into contact with the sealing lips of the oil seals.
NOTICE! Never apply assembly paste directly to the bushing [11] because the compound may get into the clamping area of the shrink disk when connecting the input shaft. Possible damage to property. It is essential that the clamping area of the shrink disk between the machine shaft [1] and the hollow shaft [7] remains free of grease.
Apply some assembly paste, such as NOCO-Paste to the machine shaft [1] in the area of the bushing [11].

Attach the inner retaining ring [8] to the hollow shaft [7]. Secure the end plate [4] with the outer retaining ring [9]. Thread the threaded rod [2] into the machine shaft [1].

Observe the following thread sizes of the threaded rods [2].

Size	Strength class 8.8
X..H100 – 150	M24
X..H160	M30

Observe the following information on the retaining rings [8][9].

Size	2 × retaining ring (bore) DIN 472
X..H100	80 × 2.5
X..H110	90 × 2.5
X..H120	100 × 3
X..H130	110 × 4

X..H150	130 × 4
X..H160	140 × 4

INFORMATION

Mounting is easier if you first apply assembly paste to the threaded rod and the nut.

Screw the nut [5] onto the threaded rod up to the end plate [4]. Tighten the nut [5] until the shaft shoulders of the machine shaft [1] and the hollow shaft meet.

Loosen the nut [5]. Remove the threaded rod [2].

Secure the machine shaft [1] with the retaining screw [6]. The retaining screw [6] must also be locked with a suitable threadlocker. Observe the following information on the retaining screw [6].

Slide the shrink disk [9] with untightened screws onto the hollow shaft [7] and position the inner ring of the shrink disk [9b] at dimension A.
CAUTION! The shrink disk can slip when not tightened. Potential risk of crushing due to falling parts. Secure the shrink disk against slipping.
NOTICE! Tightening the locking screws without installed shaft may lead to deformation of the hollow shaft. Possible damage to property. Never tighten the locking screws without the shaft installed.

Tighten the locking screws [10] hand-tight. In doing so, align the outer ring (stepped tapered ring) [9a] parallel to the inner ring (stepped tapered bushing) [9b] of the shrink disk. Tighten the locking screws [10] one after the other in a clockwise direction (not in diametrically opposite sequence), each by a quarter turn. Do not tighten the locking screws [10] in a diametrically opposite sequence.

INFORMATION

For shrink disks with a slotted inner ring (stepped tapered bushing) [9b], tighten the locking screws [10] to the left and right of the slot one after another, and then, in several stages, tighten the remaining screws at evenly spaced intervals.

Work around the ring in several stages, evenly tightening the locking screws [10] by a quarter turn until the outer ring (stepped tapered ring) [9a] and the inner ring (stepped tapered bushing) [9b] align on the face that holds the screws.

If the outer ring (stepped tapered ring) and the inner ring (stepped tapered bushing) cannot be installed in alignment on the screw-side face, check the following tolerances for dimension S. These must not be exceeded while adhering to the maximum tightening torques (e.g. using a torque wrench) of the clamping screws [10].

Dimension S:

Outer diameter of the shrink disk	Dimension S
≤Ø 100	+0.1
≤Ø 300	+0.2
above	+0.25

Maximum tightening torques of the clamping screws [10]:

Clamping screws [10]	Maximum tightening torque in Nm
M10	62
M12	108
M14	171
M16	262
M18	367
M20	513
M22	696
M24	882
M27	1287
M30	1755

If the tolerance values are not adhered to, remove the shrink disk again and clean/lubricate it carefully according to the following chapter.

Mount the protection cover dust-tight to the gear unit.
