Puller 100mm three-arm with jaw locking, Czech production

Robust high-quality three-arm puller, suitable for disassembly of bearings, pulleys and other rotating circular machine parts

Length of arms from pins to packs: 100mm
Screw: M14

The puller consists of 3 swinging arms, for which it is possible to change the length 70/78 mm by a simple adjustment. The width of the arms is 8mm. Changing the arm length also changes the maximum opening value.

With an arm length of 70mm, the maximum opening between the curved ends of the arms is 100mm, so the diameter of the bearing or pulley can be up to 124mm, but it depends on the height at the clamping point. The maximum possible height of the clamped part is 50 mm.
When adjusting the arms to a length of 78 mm, the maximum opening between the curved ends of the arms is 140 mm, the diameter of the bearing or pulley can be up to 124 mm, but it depends on the height at the clamping point. The maximum height of the clamped part is 60 mm.

Jaw height (paw): 6mm / 11mm (gap required to lower the bearing)
Depth of jaws: 12mm (from shoulder to tooth)
Total jaw width: 25mm

Tightening and locking the arms in the clamped position is done with a knurled nut on the main screw. By screwing the nut down, the arms are locked in the retracted position.
At the place where the thrust screw rests on the tightened part, there is a reinforced steel ball dia. 7.5mm. The size of the thrust bolt is M14x1.5. The cross clamping lever has a diameter of 8 mm and a length of 180 mm.

Rigid construction withstands high stress.
Especially suitable for lowering bearings, pulleys, gears, etc.
When pulling, the jaws are firmly pressed under the part to be scanned.
