Bearing insertion apparatus

In thermolacquered aluminium. Carefully made. To be used for holding plates from 50 to 220 mm, and with pillars of 70 mm height maximum. Allows several operations, such as centering, reaming, milling and practical for all plates from tableclock to grandfather- clock. By using appropriate stakes and punches, this tool removes and sets brass or bronze bushings even for very large clocks as: ”Comtoise”or Morbier clocks etc. Dimensions: 355 x 355 x 180 mm. Contents: 1 tool with 2 arms and 2 chucks 1 broach with hand wheel In wooden box: 3 driving punches 1 centring bit 1 undrilled stake 4 drilled stakes 2 centring stakes 10 reamers 2 chamfering tools 5 pivot cutters 1 Jacob’s chuck

This machine facilitates the replacement of brass and bronze bearings in clocks. Clock boards with a size of 50 - 220 mm are clamped in the machine. The reamer is placed in a brooch and lowered by means of a hand crank on the board; You now rub a hole in the board in direct power transmission. This eliminates the tedious rubbing of the bearings with the hand reamers. The reamers are designed so that they are precisely matched to the Ø of the bearings and thus the bearings can be hammered directly onto this machine (by hammering the brooch) without remeasuring. Included: 1 centering anvil with tip 9 mm 4 422 614 4 anvils drilled Ø 8 - 30 mm 4 422 609 to 4 422 612 10 reamers Ø 1,20 - 8,47 mm 4 422 615 to 4 422 624 1 burr cutter Ø 4 mm 4 422 630 3 press-in punches Ø 3 - 6 - 9 mm 4 422 604 1 anvil undrilled Ø 25 mm 4 422 608 1 center point 4 422 607.

Ideal tool for replacing defective bearings in watch movements and precision mechanical devices. Worn bores are reamed effortlessly and precisely and then hard brass bushings are pressed in. Robust cast aluminum frame, finely ground steel spindle with hand wheel, 2 extension arms with adjustable clamping claws. Suitable for plates from 50-220 mm and movements with a pillar height of up to 70 mm. Frame height 20 cm, weight 2.4 kg.
