Application
Delo Tekhnika bearing puller is indispensable during diagnostics, scheduled and operational repairs, and vehicle maintenance. Parts that transmit high torque are heavily pressed. These are not only bearings, but also gears, pulleys, rings, brass couplings and bushings.
The dismantling and installation of the listed parts requires a precisely coordinated and verified effort. In this case, it is important not to destroy the removed element and nearby components: housings, covers, shafts. Fearing such troubles, experienced car mechanics use a professional device in their work - the Delo Techniki bearing puller.
Description of types
Bearings are difficult to undermine, so the devices for their dismantling are made of durable high-alloy steel. Tools with the same principle of action are divided into groups according to the type of grips.
Features of each type
The main types of captures are as follows:
- Sliding. In the fixture, two grippers move freely along the beam. Paw opening - 10-80 mm. Rearranging the stops in places, you can remove the external and internal parts.
- Turning. The grips are fixed at four points with locking bolts. The working width of the paws is up to 7 cm, so the tool is used for small elements.
- Conical. Very precise XNUMX-jaw mechanism with automatic centering that does not allow distortion of parts. The device got its name because of the conical nut, which is wrapped by hand.
- Separator. Reliable simple design, which is based on a separator. Both halves of it are installed under the part to be removed, bolted together, then the upper, pulling part is attached.

General opinion
It is impossible to draw unambiguous conclusions from user reviews. However, an analysis of the statements of members of the forum on various resources shows that there are still more benevolent reviews.
Home craftsmen who complain about the softness of the metal did not take into account the technical characteristics (maximum load) when choosing a fixture. Or the bearings were hopelessly stuck to the body.
