Fast, precise and secure mounting of bearings

Mounting tools are necessary to mount bearings, bushings, sealing rings and pulleys safely, precisely, damage-free and quickly. Especially when mechanically mounting bearings, it is crucial that the bearing is supported on the inside and outside to avoid damage that leads to premature bearing damage.

When using the FIT33 mounting kit, the mounting forces are not transmitted via the balls or rollers in the bearing, so there is no risk of damage to the running surface. The impact-resistant plastic rings have been made from one plate, which prevents breakage, unlike some injection-moulded designs. They prevent metal-to-metal contact and thus avoid damage to the axle.
The FIT33 tool case is suitable for mounting bearings with shaft diameters from 10 to 50 mm and outside diameters from 26 to 110 mm.

Your advantages
