Mounting Large Size Bearings

Training aim
This training course communicates more in-depth information on the mounting and dismounting of rolling bearings. Our training centre at the FAG plant in Schweinfurt has various training islands on which large size rolling bearing arrangements typical of industry can be mounted and dismounted. The key points of the content are:

• correct and reliable preparation and implementation of mounting and dismounting
• correct measurement of shafts, bearings and housings
• correct selection of mounting and dismounting methods
• correct use of measuring, mounting and dismounting tools

It is for you to decide at which islands your training should take place and which bearings (of those named below) are to be used during the training. A combination of several training islands or combination with basic training on rolling bearing technology is also possible.

Duration
according to the agreement – 1 day per training platform
(for platform 2 also 2 days possible)
