Bearings

Hembrug has a lot of experience machining different kinds of bearings: inner- and outer cylindrical bearings, tapered bearings and ball bearings up to a diameter of 1400 mm. The availability of standard, easily to change and not form specific tools that can machine several operations in one set-up means that the complete machining process chain can significantly be shortened.

Roller Bearings

Hembrug  can also successfully machine tapered rollers, cylindrical rollers and rollers that have logarithmic profile.  The grinding process chain consists of nine process steps, from raw to finished part. Due to the hard turning process characteristics hard turning only requires four process steps substantially reducing the total cycle time with comparable part quality, if not better.
