Production program

All our products reflect the precision and the passion for the profession.

Bierens designs, produces, revises and reconstructs. From gearboxes and pumps to drive shafts, sprockets, timing belt pulleys and spline-connections. The following production program shows the editing group and the maximum dimensions of the operation or of the production machine.

Gears:
Note: it refers here to the dimensions that we simply can produce. Depending on the shape, dimensions and weight of the gears we can also manufacture larger diameters in a number of cases. For diameters larger than Ø 2500 we kindly request you to contact us in order to discuss the possibilities, because at Bierens everything is possible!
