HIGH PRECISION RACKS and PINIONS

All our racks are interchangeable When it comes to rack quality, choosing Reckon® ensures that the following aspects are seriously taken care of: - Toothing precision is inspected on a CMM with last generation rack-inspection software and our racks are delivered to you with detailed inspection reports showing: o Flatness o Straightness o individual and cumulative pith errors o the precision of the faces towards teeth and bottom - Material quality, as Reckon® only selects stabilized material from the best suppliers, so you do not suffer from any low of precision due to residual stress...

Teeth milled to DIN 10h27, pressure angle 20° Mounting side and bottom milled (Ra=3.2) Material: C45 Heat treatment: induction-hardening on teeth only (50-55 HRC) Decorative black coating (thickness under 3^m) Each model hereabove can be ordered without holes by simply replacing “H1” by “H0” at the end of the reference. All dimensions are mm. Other sizes and modules available upon request. 2D/3D Drawings available upon request (1) : M = Module / (2) : Z = Number of teeth / (3) : H = Number of holes / (4) : CPE = Cumulative Pitch Error on 300mm
