Product Characteristics

Self-centering, two piece low-cost locking assemblies, which can be used - due to the slit - also at larger tolerances. The hub slightly positions during mounting towards the screw head. For disassembly only few release screws are required. Through optimised geometry of the flange, the deformation of the flange is significantly lower than with standard products.

Explanations

L = Overall width
L₁ = Overall width (without screws)
L₃ = Clamping length
d = Inner ring diameter
D = Outer diameter
