Construction and Assembly Instructions

The length l₇ is determined by the penetration depth of the plunger pin into the cone of the bushing.

The length l₈ must ensure that the plunger pin fully disengages. Bushing length and plate thickness plus any gap can then be selected within certain margins.

When engaged, the pin hast to have a minimum remaining stroke of 0.5 mm to make sure that the conical section of the pin is located in the cone of the guide bushing without clearance.
For each plunger pin diameter d₁, two different pin lengths l₁ are available.

For a safe remaining stroke: l₉ = l₁ - 0.5 mm
For mounting the bushings with tolerance n6, a hole with tolerance H7, corresponding to the external diameter, is usually provided.
