Wheel blocks feature:
• Positive travel wheel/shaft connection resulting from the splined shaft section.
Simple, fast assembly and replacement with commercially available tools.
High wheel loads, long service life due to dust-proof anti-friction bearings lubricated
for life.
Simple adjustment of span by re-arranging spacer elements between the wheel
block and the inside of the carriage girder.
Considerably reduced wear on travel wheels (wear indicator) and track rails as a
result of the self-lubricating effect of spheroidal graphite cast iron compared with
steel.
Silent running due to self-damping properties of the travel wheel material.
Travel wheel profile
1) other treads on request
2) max. wheel loads for linear contact (flat rail to DIN 1014 or A rail to DIN 536) depending on FEM group, useful rail width and
long travel speed, see catalogue 203 352 44, section 2.6.5
By re-arranging the spacer elements, the span can be adjusted.
