Model A

main features

robust overall construction (frame construction)
low height with high load capacity, dimensions identical to AS + AM series
fixed connection, as the load plate or cover plate can be screwed in place
most stable load acceptance and distribution
Model A-H (with hardened centre plate) is used when the roller skate is not moved under heavy load for a long period of time. This prevents the hardened steel rollers from pressing into the standard non-hardened centre plate and ensures consistently low rolling resistance.
Model A-H-50CrV4 (roll material 50CrV4) is recommended if the risk of short-term overload beyond the specified load capacity of the roller skates cannot be ruled out or is likely.

Models I-IIIv have 4 mounting holes: the middle ones are omitted.
Maximum displacement speed: ≤ 5 m/min.
For uncontrollable load distribution problems (e.g. wind pressure), choose models with a hardened centre plate and higher-quality roller material 50CrV4.
The rolling resistance for models I-IIIv is 7–5% of the total load, depending on the track, and 5–3% for the larger models.
Also available with guide rollers
Modifications to the drilling pattern in the top plate on request
Corrosion protection (galvanising or stainless steel) on request
