5.7 Check steel strip deflectors and steel strip sliding rods
Steel strip deflections and steel strip sliding rods must be exchanged if:

the recommended exchange interval of the wear parts is reached (see Table 11).

abnormal or one-sided wear is present on the wear parts, due to improper
operation conditions or environmental influences, extensive soiling from outside
or incorrect installation of the steel belt cover.
Figure 17: Abnormal wear of steel strip deflecion (left) and steel strip sliding rods (right)
Abnormal wear is present if

At the steel strip deflection the lateral residual web thickness falls below the value
T01 or the wear at the sliding surface exceeds the value T02.

At the steel strip sliding rod the thickness of the sliding rod falls below the value

Exchange procedure of steel strip deflections and steel strip sliding rods
To exchange the carriage lid, it is not necessary to to completely remove the steel
strip cover (see page 43).
5.8 Exchange guiding system
Exchanging the guiding system is only possible at the assembly plant and not at
customer's site.
If damaged (due to impacts, soiling, loads or environmental conditions), the
complete linear axis must be exchanged. Furthermore, it should be exchanged as
soon as the forecasted lifetime of the linear actuator is reached.
