curves are available in five different materials. The standard material, Combi-A,
is a high grade of polyethylene. It is suitable for most lubricated applications with steel and
plastic chains. In clean environment and with low chain speeds Combi-A can also be used in
dry running applications. For dry running applications with plastic TableTop chains Combi-L
and Combi-S are recommended. These materials are able to work with higher chain speeds.
Combi-S has the largest application field, where Combi-L offers better noise reduction.
Rexnords calculation program determines the PV (pressure-velocity) load on the curve in a
specific application and will advise in which application load and speed require Combi-L or
Combi-S curves. For lubricated, abrasive applications (filler discharge) or abrasive, dry run-
ning applications (glassworks) with (stainless) steel chains, Combi-G is most suitable. This
ceramic reinforced polyethylene offers an extremely good wear resistance. New Generation
Combi-X curves can be applied in high speed (dry running) applications.

Combi-X New Generation Hybrid Construction
A combination of standard resin base material combined with high performance ULF (Ultra
Low Friction) guiding strips makes optimum use of different materials. Guiding strips are
permanently fixed to the basepart.
Non Marking Tubular Returnpart
With todays high speed conveyor applications and sometimes also abrasive conditions, it is
required that the chain surface remains in optimum condition to avoid any unwanted product
handling issues. Therfore Rexnord has developed a special Non Marking return section to be
combined with the standard Magnetflex
upper part. This new returnpart features a Stainless
Steel tubular return which reduces abrasive wear of the chain topsurface. The result is that
the chain surface will remain in perfect condition over a long period of time, and optimum
product handling at high speeds can be achieved.
Tab and Bevel
In many industry segments Tab and Bevel curves and straight tracks are an economic solu-
tion if stability of the product conveyed, cleanability and ease of installation are not the key
areas of interest. They are available for TableTop
, Multiflex and Plate Top chains. Tab and
Bevel machined profiles retain the chains in a mechanical way. For these tracks a high grade,
wear resistant polyethylene is used.
High PV-limit
The Magnetflex
Combi-X has improved PV-properties with respect to the original Rexnord
Nylatron curve material. This means the curves can be applied in high speed (dry running)
applications.
Customized curves
If these standard versions do not meet specific conveyor needs, it is possible to order cus-
tomized versions. Both standard and customer specific curves can be supplied in just several
working days.
