FEATURES
- Surface finish
When products are sliding on a chain, the bottom will affect the
surface finish of the chain. Rexnord tests have shown that during
the first days after installation the initial surface finish is changing to
a lower level that is maintained during the normal life of the chain.
Surface finish is a valuable feature, although it is not the determining
factor between good and great performance.
- Sliding properties
These depend on the base material and the treatments during the
manufacturing process. To ensure superior sliding properties, Rexnor
uses a number of patented chain materials, specifically designed for slatband chain applications. You can
find more details on these materials on next page.
During the entire production process the flatness is measured in running
direction (R) and in width direction (W)
The flatness in width direction is important when products slide
sideways from one chain to the other. For this reason the cross
sections of all Rexnord and MCC chains are convex instead of concave,
to prevent products to fall. Due to the careful control in production, these chains offer superior lateral flatness
values, which can be found in the tables on the page of each chain.
Flatness when a product moves from one link of the chain to the next
is also important, as poor flatness will cause products
tipping, leading to production loss in the line. MCC and Rexnord steel slatband chains
offer an outstanding flatness in running direction
Working load
At which load a chain is actually breaking is not relevant to
determine if a certain chain is suitable for your application. More important is
the maximum working load a chain can handle before permanent deformation occurs.
Rexnords chain calculation program will assist in defining the right chain for specified
applications, considering conveyor length, chain speed, accumulation level,
lubrication, product type and weight.
- Ground finish
Certain customers prefer steel slatband with ground finish for its
sliding properties. The specification table on the product page of each chain
indicates whether a chain surface finish is ground or non-ground.
- Polished hinge eyes
The performance of the chain on high-speed side-transfers, such as pressure-less combiners improves with polished
hinge eyes, due to the smooth contact with the wearstrips. This prevents pulsating of the chain
and improves product handling. Most Rexnor` sideflexing chains have polished hinge eyes, because these are always in contact with the curve.
The specification table of each chain indicates whether a chain has polished hinge eyes.
