Flatness In Running Direction
In 1938 Rexnord introduced the worlds first metal TableTop chain with integrated top plate and hinge eyes. Nowadays the
Rexnord and MCC product lines of steel slatband chains offer many materials, types and grades, enabling a solution for any
application. Metal slatband chains are ideal for handling glass bottles, PET containers, kegs, crates and many other products.
Features
Surface finish
When products are sliding on a chain, the bottom will aff
ect 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, Rexnord uses a number of chain
materials, specifically designed for slatband chain applications. You can find more
details on these materials on next page.
Flatness
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 metal 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.
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 Rexnord 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.
Hardened Pins
Hardened pin material reduces the chain elongation significantly. Special hardened
pins will give the highest resistance to chain elongation over a long period of time.
High quality 60-Series HB metal TableTop
chain with Hardened Pins with improved
wear resistance properties. Special 66-Series XHB metal TableTop
with special
hardened pins to offer superior wear resistance properties.
