Introduction

Chain and link designations

The chain guide presents currently available FlexLink conveyor chain types, catalogue items as well as special order types. Please consult the FlexLink conveyor catalogue for basic information about our conveyor program, and about conveyor chains.

Two forms of product designations are used. Catalogue products use a designation beginning with X, whereas non-catalogue products are identified by means of a 7-digit specification number.

As a standard the chains come in approximately 5 m lengths (XB and XT Compact: 3 m).

Order cleated chain by specifying cleat type and cleat link frequency as a product designation suffix. A cleat frequency of 8 means that every 8th link is a cleated link.

When cleated chain consists of two combined links, other than standard plain chain links (see XSTP 5/XLTP 5/...), both links are specified, with the cleated link at the top.

Note. To order X85 cleated chain, use the online configurator.

Demo chains

The following demo chains can be ordered. A demo chain contains the most common types of links, one of each type. Standard materials only.

Product family Order No.
Demo chain XS 3905780
Demo chain XL 3905781
Demo chain XM 3905782
Demo chain X85 5111222
Demo chain XH 3905783
Demo chain XK 3925720
 
Example 1

XSTF 5×9 D8 is a 5 m chain section. It has type D cleats, 9 mm high, on every 8th link. The 7 links between the cleated links are type XSTL 44 plain links (see plain chain XSTP 5).
The link kit* for the cleated links is 5056045. Since plain links are used between cleats, the link kit for those is 5056061.

Example 2

Add “PARn” as a suffix to the designation, for chains with drawing numbers. “n” specifies the cleat frequency:

3924158 PAR8 is a 5 m chain section. It has a link type 3902443 on every 8th link. The 7 links between the cleated links are type XLTL 63 plain links.
The link kit* for the cleated links is 5056564. Since plain links are used between cleats, the link kit for those is 5056085.

Example 3

Cleated chain 3924170 PAR.. consists of elevated top links 3904503 combined with cleated links 3904502. This is indicated as follows in the chain guide:

Chain Link(s) Link kit*(s)
3924170 PAR... 3904502
3904503
5056293
5056294

*Link kits

For replacement purposes, the chain links are available in Link kits. Each link kit contains 10 links, 10 plastic pivots, and 10 stainless steel pins, unless otherwise specified.

Note. Individual links cannot be ordered. Link designations are only intended for reference purposes.


Chain pitch and weight

The chain guide also lists the weight of most links. To calculate chain weight, you need to know the chain pitch (see picture below), the weight of the plastic pivot, the weight of the steel pin, and the cleat separation. See the following table.

Technical specifications – base link

Links

The base link parts of the chain links have the same basic shape, and the same technical properties. Five different materials are used. The standard material is acetal resin (POM). Two different types of acetal resin are used:

POM A:  Acetal resin with silicone additive
POM B:  Acetal resin, silicone free

Strength values at 20 °C:

The other materials are not as strong as POM:

  • Polyester (PBT): 50 % of POM value
  • Polyvinylidene fluoride (PVDF) and conductive POM: 40 % of POM value.
  • Intrinsically static dissipative (ISD) POM: see the following table.
