Industrial chains for conveyors and machinery

Complies with Polish and DIN standards
Spomasz Zamość S.A. is a chain manufacturer with several decades of experience.
Our production offer includes a wide assortment of chains made in accordance with Polish Norms and DIN standards. We make chains in a heat-treated version, with protective coatings - zinc or nickel, as well as in acid-resistant version.
Chains are made in versions:
- Inch subdivisions from 1″ to 4½″,
- Drives with metric subdivisions from 30 mm to 250 mm,
- Metric and imperial metric and imperial pitch conveyors in the following types: roller, sleeve, pin and with catches.
Our specialisation is the manufacture of conveyor chains in footed designs. We have very extensive experience in the design and manufacture of chains working in extreme temperature conditions - chains in ice cream freezers, frozen food freezers, chains for fruit and vegetable freezers and chains working in extremely high temperatures - chains for quenching ovens.
A very high level of design experience and modern machinery enable us to manufacture most of the ladder chains you will find - Galla.

position | 1 | 2 | 3 | 4 | 5 | 6 |
---|---|---|---|---|---|---|
symbol | 50 | C | R | 30 | I | K |
- The numbers before the letter designation indicate the chain pitch in millimetres. If the first letter after the digits is "C", this means that the chain pitch value is determined in inches after rounding down and written in millimetres - here 50.8mm
- The item specifies whether the chain pitch is expressed in inches - letter 'C' or in millimetres - no letter.
- The position determines the type of chain
R - roller chain
chain
S - pin chain
T - sleeve - The position indicates the diameter of the reel. For chains with inch pitch (letter C in the second position), the value is rounded "down" and expressed in [mm]. For chains with metric pitch, the value specifies the exact diameter of the roller.
- The position determines additional parameters of the chain
D - bent legs (or welded or riveted)
Da - legs bent on one side
E - chain with welded plate - carrier
Do - legs bent on both sides
Dw - legs bent in direction of chain axis
F - chain with protruding pin
G - chain with additional plate
H - additional legs not bent
I - chain with hollow pin
W - multi-plate chain - The item indicates the type of chain material or coating covering the chain. If there is no letter, the chain is made of heat-treated carbon steel.
P - electroplated or hot-dip galvanised chain - galvanised
K - chain made of acid resistant steel
