DIN 22252 round link chain
Real product reference for mining conveyor chain systems.
Core chain and chainring products for mining, conveying and heavy industrial procurement.
Mining and conveying chain
LeeChain round link chains are designed for conveying equipment and industrial chain applications where dimensional accuracy, stable load performance and reliable service life are critical.
DIN22252:2012
Mining compact chain
Compact chains use forged vertical rings and are applied to different specifications of mining compact chains.
DIN22255:2012
High-strength chain
Reinforced chains are further processed using proprietary heat treatment technology while keeping the same dimensional data as regular chains.
DIN22252:2012 reference verification
Corrosion-resistant chain
Unlike zinc-dipped chains, the corrosion protection of LeeChain anti-corrosion chains does not deteriorate with surface wear.
Low-height chain
Super flat chain has lower height than compact chain and is designed for replacement scenarios where chain height is constrained.
Chain coupling
V-Lock couplings are specially designed for connecting round and compact chains.
