S-Type Steel Agricultural Chain | Professional Selection Guide

Correct selection of S-type steel agricultural chains is essential to ensure stable operation and long service life of farm machinery under harsh working conditions. These specially structured agricultural chains feature excellent wear resistance, impact toughness and anti-corrosion performance, ideal for dusty, muddy and high-frequency farm operation scenarios.
Chain selection mainly depends on equipment type, load weight and working speed. For light-duty grain conveying, seedling machines and small harvesting equipment, standard small-pitch models such as S32, S42 and S45 are the optimal choices, offering flexible transmission and low operational consumption. For medium-load machinery including combine harvesters and crop balers, S52, S55 and S62 with higher tensile strength are widely adopted to withstand continuous material impact and friction.
For heavy-duty farm equipment working in severe environments, heavy reinforced seriesHS45, HS55, HS62 are strongly recommended.
They adopt thickened chain plates and optimized heat treatment to resist overload operation and reduce fatigue damage.
Meanwhile, models with F-type attachments can be selected according to installation demands, perfectly matching crop conveying and material lifting structures.
All our S-type agricultural chains follow standard pitch specifications. Scientific model selection effectively avoids chain elongation, jamming and breakage, lowering maintenance costs and improving overall working efficiency of agricultural machinery.
