S Type Steel Agricultural Chains

S Type Steel Agricultural Chains are used for power transmission and conveying in agricultural machinery where chain dimensions, sprocket engagement and resistance to field conditions are important. Available in multiple S-series sizes, with material, heat treatment and surface options selected according to the equipment and operating conditions.

Material Selection: Side plates are stamped from high-carbon alloy steel; pins and bushings utilize cold-drawn steel profiles selected for high shear resistance.

Controlled Heat Treatment: Pins and bushings undergo automated induction hardening to maintain a tough, shock-absorbing inner core while achieving wear-resistant surface hardness levels.

Pitch Calibration: Automated stretching and calibration benches pre-load each assembled chain strand to minimize initial running-in elongation in the field.

Protection Treatment: Submerged in heavy-duty industrial anti-corrosion oil to withstand prolonged oceanic transport and open-air warehouse storage prior to installation.

 

 

Attachment Configurations: F2, K2, specialized welded lugs, and custom flight attachments welded to exact center distances.

Pin Modifications: Extended pins, cottered pin designs, or hardened rivet ends for specific retention needs.

Sample Development: Send us your worn sample chain or CAD drawing; our engineering department evaluates tolerances and provides a prototype manufacturing schedule within 48 hours.

 

 

Rapid Apparent "Elongation"
Cause: Installing a new, precise chain onto a worn sprocket with hooked teeth, causing the chain to ride high and wear prematurely.

Recommendation: Inspect sprockets alongside S55 or S62 replacements; replacing worn sprockets simultaneously can extend service life by up to 40%.

Component Fractures in Rocky Soil
Cause: Uniform, over-hardened metal making the chain brittle and susceptible to cracking under impact.

Recommendation: Use controlled dual-stage hardened components that balance surface wear resistance with a shock-absorbing inner core.
