Detailed
About S55 Agricultural Chain
S55 belongs to the DIN 8189 S-type steel agricultural chains. S-type agricultural chains: solid rollers, pre-stretched assembly, heat-treated parts, and dimensions that interchange with other brands' S-type agricultural chains. These chains run on standard S-type sprockets and are built for feeding, conveying, and elevating duties where dust, shock loads, moisture, and long shifts are normal. Inside the S series, S55 stands out for its larger roller, which gives a bigger contact face, so the chain wears more slowly in abrasive or heavy pulling work.

S55 vs Other S-Type Agricultural Chain Sizes
S55 shares its pitch and inner width with the S45 roller chain, so the two look almost identical on the machine. The difference is the roller: S55 uses the larger roller, which is what you pay for when the duty is abrasive or heavily loaded. S52 runs a similar roller on a shorter pitch, while S62 and S77 step up to heavier plates and pins. Check pitch, inner width, and roller together before ordering, and see the full S-type steel agricultural chain sizes.
| Chain Size | Pitch | Inner Width | Min. Tensile Strength |
| S55 | 41.40 mm | 22.23 mm | 18.00 kN |
| S45 | 41.40 mm | 22.23 mm | 18.00 kN |
| S52 | 38.10 mm | 22.23 mm | 18.00 kN |
S62 | 41.91 mm | 26.20 mm | 26.70 kN |
S77 | 58.34 mm | 22.23 mm | 45.00 kN |
Material and Heat Treatment For S55 Roller Chain
Chain plates are punched from 45Mn (SAE 1541 equivalent grade) high-carbon steel and heat-treated; pins and bushings are case-hardened to resist wear. Rollers are solid and shot peened, and plating or black-oxide finishes are available, together with factory lubrication chosen for the duty. Heat treatment is done in-house, so batch records stay with the part — see our heat treatment process page.
