material grades
▶ Fatigue resistant
Straight plates distribute load across a larger cross-section than standard figure-eight profiles, raising the fatigue limit significantly.
▶ Induction-hardened pins
Precision ground and through-hardened for extended wear life under shock loading and high-cycle continuous conveyor duty.
▶ Factory pre-stretched
Pre-loading ensures correct pitch accuracy from the first metre; eliminates the bedding-in elongation common with new chain installations.
▶ Full-strength connecting links
Cottered or spring-clip connecting links retain 100 % of chain rated load at the joint. Optional spin-riveted for permanent assembly.

Straight side plate vs standard roller chain
✓ C-type advantage
- Higher fatigue limit — larger plate cross-section
- Higher static break load at same pitch
- Flat sides guide cleanly in conveyor tracks
- Runs on identical ANSI/ISO sprockets — no tooling change
- Longer service intervals in continuous duty
△ Trade-offs vs standard
- 5–12 % heavier per metre
- Slightly higher unit cost
- Marginally less flexible on very tight-radius turns
Typical applications
▶ Bottling & canning lines
▶ Packaging machinery
▶ Seafood & poultry processing
▶ Petroleum refineries
▶ Car wash conveyors
▶ Citrus processing
▶ Agricultural drives
▶ Material handling & sortation
