HSP Drive Chains

High Strength & Performance

HSP (High Strength & Performance) Chains are engineered to deliver unmatched strength and durability under extreme operating conditions. By combining a proven chain design with optimized materials and advanced metallurgical specifications, they set a new benchmark in reliability and service life.

With up to 60% higher tensile and fatigue strength compared to standard roller

chains, HSP Chains provide the extra safety margin that demanding industries require. Whether it’s continuous operation, heavy dynamic loads, or harsh environments – HSP Chains ensure consistent performance when it matters most.

Maximum performance for the toughest applications.

What Makes HSP Chains Stronger

Straight side plates for maximum fatigue strength
Ball-drifted inner and outer plates for maximum press-fit and extended service life
High pre-load minimizes initial elongation and maximizes chain life
Shot-peened plates and rollers for extreme endurance
Through-hardened, shot-peened pins with engineered metallurgy for maximum breaking load strength without compromising fatigue strength

Result: up to 40–60% higher tensile strength and significantly improved fatigue resistance.

Made for Heavy-Duty Applications

HSP chains are the first choice in industries where machines operate around the clock under maximum load:

Heavy-duty drives in mechanical and plant engineering
Conveyor technology with high dynamic loads
Construction and agricultural machinery
Paper, packaging, and woodworking industries
Chemical and process engineering
