Regina UP821K Heavy Duty Roller Chain Assembly

Regina UP821K Heavy Duty Roller Chain Assembly is a high-load conveyor chain from Regina’s UP (Ultra-Performance) line, molded in Ultra-Performance Acetal Resin (UP) for durable performance in demanding plastic-chain conveyors. Regina catalogs identify UP821K as part of the 821 UP‑K family and show width variants available in 190.5 mm (7.5 in), 254.0 mm (10 in), and 304.8 mm (12 in) to fit different layouts. A typical working load rating is 2750 N at 25°C (77°F), with chain weight increasing with width (roughly 3.2–5.4 kg/m depending on the specific variant). The product is commonly supplied in a 10-foot length, aligning with retailer listings for UP821K 10 ft chains, and sits within Regina’s broader roller-chain portfolio for conveyor and packaging applications.
