1. Straight-Line Efficiency & Stability
The 821 chain plate is optimized for straight running applications, maintaining consistent tension and tracking without lateral movement. The flat, wide surface provides stable support for bottles, cartons, and cases, preventing tipping or skewing at transfer points. Its low-friction material reduces drive power consumption and wear on wear strips, extending system life.
2. Modular & Easy to Maintain
Individual modules are linked by stainless steel or plastic hinge rods, allowing damaged sections to be replaced in minutes without removing the entire belt. This modular design reduces downtime and spare parts costs. The belt can be cut to any width using standard tools, and edge modules are available to create custom widths for specific product dimensions.
3. Lubrication-Free & Hygienic
The acetal or polypropylene material runs dry, eliminating oil or grease contamination risks – critical for food, beverage, and pharmaceutical lines. The open hinge design allows liquid drainage and debris fall-through, preventing product buildup. The belt withstands frequent washdowns with hot water or mild detergents and is compatible with FDA and EU food contact standards.
Product Uses
1. Beverage Can & Bottle Conveying
The 821 chain plate is widely used in filling, rinsing, labeling, and packing lines for PET bottles, glass bottles, and aluminum cans. Its flat surface maintains container stability at high speeds (up to 60 m/min). The open hinge drains spilled liquids away from the belt surface, reducing slip and bacterial growth. Single-file or mass flow configurations are both supported.
2. Case & Carton Transport in Warehousing
In distribution centers and packaging halls, the 821 chain plate moves corrugated cases, display trays, and shrink-wrapped bundles between palletizers, stretch wrappers, and truck loaders. The wide belt accommodates mixed case sizes without requiring change parts. Its low-noise operation benefits office-adjacent facilities, while the modular design allows quick reconfiguration for seasonal product changes.
3. General Manufacturing Assembly Lines
The 821 chain plate transports plastic parts, metal stampings, electronic subassemblies, and automotive components through manual workstations or automated assembly cells. Its anti-static or conductive grades protect sensitive electronics. The belt can be fitted with cleats, sidewalls, or guide rails for incline conveying or product separation. Easy cleaning supports lean manufacturing practices.

















The 821 straight running chain plate is a modular plastic conveyor belt designed for straight-line material transport. It features an 821 series pitch of 25.4 mm (1 inch) and is available in nominal widths ranging from 82 mm to over 300 mm. The belt surface is available in flat and textured configurations.
Each module is manufactured through injection molding using acetal (POM) or polypropylene (PP) resin. Individual modules are connected by hinge rods to form a continuous belt of specified width and length. The belt engages with matching-pitch sprockets for positive drive without slippage. The open-hinge design allows airflow and liquid drainage through the belt surface.

The 821 series chain plate is engineered for straight-running conveyor applications. The interlocking module geometry maintains consistent belt tracking without lateral movement during operation. The flat contact surface provides stable support for containers, cartons, and packaged goods at transfer points.
Damaged belt sections can be replaced by removing the affected modules and hinge rods, without disassembling the entire belt length. This modular construction reduces downtime for repairs and lowers spare part inventory requirements. Belt width can be adjusted by adding or removing edge modules using standard hand tools.
The acetal and polypropylene materials operate without lubrication, eliminating oil or grease contamination risks. The open hinge structure allows liquid drainage and debris fall-through, reducing residue buildup on the belt surface. Both material grades withstand regular washdowns with hot water and mild detergent solutions.
The 821 series has a pitch of 25.4 mm, which equals 1 inch. This pitch dimension must match the sprocket pitch for proper drive engagement.
Yes, both acetal (POM) and polypropylene (PP) versions are available in food-contact compatible grades that meet FDA and EU food contact standards. Material grade specifications should be confirmed during ordering.
Individual modules are replaced by removing the hinge rod that connects the damaged section, swapping the affected modules, and reinserting the hinge rod. The entire belt does not need to be removed from the conveyor for this repair.
Compatible sprockets include 19-tooth and 21-tooth configurations for both drive and passive positions. Specific dimensions vary by model, with bore diameters ranging from 38 mm to 75 mm depending on the application requirements.
