Solid Roller | Solid Bushing | Shot-Peened Surfaces | Specially Selected Alloy Steel | State of the Art Heat Treatment Process
HKK provides three types of 81X series engineering class conveyor chains: 81X, 81XH Heavy and 81XH-S Heavy Special. Each type is designed with different link plate thickness and height to achieve progressively higher allowable loads and durability. HKK’s 81X series chains are all equipped with cold-forged, shot peened, solid rollers and solid bushings. This, accompanied with specially selected alloy steels and a computer monitored heat treatment process, ensures long life under the harshest conditions.
Solid Roller | Solid Bushing | Custom Spacing | State of the Art Heat Treatment Process
HKK 81X attachments are manufactured using specially selected alloy steel, and a state of the art heat treatment process. Roller link attachments have cold-forged solid bushings and solid rollers. Custom spacing of attachments are readily available.
Solid Bushing | Solid Roller | Side Split Roof Top | No Ridges | Smooth Top
HKK 81X Roof-Top chain has a unique side split feature. This smooth style roof-top will help protect transferring lumber from scratches and dents while reducing build up of unwanted dust in the chain mechanism. Cold-forged solid rollers and solid bushings greatly extend chain life. Specially selected alloy steel and a computer monitored heat treatment process ensure high strength and durability.
Solid Roller | Solid Bushing | Through-Hardened Pins | Less Wood Damage | Faster Processing
HKK Edger chain is well suited for today’s high output lumber industry. Our cold-forged solid rollers, solid bushing and solid center plates, along with through-hardened pins make HKK chain extremely durable even at high RPMs. Shot-peened side plates made from specially selected alloy steel have a proven point tooth design for higher grip with less down force.
Solid Roller | Solid Bushing | Runs on Standard Sprockets | Through-Hardened Pins | Less Wood Damage | Faster Processing
HKK 80-2 Heavy Edger chain is manufactured to handle higher capacity and shock loads than standard chains. Cold-forged solid bushings, solid rollers and thicker outside plates provide longer life with less chain elongation. Shot-peened side plates made from specially selected alloy steel have a proven point tooth design for higher grip with less down force. HKK 80-2 Heavy Edger chain runs on standard 80-2 sprockets to provide easy installation.
