Hardened steel bushed (HSB) chains are designed as a substitute for combination chains where conditions require a heavier, more rugged chain.

Sidebars are medium carbon heat treated steel. Pins are alloy heat treated steel. Pins of 3⁄4″ diameter and larger are also induction hardened. Bushings are furnished in case hardened steel to provide maximum wear resistance and chain life.

Riveted construction is recommended for wood yards and sawmills. Cottered construction is recommended for elevators and conveyors. Chain pins will be alternating, except on HSB131 and HSB188.

HSB chains are interchangeable with other standard makes of corresponding sizes and numbers. They are also a direct upgrade to combination chains of the same number.

HSB chains are used for bucket elevators, wood yard conveyors and other types of conveyors and elevators operating under gritty and abrasive conditions. These chains have proven themselves in operation for long life and low maintenance.

Maximum chain speed depends upon size of sprockets. For Conveyor Service see Table 2, Section A.
