BMZR ORING CHAINBMZR ORING CHAIN High quality components coupled with a factory greased seal ring ensure superior rigidity. High tensile steel is used throughout the chain components; larger pins mean loads spread out over the wider area, resulting in longer life and more strength. Specially controlled heat treatment means tougher material and more durability. 11,000 + LB Tensile Strength Specifically Designed for high performance, high load applications Use 120
