Chain & Drives supply premium quality Senqcia (Hitachi) NEO-SBR Prime Series heavy duty Drill Rig pull-down chain, in various sizes suitable for the drilling industry.
In an application that is highly abrasive and pushes the chain maximum allowable load and fatigue strengths to its limits, Senqcia (Hitachi) standard range of chain and HE Heavy Duty series chains maximises chain service life. Standard throughout the range is theSenqcia (Hitachi) SBR solid bush construction.
By manufacturing the bush from solid bar precision machined to tight tolerances Senqcia (Hitachi) NEO-SBR chain offers 100% contact at the load bearing side plated onto the bushing. Standard chain construction incorporated by many brands still uses flat plate rolled into a bushing.
The rolled or barrel-shaped bush starts elongating as soon as load is applied and is more susceptible to wear and elongation under heavy loading. Senqcia (Hitachi) also incorporates a special double shot peening process for the pin and bush to increase fatigue strength which is critical in heavy load applications such and the Drill Rig pull back chains.
The HE series chain offers greater tensile strengths and maximum allowable loads by incorporating thither heavy duty side plates and thru hardened 4 way riveted pins. Senqcia's (Hitachi) range of NEO-SBR series roller chains used in the mining industry is exclusively imported by Chain and Drives.
Our drill rig chain incorporates all features of NEO-SBR Prime +30% maximum allowable load and triple zone hardening on all components. Our drill rig chain is also available with Senqcia (Hitachi) CR Corrosion Resistant chain coating system.
