描述
We supply genuine Sandvik support rings (Part# 638050652), critical structural components engineered specifically for MB670 bolter miner chassis and boom articulation systems. Manufactured from quenched and tempered 34CrNiMo6 alloy steel, this ring provides exceptional compressive strength (1,200 MPa yield) while maintaining impact toughness in underground mining conditions.
Precision-machined to ±0.02mm tolerances, the support ring ensures perfect load distribution across mating surfaces, preventing stress concentration in boom pivot points subjected to 25-ton dynamic loads. Each component undergoes ultrasonic testing for internal defects and magnetic particle inspection for surface cracks, guaranteeing structural integrity in demanding bolting applications. The zinc-nickel plating provides 1,000-hour salt spray resistance for corrosive mine environments.
Our global inventory supports 24-hour emergency delivery to mining operations worldwide. Each order includes installation torque specifications and alignment procedures validated by Sandvik engineering standards.
