Welcome to Linqing Xinshengdi Bearing Co., Ltd.
Tunnel boring machines (TBMs) literally move mountains from the inside out, requiring components that cannot fail underground. The 30232 bearing, with a substantial 160mm inner ring, stabilizes the heavy articulation joints and gear drives behind the main cutting head. It is engineered to neutralize severe asymmetric soil pressure and sudden rock collisions, keeping the massive cutting shield properly aligned and preventing catastrophic sub-surface mechanical blockages.
