221004SH Drum Roller 250DXH90XHL-40
Engineered for transit concrete mixer drums and mobile batching trucks, our 221004SH Drum Roller (250D × H90 × HL-40) provides maximum radial load-bearing stability, smooth rotation, and exceptional resistance to heavy vibrational shocks during full-capacity transit.
Manufactured through precision forging using high-tensile 40Cr / 42CrMo alloy steel, the roller tread is induction-hardened to HRC 55-60 to resist tracking groove wear, flaking, and structural deformation. Complete with precision-sealed, heavy-duty roller bearings and multi-lip labyrinth seals, it ensures complete dust and concrete slurry lockout—delivering seamless drum track alignment and drastically extended service intervals on severe construction sites.
