This front idler is a precision-engineered undercarriage component designed specifically for Shantui SD16 crawler bulldozers and compatible models including SD160, SD22, and Komatsu D60/D65 series. As a critical guide wheel mounted at the front of the track frame, it works together with the tension cylinder to maintain proper track tension and alignment, ensuring smooth and stable machine mobility across demanding construction, mining, and earthmoving job sites.

Manufactured from high-strength alloy steel such as ZG40Mn, 35MnB, 40Mn2, or 50Mn through advanced forging and casting techniques, this idler delivers exceptional durability and wear resistance. The wheel rim contact surface undergoes specialised heat treatment to achieve a surface hardness of HRC50-58 with a hardened depth of 8-12mm, providing robust protection against abrasive conditions, heavy impact loads, and stress fatigue. The precision-machined surface ensures accurate engagement with the track chain, while the high-quality bronze bushing and efficient lubricating oil circulation system minimise rotation resistance and extend service life.

Available with part numbers including 16Y-40-03000 (front idler assembly), 175-30-00572, and 175-30-23114, this idler is engineered to meet or exceed OEM specifications. Weighing approximately 198kg, it is built for the most demanding applications, minimising downtime and reducing the frequency of replacements.

As a factory direct supply product from China, this front idler offers a cost-effective alternative without compromising quality or fitment. Available in black or yellow finish with customised options upon request. Backed by ISO9001 certification and a 12-month or 2,000-hour warranty against material and workmanship defects
