Our Undercarriage Parts
Parts By Brands
Track guides are essential components in bulldozer undercarriage systems, responsible for maintaining precise track alignment and preventing derailment, especially during turns or operation on uneven terrain. By keeping the track chain correctly positioned, they help reduce wear, improve overall undercarriage performance, and ensure machine stability under tough working conditions.
PT'ZM manufactures a wide range of high-strength guides and related parts including guide covers and plate retainers, compatible with various Komatsu and Caterpillar dozer models. Made from wear-resistant materials and precision-machined for accuracy, our track guides are built to endure the harsh demands of heavy-duty construction, mining, and earthmoving environments. Whether for routine maintenance or full component replacement, these guides offer reliable fit, extended durability, and consistent performance in the field.
