TACK track rollers use advanced induction hardening treatment to obtain a precisely controlled hardened layer depth, ensuring a high-hardness, high-wear-resistant contact surface and greatly extending service life. From material selection to hardening process to seal design, every link is dedicated to ensuring that TACK track rollers can maintain optimal performance and long service life in extreme weather conditions (severe cold, hot, and humid) and harsh working conditions with high strength, high impact, and high wear.
