Heavy-Duty Construction
This tooth lock pin roll pin style 5kop / x156/p156 is manufactured using high-alloy steel; tensile ≥1,350 MPa for crack resistance under impact loads. Through-hardened to 20mm depth. Shot-blasted and painted surface for wear inspection at each service. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies

Maintenance Recommendations
– Replace all teeth in a set simultaneously — individual replacement creates load imbalance
– Check adapter pin and retainer condition at each tooth replacement
– Replace any bent or cracked teeth immediately; deformed teeth put side loads on the adapter nose
