The CAT 316-5016 is a Caterpillar track roller (single flange/central flange, for tracked construction machinery chassis) that bears the weight of the machine and guides the tracks for smooth operation. It is suitable for small and medium-sized excavators/loaders, with strong adaptability and durability, ensuring low failure rate operation of the chassis system. The following is the core information:
Core Technical Parameters
Item Details
Part Model CAT 316-5016 (3165016) Track Roller, single flange/central flange design, complete assembly including roller housing, shaft, bearing, seals, end caps, etc.
Material Roller Housing: 40Mn2 alloy steel forging, surface hardened HRC52-56 (hardened layer 4-6mm); Shaft: 42CrMo quenched and tempered (HRC38-42); Bearing: Double row tapered roller bearing (52100 bearing steel); Seal: Double lip skeleton oil seal + dust ring, high pressure resistant and anti-aging
Key Dimensions Tread diameter 107mm, roller housing width 120mm, shaft diameter 38mm, mounting hole spacing 150mm, total width 190mm, suitable track pitch 120-130mm, single roller weight approximately 12kg
Compatible Models CAT 305.5E2/306E2/307E2 excavators, 906H loaders, and other small to medium-sized tracked equipment, suitable for track widths of 450-500mm, operating speeds ≤5km/h, heavy-duty conditions.
Performance Parameters: Radial rated load 180kN, limiting speed (oil lubrication) 600rpm, operating temperature -40℃ to 120℃, sealing pressure resistance 0.8MPa, dustproof and waterproof rating IP65, suitable for dusty, muddy, and other harsh working conditions.
Core Functions and Structural Features:
Load Bearing and Guiding: Single flange/central flange restricts lateral track movement to prevent derailment; alloy steel roller housings with hardened surfaces bear the weight and impact of the entire machine, suitable for heavy-duty operations.
Sealing and Contamination Prevention: Double-lip oil seal + dustproof ring combination prevents mud, sand, and water from entering the bearing cavity, ensuring clean grease, extending bearing and roller life, and reducing maintenance frequency.
Stable operation: Double-row tapered roller bearings withstand radial and bidirectional axial loads, ensuring high shaft rotational accuracy, reducing chassis vibration and noise, guaranteeing smooth track movement, and improving work efficiency.
Durable and wear-resistant: The hardened layer of the roller housing is wear-resistant, and the shaft and bearings are fatigue-resistant, adaptable to cyclic loads, with a service life of over 4000 working hours (depending on working conditions).
