The CAT 214-6800 is a Caterpillar original single-flange track roller, designed for use on the chassis of small tracked construction machinery. It supports the weight of the machine and rolls along the track tracks. The following data is the original specifications and does not include information on replacement parts.
Core Technical Parameters (Raw Data)
Item Details
Basic Attributes
Model 214-6800, Type: Single-flange track track roller (integrated double-row needle roller bearing with sealed lubrication chamber), suitable for mini excavators, skid steer loaders, and other tracked chassis, single weight 18.5 kg, operating temperature -40℃ to +120℃, adopts lifetime grease-sealed design, maintenance-free cycle ≥5000 hours, used for load-bearing and guiding of tracked walking systems, reducing track friction and improving walking stability
Key Dimensions (Metric/Imperial)
Tread diameter 180 mm (7.087 in), Flange diameter 220 mm (8.661 in), Mounting width 200 mm (7.874 in), Shaft diameter 50 mm (1.969 in), Shaft length 250 mm (9.843 in), Inner spacing 114 mm (4.488 in), Outer spacing 260 mm (10.236 in), Mounting bolt specifications M16×1.5, bolt hole spacing 120 mm, chamfered ends 2×45°, compatible track pitch 120 mm
Performance Parameters: Tread material 42CrMo alloy steel, surface hardened HRC 58-62, needle roller hardness HRC 62-65, sealing rating IP67, radial load capacity ≥50 kN, suitable travel speed ≤8 km/h, wear life ≥8000 hours, resistant to mud, water, and dust corrosion under engineering machinery conditions, and can withstand high-frequency impact loads.
Structure and Compatibility Characteristics:
Integrated sealing and lubrication structure: Built-in double-row needle roller bearings, using a double-lip skeleton oil seal + dust ring combination seal, filled with extreme pressure lithium-based grease to prevent mud, water, and dust intrusion, achieving lifetime lubrication and maintenance-free operation, suitable for long-term use under harsh working conditions.
Single flange guiding design: The single flange structure effectively prevents track chain misalignment, adapting to the narrow track gauge design of small tracked equipment, improving guiding accuracy during travel and turning, and avoiding the risk of track derailment.
High-strength load-bearing capacity: The tread undergoes surface hardening treatment, providing high wear resistance and impact resistance. It can support the weight of the entire machine and withstand ground impacts during movement, making it compatible with the tracked systems of mini excavators, skid steer loaders, and other equipment.
Installation and Maintenance Points (Original Data)
Installation: Clean the track roller axle and mounting bracket (free of oil and metal shavings). Tighten the bolts to a torque of 180-200 N·m, ensuring the track roller end face is in close contact with the bracket, with a coaxiality ≤0.05 mm and a spacing deviation between adjacent track rollers ≤2 mm.
Maintenance: Check the sealing condition and tread wear every 2000 hours. Replace immediately if tread wear ≥5 mm or if the seal is leaking oil. For long-term storage, apply rust-preventive oil to the track roller surface and store in a dry environment to prevent Cat® corrosion…
