Precision Engineered for Heavy-Duty Performance

Our NK30/30-TV-XL needle roller bearing is a high-performance, drop-in replacement for Cat part number 111-2412, widely used in transmission systems, idler gears, rocker arms, and auxiliary drives of Cat wheel loaders (e.g., 950, 966), dozers (e.g., D6, D8), and other heavy-duty machinery. Built to OEM-equivalent standards, it delivers exceptional load capacity, smooth operation, and long service life—even under extreme shock, vibration, and contamination.

Fully interchangeable with OEM specifications—no machining or modification required. Ensures seamless installation and reliable operation.

Specifically engineered for track idler shafts and tensioner assemblies, where high radial loads, contamination, and constant vibration demand robust performance.

Rollers: Made from vacuum-degassed GCr15 chrome steel, heat-treated to HRC 58–62 for maximum fatigue resistance.Cage: Precision-stamped low-carbon steel with smooth surface finish to reduce friction and wear.

Bore (Shaft Fit): 30 mm

Outer Diameter: 47 mm

Width: 30 mm

Factory-filled with high-viscosity lithium complex grease suitable for wide temperature ranges (–30°C to +150°C). Reduces initial wear and extends relubrication intervals.
