Komatsu Part BEARING 06002-30213

Product Overview

The 06002-30213 BEARING is a KES (Komatsu Engineering Standard) precision rolling-element bearing from the 06002 series, manufactured to support rotating shafts in Komatsu construction and mining equipment. KES bearings are standardized components that appear across multiple machine models — they're designed to the same material and dimensional specifications regardless of which Komatsu model they're installed in.

Core Function

Rotating shafts throughout your machine depend on bearings for two things — free rotation and accurate positioning. This bearing handles both by absorbing radial and axial loads, reducing friction between moving parts, and maintaining correct shaft alignment within tight tolerances. When a bearing wears, the shaft starts to drift from its intended center, which accelerates wear on seals, gears, and adjacent components.

You'll find this bearing in transmission shafts, final drive planetary carriers, hydraulic pump drives, swing reduction gearboxes, travel motor assemblies, and engine accessory drives.

Replacement Indicators

Replace the 06002-30213 when you observe any of these signs:

• Noise — grinding, rumbling, or rhythmic clicking from the drivetrain
• Vibration — increasingly noticeable, especially when the machine is under load
• Heat — bearing housing temperature above normal for the application
• Contamination — oil or grease that's darkened, thinned, or contains metallic particles
• Clearance — shaft movement that measures beyond Komatsu's allowable service limits

Installation

1. Confirm the part number in your Komatsu catalog
2. Inspect the bearing — rotate by hand and check for smooth motion
3. Clean the mounting surfaces — old lubricant and debris cause misalignment
4. Heat for shaft fitting — an induction heater at 90°C provides controlled expansion
5. Replace all seals — oil seals, O-rings, and gaskets
6. Lubricate per Komatsu's specification
7. Test at low speed — listen for abnormal noise and check housing temperature
