OEM Manufacturing and Part Matching
This product is manufactured as an OEM replacement part. It is not described as a genuine Komatsu component. The Komatsu name and machine model are used only to identify the intended equipment application.
OEM production can be checked according to:
- Part number 21T-09-31120
- Complete Komatsu PC2000 machine model
- Equipment serial number
- Technical drawing
- Original bearing sample
- Critical mounting and connection dimensions
If the original part has been replaced or modified previously, we recommend sending the old bearing or a complete dimensional drawing before production.
Important Quality and Dimensional Checks
The bearing must match the corresponding equipment assembly accurately. Important inspection points include:
- Inner and outer diameter
- Bearing width
- Load specification
- Internal clearance
- Seal or shield configuration
- Matching shaft and housing dimensions
Final material, production process, heat treatment and surface finish will be confirmed according to the sample, drawing and order requirements where applicable.
Why Correct Fitment Matters
Using an incorrectly matched bearing may result in:
- Incorrect shaft or housing fit
- Abnormal noise and vibration
- Excessive friction or heat
- Shaft misalignment
- Damage to rotating components
Part number verification should therefore be combined with machine information and dimensional confirmation.
