PARTS DESCRIPTION
Product Overview
The camshaft rotates inside dedicated bearing surfaces while repeatedly operating the engine valve train. Correct bearing clearance helps support smooth movement and lubrication around the camshaft journals. This 6D155 Camshaft Bearing is intended for compatible Komatsu diesel engine rebuilding and repair.
Because some engines use different bearing sizes at different camshaft positions, buyers should confirm the references and required quantity before ordering.

Why This Part Matters
The camshaft is subjected to repeated loads from valve operation. Its bearings provide support and a controlled running surface, while engine oil creates a protective film between moving surfaces. Correct bearing fitment helps protect the camshaft journals and maintain stable rotation within the valve-train system.
Before assembly, confirm bearing sequence, oil passage alignment, and the condition of the camshaft journals. These checks are part of a careful engine rebuild.
Key Features
- Replacement bearing solution for compatible camshaft support locations
- Designed for correct fitment around the corresponding camshaft journal
- Supports lubrication and friction control in the valve-train system
- Suitable for individual bearing replacement or complete engine rebuilding
- bearing references can be cross-checked before ordering
- Different bearing positions can be reviewed when the engine uses multiple sizes
Fitment & Ordering Note
Before purchase, check whether the engine uses identical bearings at every camshaft position or a mixed-size set. Comparing the references and dimensions is recommended.
