description

This bushing is the rear camshaft journal bearing for C10 and C12 engines. It is made of bimetallic wear-resistant alloy with precision machined 29.95 mm bore and oil hole for continuous lubrication. It is pressed into cylinder head housing to restrain camshaft radial runout and bear cyclic load. It protects camshaft journal from wear. It is widely used for overhaul of highway trucks and generator sets. Replace it when bore scoring, excessive clearance or alloy peeling occurs to avoid timing noise and unstable oil pressure.

• Designed to handle high loads and rotational speeds experienced by the camshaft.
• Resistant to wear and damage, ensuring long-lasting performance.
• Minimum Rockwell hardness is 30 newton.

1. OEM inner dimension for correct clearance and camshaft concentricity after press fit.
2. Bimetallic construction provides good fatigue resistance and oil erosion resistance for heavy duty.
3. Accurate oil hole alignment ensures reliable lubrication and prevents seizure.
4. Sold as rear bearing only, economical repair without replacing full camshaft bearing set.
5. Matches original cylinder head bore, direct press fit with no modification.

FAQ 

Q: Is 128-0411 a full set of camshaft bearings?
A: No, it is only the rear journal bearing. Other positions are sold separately.

Q: Can C12 bearing fit C15?
A: No. Bore and outer diameter differ, not interchangeable.

Q: Can bearing with minor scratches be reused?
A: Replace if alloy peeling or excessive clearance occurs, it will seize the camshaft journal.
