Reduced Downtime
We work with the crankshaft in place, reducing disassembly and getting the equipment back into service faster.
Crankshaft Machining
On-site crankshaft machining to correct crankpins, main journals, ovality, taper and scoring. Specialized service for industrial engines and large equipment.

Why Choose On-Site Crankshaft Machining?
We machine crankshafts for industrial and marine engines, heavy equipment and large machinery, restoring component dimensions, alignment and operating condition.
Crankshaft Preservation
We remove only the material needed to correct the damage, staying within the crankshaft's dimensional limits.
Dimensional Control
We control diameter, ovality, taper and surface finish to ensure correct seating of the bearing shells.
Operational Savings
On-site work reduces the costs and risks of removing, handling and transporting large crankshafts.
Technical Capabilities
We use high-precision equipment to ensure an accurate and efficient machining process.
Crankpin Machining
Correction of connecting rod crankpins affected by scoring, wear, ovality and damage caused by bearing shell failures.
- Ovality correction
- Taper elimination
- Scoring removal
- Controlled diameter
- Finish suited to bearing shells
Main Journal Grinding
Grinding of main bearing journals to restore roundness, alignment and proper lubrication conditions.
- Main bearing journals
- Controlled roundness
- Wear correction
- Restored geometry
- Uniform bearing shell contact
Journal Polishing
Polishing of crankpins and main journals to remove surface marks and achieve the finish specified for the bearing shells.
- Removal of light marks
- Surface roughness control
- Reduced friction
- Uniform surface
- Longer bearing shell life
Thrust Faces
Correction of thrust faces affected by wear and scoring that cause excessive axial play (end float) in the assembly.
- Axial play control
- Face parallelism
- Scoring removal
- Uniform seating
- Greater axial stability
