Line Boring

Line Boring

Line boring is a critical precision machining operation used to restore concentricity and alignment across multiple bearing or shaft housings in marine, power generation, and industrial systems. At YAF Engineering, we offer advanced on-site and workshop-based line boring services using versatile machines and laser alignment tools to ensure maximum accuracy.

Common applications of our line boring services include:

• Crankshaft and camshaft bearing pockets on diesel engine blocks
• Stern tube housings and shaft support brackets
• Corroded liner landing surfaces on engine blocks, with installation of sleeves
• Tail shaft bolt hole machining and honing, including custom bolt/nut fabrication
• Bracket housings across marine and land-based heavy machinery systems

Equipment Capabilities:

• Two portable line boring systems with adjustable bar lengths up to 3 meters
• Diameter range adaptability for a wide array of housings
• Laser-based alignment verification to ensure optimal centerline geometry
• Ability to perform both rotary machining and honing operations

Whether restoring the main bearing alignment on a vessel’s engine or reconditioning critical support housings in an industrial plant, YAF Engineering’s line boring teams provide precision-driven solutions that reduce downtime and restore equipment integrity to OEM or class-approved specifications.
