Cylinder Hone Stones GEKO for cylinder hones 19–63 mm

Replacement honing stones from GEKO designed for use with cylinder hones and compatible with bore diameters from 19 to 63 mm. These abrasive stones deliver controlled material removal and surface finishing for engine cylinders, hydraulic cylinders and similar round bores. They are intended for rebuilding, smoothing and removing glazing or light wear during routine cylinder maintenance and refurbishment.

Advantages

GEKO cylinder hone stones provide consistent abrasive performance across the specified diameter range, enabling uniform surface texture and efficient material removal. Made to fit standard cylinder hone tools, they simplify replacement and reduce downtime. The stones are suitable for finishing operations that require precision in roundness and cross-hatch pattern restoration without introducing excessive material loss.

Suitable for

• Honing engine cylinder bores
• Refurbishing hydraulic and pneumatic cylinder bores
• Removing glazing, light scoring or surface contamination
• Preparing bores for piston ring seating and sealing

Key specifications

• Compatible bore diameter range: 19–63 mm
• Product type: replacement abrasive honing stones
• Intended use: material removal and surface finishing of round bores
• Compatibility: designed for use with hand and machine cylinder hone tools
• Application areas: engine cylinders, hydraulic cylinders, pneumatic cylinders

How to use

Install the GEKO honing stones according to the cylinder hone tool manufacturer's instructions, ensuring secure mounting and correct orientation. Start with light passes and appropriate cutting speed, progressively increasing pressure only if more material removal is required. Maintain a steady feed and use a controlled cross-hatch motion to achieve an even surface finish. Flush the bore regularly with cutting fluid or solvent to remove abrasive particles and debris, and inspect the surface frequently to avoid over-honing.

Usage recommendations

Use suitable cutting or honing oil to improve stone life and surface finish. Match the stone grit and hone aggressiveness to the material and damage level of the bore: finer grit for finishing and ring seating, coarser grit for removing heavy glazing or light scoring. Always follow safety guidelines, wear eye protection and ensure the workpiece is securely clamped during machining.
