Cromard®

Laystall manufactures a range of Cromard steel cylinder liners with a minimum wall thickness of 1mm and hard chrome plating in the bore. The hard chrome finish in the bore is micro-channelled using a silicon carbide abrasive process that results in improved lubrication retention and an optimised plateau finish. The plateau finish helps to ensure long piston ring life whilst minimising the retained oil film for reduce emissions and oil consumption. Laystall Cromard steel cylinder liners are supplied pre- finished in the bore, no machining is required once fitted in the engine. Liners can be provided with a ground and graded outside diameter together with a variety of flange sizes including flame lips. In addition to normal service grades of the liner outside diameter, oversize versions may be provided for special engine overhaul requirements. Click to view our Cromard® range
