Piston Rings Manufactured in special Cast Iron, Nodular / Ductile(KV1), IKA as per DIN Standards, Malleable Martensite Iron, Steel Rings as per JIS Standards in the diameter range of 40mm to 130mm dia and Axial width from 0.8mm to 3 mm. SPRL supplies of Piston Rings PVD, Ceramic (CECRO) Coated with Hard Chrome Plating, Nitrated, Mn phosphated & Ferrous coated in rectangular, wedge key stone shaped Napier with plain & barrel honed.
The two critical dimensions required in rings are the Axial thickness (known as the width) and the size of the gap when the ring is closed to its working diameter.
SAMKRG manufacturers both Cast Iron, IKA, Tuff 'B' Alloy, Nodular (Ductile) rings to suit the requirements of the automotive markets. Cast Iron rings are in the diameter range of 35mm to 130mm and steel rings as per DIN/JIS standards in the diameter range of 35mm to 130mm with a axial width from 0.8mm to 3mm for Motorcycles, Cars, LCV's, HCV's, Tractors and Industrial Engines.
