Cylinder Liner Bedford Sleeve 4.108 31358117 SU 553201 79.375mm

Specifications

 We manufacture cylinder liners and blocks from centrifugally casted, shell casted with closely grained cast irons. Our cylinder liners are heat treated. Further, our cylinder bores are cross honed and diameters are properly ground finish to achieve the highest level of accuracy.

We manufacture our liners, using graded cast iron & centrifugal casting etc. These are available at hardness of the material, 80-85 HRB (20mm-300mm). Further, our range is of industry leading price.

We offer cylinder block, which has grooves formed on the outer surface of the cylinder liner and each of these grooves are extended in a circumferential direction of the cylinder liner in a ring shape. These are used in air coolers, water coolers and automobile industries etc.

Cylinder Liners manufactured by the "Centrifugal Cast Process" is acknowledged to be the best method. In the centrifugal casting process, the molten metals is poured into a metal mould or die which is revolving at a high speed. The centrifugal force causes the metal to distribute itself evenly around the die. Crown International also manufactures Centricast Liners, Centrifugal Liners and Chromed Bore Liners for automobile applications.

Our expertise lies in manufacturing high quality Sleeves. Our Sleeves are reckoned for having excellent casting and machining qualities that add to the durability and performance of the engine they are fitted in. Our Sleeves are available in wide range suitable for varied light, medium and heavy duty applications. Further, we make our Sleeves available at very competitive prices.

We have in-house centrifugal casting foundry and machine shop following lean-manufacturing and environment friendly practices to produce Sleeves that are metallurgical perfect, dimensionally accurate and competitive priced. The Sleeves are manufactured using the centrifugal casting process, which gives a uniform micro structure and eliminates blow holes and other casting defects by using the centrifugal force of a die rotating at a high speed to force out casting defects and impurities.
