◆The extra super duralumin machined + hard alumite sprocket, which boasts unparalleled strength and precision, covers many models and numbers of teeth for domestic and imported cars, on and off-road. We also have a wide range of conversion products. The sprocket is a fascinating product that transcends the boundaries of an industrial product, embodying ISA's desire to create the world's best products by fully utilizing the design, processing, and finishing technologies of ISA, which specializes in high-precision machining. This is a truly treasured product.・A sprocket machined from ultra-super duralumin that has undergone constant improvements in design and manufacturing methods.・In order to combine the three performances of "accuracy, strength, and wear resistance," we use processing technology, materials, and processing methods that are optimal for each, and are probably the highest standards that can be mass-produced.・A high-quality, high-performance product that overturns common sense regarding sprockets, common mechanical parts. We use NC machine tools for machining, which affects accuracy, and eliminate errors by making the process continuous. We have selected extra super duralumin and 50μm thick hard alumite that meet our own strict standards.・Super duralumin is lightweight, has excellent strength, and has high shape stability for high-precision machining. - In cooperation with the material manufacturer, we used a plate material with a thickness not found in the regular lineup, reducing the amount of cutting and reducing the possibility of distortion. This eliminates wasted processing time and materials, achieving both high quality and reasonable prices. - By eliminating deviations as much as possible and making the process continuous, we have succeeded in dramatically increasing not only the precision of individual machined parts, but also the dimensional precision between them. - The tolerances of the center hole and bolt holes are made as small as possible to minimize eccentricity during installation. The results of this pursuit can be seen in the snug fit when worn.・The surface is coated with 50 micron thick hard alumite to increase wear resistance and enhance the beauty of the machining.・For off-road vehicles, vertical grooves are added to the bottom of the teeth to prevent foreign objects from getting caught and eject them. -The sense of high quality when you touch it will be further confirmed by the high precision that can be seen during installation and the high wear resistance that can be seen through continued use.
