The star back Afam Steel Sprocket 525 the Steel asterisk of AFAM 525 is executed on the exact equipment with computer management. Teeths are processed according to the last standards for the maximum service life of a chain and more effective transfer of power. Teeth and outer diameter are cut off at the same time. It guarantees that koncentrichna teeths in relation to the center of an asterisk. Technological features: Each asterisk is exposed to heat treatment by means of induction training, and then to a holiday for obtaining precisely necessary hardness for durability and effective transfer of power. To correct any deformation which could arise at these stages asterisks pass via the special machine for editing. The star is made of C45 brand steel (constructional carbonaceous qualitative) with a special corrosion-resistant coating, has the increased durability and durability. Are executed in silvery (galvanized) or black (electrophoresis) color for long protection against corrosion. The normalized steel prevents formation of microcracks in asterisk material. It guarantees quality of a product to offer you safe driving. Surpass standard factory stars in operational and strength characteristics of a star of Afam. Thanks to special manufacturing techniques have the lowest weight among motorcycle stars without decrease in rigidity. Important: It is recommended to change at the same time both stars and a chain. Not the really worn-out star left, apparently, will reduce service life of all set. Installation (use) of stars with other quantity of teeths leads to change of the maximum speed and dynamics of dispersal. Characteristics: Internal diameter 134 Diameter of an opening 10.5 Intercenter distances 160 Quantity of openings 6 Quantity of teeth 39 Proizvodstvo Japan
