Raw Material

We pay special emphasis on raw materials to begin with. As compared to competition we have focused on the smallest part as well. Focus areas when choosing raw materials:

  • Light weight and structural material
  • Resistant to corrosion
  • Endures high temperatures

Raw Material Cylinder High grade ADC12 with copper content of 1.65% Substandard ADC12 with copper content of 0.5-0.8% which is below international standards High Copper content in Cylinder & Pistons substantial increases in strength and facilitates precipitation hardening
Piston High grade AC8A with copper content of 1.65% Substandard ADC12 with copper content of 0.5-0.8% which is below international standards We use raw material composition engineered to reduce ductility and corrosion resistance. More ductility i.e. ? 1% leads to vesatility and higher performance at lower cost
Sleeve High Grade Cast Iron Low Grade Cast Iron Heat treated Corrosion resistant iron grade for robust function and less wear & tear
Rings High Grade Rings Material – Compression Ring – DH 30 Nodular cast iron 2. Wiper Ring – (DQ20) STEEL 3. Oil Ring – DS45) STEEL Normal Steel rings 1. We offer Lightweight & structural material 2. With precise specifications from high grade grey iron castings. Derived from OEM factory – ATG
Piston Pin High Grade (20CrMo) Steel Low grade Steel Our product has high Resistant to corrosion
Gasket Fresh Rubber (NBR) Recycled Rubber Seal proof operation without any power loss

Manufacturing

Each step in the manufacturing process is as per global standards, below comparison explains how we manufacture our products.

Parameter Details At RITSUKA Chinese Product RITSUKA Advantage
Manufacturing Product Technology Fully Automated CNC machines with a capacity of 1 Cylinder per minuts Semi Automated CNC or Lathe machines By using fully automated CNC machines, RITSUKA offers min Tolerance level product with negligible
Vertical Milling Centre Fully Automatic VMC (Vertical milling centre) VMC not available with most of the factories RITSUKA Piston manufactured using VMC for preciesed Piston pin Bore and oil slots. These machine only available with OEM manufacturers
Head Treatment 350 degree Heat treatment Max 250 degree Heat treatment 1. We Ensure increase in hardness and obtain maximum strength and durability 2. maintain Brinnel Hardness range of ≥74.1 HBS
Paint Shop Automatic Paint Shop Semi Automatic/Manual painting facility 1. Makes product visually appealing for longer duration without paint peeloff 2. We offer intenational standard finish which affect the ability of the part to resist wear and fatgue. Rust free surface throuth out life cycle
Electroplating 0.6-0.8 Microns Not Consistent

Apart from giving the spare part the perfect appearance, a good finishing helps to create a smoother surface for higher overall functioning of a motorcycle. We offer both Color painted (Shiny black, Silver, Matt) & Sand blasted finish on Cylinder.

Testing

We offer products that meet international quality standards. We offer a high grade ADC12 with copper content of 1.60-1.70%. Whereas, the other Chinese products’ copper content is even less than international standard of 1.2% and above.Copper increases the resistance of a material to breaking under tension or load.

In process Checking at Every Process thru various process specific testing Gauges. Random Dimensional check with Three axis coordinate measuring machine Visual testing Control the Standard Parameters at every Process Maintains sleeve diameter tolerance level of 0.002 mm ~ 0.003 mm
Final Inspection Pneumatic gauge for checking piston fitment and movement in cylinder sleeve Manual gauge for checking piston movement in cylinder sleeve Standard Fitment Check
Functional Test (Cylinder mounted on Engine tested for 380 hours) Motorcycle with our Cylinder is tested in running condition continuously for 380 hrs. and variation found in sleeve inner dia is only -0.012mm. Standard Fitment Check Only OEM level factories have this facility As per International standard test to be conducted for 200 hrs. and variation should not be more than 0.02mm. Hence our product is ahead of OEM standards
