For Maruzen
SR-2
You'll find more accurate projectile line.
This set has a Precision Cylinder,Taper Cylinder Head,Spring Guide & Vacuum Piston.
The vacuum system reduces a negative pressure.
※If use this piston to extreme power spring as PDI SS,SPR & over 2J setting,it's possible to be shorter life.
Because those sprigns gives extreme power over Toy. It's up to your operation & maintenance.
Included these parts.
Precision Cylinder / Taper Cylinder Head / Spring Guide / Vacuum Piston
Palsonite Cylinder : Toughnes & beauty Cylinder
We adapt new technology of 01 & 05 inner barrels called "cold hammering".This cylinder is same accuracy as Inner barrel. The inner diameter tolerance is 1/100mm In spite of cylinder.
We have never seen as this accuracy tolerance of this cylinder.
Using this cylinder,the piston will get more speed & you'll get stable output.
We processed the Palsonite to precision cylinder to be less friction between a piston & cylinder.
So you'll get more smooth action & that gives stable & high power performance.
4 parallel pins
We use 4 parallel pins(Dia.3mm) to combine the boss end with cylinder body.No other makers is stronger than ours.Almost maker use a split pin which is weaker than parallel pin.
The welded points
Combine body & End Boss.
※The tolerance described by our company refers to the "straight" part which is not machined.
The slotted part is not related to the airtight performance so its tolerance is not design to be as tight as other places.
