Product Details

AirsoftParts NBU Silent Cylinder Head for Bore Up Air Seal Systems

AirsoftParts NBU silent cylinder head is a CNC-machined component for AEG air seal systems made from EN AW 6012 T6 duralumin. The NBU version is designed for Bore Up air seal systems with enlarged dimensions and must be combined with an NBU cylinder and NBU nozzle. The design combines a sealing collar and a large rubber impact pad into a single component that seals the head inside the cylinder while helping to cushion mechanical shocks when the piston head impacts. Together with an additional sealing ring, it creates a double seal. The impact pad has a hardness of 70 ShA. The duralumin body features an electroless nickel-plated finish that creates a uniform and very smooth surface with high wear and corrosion resistance. According to the manufacturer, the surface hardness after plating reaches 660–850 HV (58–63 HRC). The low friction of the nickel-plated surface also promotes smooth movement of the compatible NBU nozzle. The head weighs 11.5 g, is designed for V2 and V3 gearboxes with the corresponding NBU air seal system, and the manufacturer specifies a maximum recommended spring of M170. Made in the Czech Republic.

Key Features

NBU Design for Bore Up Air Seal Systems

The enlarged design corresponds to an NBU / Bore Up air seal system. For proper operation, the cylinder head must be combined with the corresponding NBU cylinder and NBU nozzle.

Sealing Collar and Impact Pad in One Piece

The integrated design combines a sealing collar with a rubber impact pad. A single component therefore seals the head inside the cylinder while also helping to cushion impacts from the piston assembly.

Double Seal

The combination of a sealing collar and an additional sealing ring helps limit air leakage between the cylinder head and NBU cylinder and supports proper sealing of the air seal system.

Large 70 ShA Impact Pad

The large rubber impact pad with a hardness of 70 ShA helps cushion and distribute mechanical shocks generated when the piston head impacts.

Electroless Nickel-Plated Finish

Electroless nickel plating creates a uniform, hard and smooth surface layer with high wear and corrosion resistance. The low-friction surface also promotes smooth movement of the NBU nozzle.

Frequently Asked Questions (FAQ)

Can the NBU Silent Cylinder Head Be Used With a Standard Cylinder and Nozzle?

No. The NBU version is designed for Bore Up air seal systems and must be combined with an NBU cylinder and NBU nozzle. A standard cylinder and standard nozzle are not intended for this version.

What Is the Difference Between the Standard Silent Cylinder Head and the NBU Version?

The NBU version is dimensioned for Bore Up air seal systems and requires the corresponding NBU cylinder and nozzle. For this version, the manufacturer also specifies an impact pad with a hardness of 70 ShA.

How Does the Double Cylinder Head Seal Work?

Sealing is provided by a sealing collar together with an additional sealing ring. The collar is also structurally integrated with the rubber impact pad into a single component.

What Are the Benefits of the Electroless Nickel-Plated Finish?

Electroless nickel plating creates a hard, uniform and smooth surface with high resistance to wear and corrosion. The smooth surface also reduces friction as the NBU nozzle moves over the cylinder head.
