This worm gear drive unit is a key component in military Fire Control Systems (FCS), enabling precise horizontal movement of gun barrels or sensor modules. It consists of a worm shaft, worm wheel, housing, bearings, and sealing/lubrication systems. The mechanism converts rotational motion into high-torque, slow-speed lateral positioning, ensuring accurate target tracking and stable alignment. Made from high-strength stainless steel and brass alloy, it offers durability, low friction, and smooth meshing. CNC machining minimizes tooth profile errors, while brass housing reduces wear. Self-locking prevents reverse motion from recoil or vibration. Sealed construction blocks dust and moisture, and optimized housing stiffness and bearing preload ensure performance in shock, vibration, and temperature extremes. Quality checks on profile accuracy, backlash, runout, and torque guarantee micron-level precision and repeatable positioning in harsh military environments.

This dipstick is used in the KM9 Armored Combat Dozer to measure lubricant levels in the engine, transmission, or hydraulic system. In military equipment, regular fluid checks are vital for proper operation and preventing failures.

The tip has markings such as “LOW,” “FULL,” and “COLD IDLE,” enabling quick visual confirmation of whether the oil is within range. To measure, insert the dipstick fully into its port, remove it, and compare the oil mark with the reference lines. Readings vary with operating or idle states and temperature.

Built for extreme military conditions—vibration, shock, and temperature changes—the dipstick uses high-strength metal with a corrosion-resistant finish to maintain shape after repeated use. Wear- and heat-resistant markings ensure long-term readability.

This tool provides fast, accurate oil status checks, helping extend service life and ensure reliable KM9 operation.

This component is a critical part of a transmission, installed inside the stator or torque converter to improve power transfer efficiency. In a torque converter, the stator sits between the pump impeller and turbine, controlling hydraulic fluid flow to increase torque at low speeds and reduce losses at high speeds.

This cylinder and piston set is a key power unit in an air compressor, compressing air efficiently. The cylinder guides piston motion and forms the compression chamber, while the piston compresses air to high pressure. Multiple cooling fins on the cylinder dissipate heat, maintaining stable operation in prolonged high-speed, high-pressure conditions. Made from high-strength alloy steel, the piston resists wear and deformation, with multiple ring grooves ensuring airtight sealing and even lubrication. Precision machining minimizes friction, prevents leakage, and maximizes compression efficiency. Corrosion-resistant materials and surface treatments provide long-term stability in marine and industrial environments. Custom manufacturing is available for size, shape, materials, compression stages, and cooling designs, delivering solutions tailored to customer needs.

The connecting rod links the piston to the crankshaft, converting reciprocating motion into rotation while transmitting combustion forces. It is made from gray cast iron or customer-specified materials, selected for engine power, speed, and operating conditions. Production involves precision machining for low surface roughness and strict dimensional tolerance control. After machining, non-destructive testing (NDT) detects micro-cracks or internal defects to ensure durability. Each rod is checked for centerline accuracy, weight balance, and surface quality to maintain stability under high speed and load. Functionally, it transfers and absorbs forces and vibrations from combustion, requiring high strength, wear resistance, and balanced weight. Custom designs can be provided for dimensions, geometry, bearing types, and surface finishes, with prototypes tested and refined to meet customer needs, ensuring durability, reliability, and efficiency in marine and industrial engines.

The Arm, Extractor is a key component in 76mm and 62mm naval guns, responsible for removing spent cartridges after firing. When a case remains in the chamber under high heat and pressure, it grips the rim or groove and, in sync with the extraction system, pulls it free and guides it to ejection.

Built to endure the harsh environment of naval operations, it can be custom-made in various materials and designs per customer requirements. Special heat treatment enhances wear resistance and minimizes deformation during repeated cycles, while optional coatings improve corrosion protection.

Manufactured through precision CNC machining, dimensional inspection, surface finishing, and assembly, each unit passes strict testing for accuracy, strength, and durability, ensuring consistent performance in high-rate, continuous fire. This reliability makes it essential for maintaining operational safety and readiness.

This safety valve for high-pressure air compressors automatically opens to release compressed air when system pressure exceeds the set range, protecting equipment and operators. Designed to operate at 250–300 bar, it can be customized for both operating pressure and external configuration to meet customer requirements.

Operation: When internal pressure reaches the set value, the spring is compressed beyond its limit, lifting the valve disc and opening the passage. Air is discharged until pressure returns to a safe range, then the disc reseats to seal the flow path.

Construction: The valve has a brass housing for corrosion resistance and sealing, and a stainless steel body for strength and wear resistance under high loads and repeated cycles. A threaded connection allows easy installation and removal, while a top adjustment knob enables precise pressure setting.

Performance: Built for marine and industrial use, it resists corrosion, wear, and deformation under long-term high-pressure operation. Available in various specifications for 10–300 bar, it ensures overpressure prevention, equipment protection, and safe operation in demanding environments.
