Cylinder Liner

We supply Cylinder Liners from experienced and innovative quality system for 2-stroke and 4-stroke engines. We are available with cylinder bore from 260mm up to 700mm. Cylinder Liner is one of the key components for the proper operation of the engine and costly item which required periodically exchanged caused wear-out by piston motion. So you should make choice reliable product with high-quality material and strict process.

Cylinder Cover

We supply Cylinder Cover with superior quality for 2-stroke and 4-stroke engines. We are available with cylinder bore from 165mm up to 600mm and especially keeping many stocks for 4-stroke engines.

Cylinder Crown

We supply various Piston Crown for 2-stroke engines. We are available with cylinder bore from 280mm up to 600mm. Piston Crown is one of the components for combustion chamber along with Cylinder Liner, Cylinder Cover. Piston Crown absorbs compression and explosion power and piston rod can be performed up-stroke and down-stroke in the cylinder liner. The material of Piston Crown is Steel Forging.

Fuel Injection Engine Parts

• Nozzle Tip & Atomizer
• Fuel Injection Valve & Pump Assembly
• Plunger & Barrel Assembly
• F.O / Exhaust / Intake CAM
• Delivery Valve
• Tappet Roller & Roller Guide / Pin


Drum Type

a.) Very economical, reliable equipment which is widely used for many kinds of ships and oil-tankers, industrial machinery. (press, shearing, bending, forming, printing, packing metal working, construction, gold shear, flying shear, etc.)

b.) Aluminum shoes help the ventilating. Especially, easy to assemble and repair with simple structure.

c.) Easy control to transmit the power. Used for Tension Brake and machine which required slip conditions around shaft by periods.

d.) Used as shaft couplings or holding brake for Laundry
Machines, Textile Machines, etc...

Piston Type

a.) Clutch and Brake unit structure. Easy assembly and changing linings. Protect mold base and work safety with fast braking system.

b.) Suited for Tension Brake and soft products. Effective heat emission, makes possible compulsory cooling.
Easy assembly and changing linings.

c.) Braked by spring and worked by air pressure. Safe working with automatic brake in case of power cut or low air pressure situation.

d.) Only for clutches and transfer torque softly. Can be used in high speed and high temperature. Effective heat emission and have a long life.

e.) Suited for control at middle of shaft. Clutch and Brake unit structure. Protected from heat with disc's cooling fan of clutch and brake. Endurable and firm, also smooth working.

f.) Doesn't need gear concentricity to assemble because of unit structure. Can install without allowance errors because it is assembled around shaft. Can be used in damp or dryness situations.

a.) Standard Torque Disc Clutch or Brake     b.) High Torque Disc Clutch or Brake     c.) Spring Set Disc Brake     d.) Ventilated Disc Clutch
                                e.) Water Cooled Disc Brake     f.) Copper Cooled Disc Brake     g.) Copper Cooled Studded Brake
