| Hard Metal Tappet | Feature : 1.Cam and Tappet Movement in Value Train System : - Contact between Cam and Tappet Line Contact, Rolling with sliding Orowned surface of tappet (for uniformwear) 2. Lubrication :- Cam Base Area : Hydrodynamic lubirication Cam Nose Area : Boundary lubrication 3. Reliability of Tappet Bonding Ultrasonic test of bonded parts Last 3 years, mass prodution of Hard Metal tappet,There's no apart of bonded part. Quality assurance system of tappet produced, it has a reliability. 4. Mass Production technical Alliance with the I.M.U High technology posseession enterprise. Tere's no Quality Problems in mass production of Hard Metal tappet for 5 years 5. Rig Test(Motoring)- Pitting The alloy i appets have pitting & all of them have not shown crowned shape. Hard Metal tappets have no pitting & remain crowned shape |
| PEM (Pressed Embossing) bushing | A high performance bushing: A plurality of embossing formed on the inner circumferential surface serves as a grease reservoir and making grease spread widely during operation to form an oil film between the pin, providing excellent anti-friction/wear characteristics Rig test methods and results :- Load-bearing property: Load (PEM: 6.7kgf / ? or above/ Carburization: 2.3kgf / ?) Durability (non-feeding): Measurement of cycle of burning-in after feeding one time in the pitching mode(90 degrees) (PEM: 23,000 cycles / carburization: 38,000 cycles) Wear amount of bushing: Thickness of wear after test in the section of burning-in (PEM: 0.01 mm / Carburization: 0.096 mm) |
