Every powerful engine depends on precision — and the valve tappet plays a vital role in ensuring perfect timing, smooth operation, and consistent performance. At LONMAR, we understand that the smallest engine components often make the biggest difference. That’s why we provide a full range of high-quality valve tappets for global customers across the agricultural, industrial, and construction machinery sectors.
With decades of experience as a trusted Engine Valve Tappet Supplier, LONMAR delivers exceptional products designed to meet OEM standards for major engine brands, including Cummins, Perkins, Deutz, and John Deere.
The Role of the Valve Tappet in Engine Efficiency
A valve tappet , also known as a cam follower or valve lifter, transfers the camshaft’s motion to the engine valves, ensuring accurate timing and smooth valve operation. Precision in this component determines the overall engine efficiency, fuel economy, and durability. A well-made tappet minimizes friction, reduces wear, and maintains consistent valve clearance — essential for long-term engine health.
LONMAR’s Valve Tappet for tractor engines and Valve Tappet for agricultural machinery are built to handle the demanding conditions of continuous field and heavy-duty use. Each tappet is manufactured using premium-grade steel, precision machined, and heat-treated for optimal hardness and wear resistance.
