Chinese Professional Car Interior Accessories - Auto spare parts crankshaft for Perkins GDA 404 with Oem Number 115256750 for factory price – SAMUEL

Description

It is suitable for Perkins 404, high-quality manufacturing technology, to ensure the service life of the product. Our factory has more than 30 years of production experience and strong production capacity to ensure timely delivery.

In order to reduce the mass of the crankshaft and the centrifugal force generated during movement, the crankshaft journal is often made hollow. Oil holes are formed on each journal surface to facilitate the introduction or extraction of engine oil to lubricate the journal surface. In order to reduce the stress concentration, the joints of the main journal, crank pin and crank arm are all connected by transition arc.

The product is made of high-strength ductile iron and forged steel, and is treated with surface strengthening technology to improve the fatigue strength of the crankshaft. It is suitable for automobiles, ships, engineering vehicles, agricultural machinery, generator set，original quality, with good appearance, high density, smoothness, brightness and durability after finishing. Each product has undergone rigorous testing and its quality has been guaranteed. Box packaging has a good appearance and durable production cycle: 20-30 working days, neutral packaging/original packaging, mode of transportation: land, sea and air.

The crankshaft is the most important component in the engine. It withstands the force transmitted by the connecting rod and converts it into torque output through the crankshaft and drives other accessories on the engine to work. The crankshaft is subjected to the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, which makes the crank bearing subjected to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance.
