On April 11, 2019, the Shaanxi Automobile Delong L3000, which was equipped with the Yuchai upgraded YC4EG diesel engine , officially opened the road test. The newly upgraded L3000 has significantly increased power and torque, and the maximum output torque has been increased to 800 N·m. As you can see in the video above, on the day of the road test, the L3000 performed quite amazingly. The speed-up feeling like "Arrowing" attracted the driver's praise.
The new upgraded Yuchai version of Shaanxi Heavy Duide L3000
Delong L3000 is a medium-card product launched by Shaanxi Heavy Duty Truck in 2017. Its listing has ended the history of Shaanxi Heavy Duty Truck only heavy trucks without medium-card products. In the past two years since its launch, DeLong L3000 has become an important emerging force in the express logistics and refined oil transportation market due to its ultra-high performance in the industry. Sales volume has been growing steadily year by year.
The Yuchai YC4EG, which is loaded on the L3000 4X2 model, is a lightweight diesel engine developed by Yuchai and Ricardo in the UK to meet the latest emission standards. The B10 has a life of more than 600,000 kilometers.
Yuchai YC4EG engine
The YC4EG improves the vehicle's power by changing the engine's throttle characteristics, achieving a significant increase in power and torque, further enhancing the advantages of vehicle acceleration and climbing, and effectively improving transportation efficiency. Card friends are undoubtedly a huge gospel.

Since sliding cannot be eliminated in the contacts between the cage and other bearing parts, the cage itself is the first component to be affected when lubrication becomes inadequate. Compare with Steel Cage Spherical Roller Bearing, brass cages have a much higher resistance to adhesive bonding and, for this reason, even in harsh conditions, when lubrication is insufficient, they enable bearings to attain the design rating life.
FEATURE:
The design of Spherical Roller Bearing allows the roller rows in Roller Bearing to run at different speeds, thereby enabling the bearing to absorb high levels of linear deviation. Spherical roller bearings have high radial load capacity, which is especially suitable for work under the heavy load, high shock or vibration load and misaligned loads, but can't afford to pure axial load.
TYPES:
Due to customers` requirements, XKTE can offer different structures of spherical roller bearing, such as steel sheet metal frame structure(C type), brass solid cage structure(CA type/M type)
CC, CA Spherical roller bearings are special bearings, because the energy consumption of such bearings is relatively low, just toughness more advantages. CA, CC Spherical roller bearings can operate freely in high-speed machinery, as well as high rigidity Low-friction precision work in the popular, but also has high bearing capacity so much loved by the majority of users.
Both the dynamic load rating and rating life equations contain no difference regarding cage design and material (brass or steel)
CC Spherical roller bearings equipped with steel cages and operating in conditions of poor lubrication, may lead to adhesive wear and smearing. The hard steel contaminants that may appear, as well as the indentations that may form on raceways and rolling elements, act as locations for surface fatigue
brass cages have a much higher resistance to adhesive bonding and, for this reason, even in harsh conditions, when lubrication is insufficient, they enable bearings to attain the design rating life.
Some spherical roller bearing variants may include perforated outer ring and oil groove features in their design to facilitate easier lubrication and further extending their longevity. with the suffix W33 or H.
APPLICATION:
Spherical roller bearing are available with heavy duty rollers and cages that are suitable for extreme demand harsh applications such as vibratory screens. Mining Conveyor Machine, and mining bulk Conveyor Pulley. In this sort of aggressive operational environment, the spherical roller bearing is the only type that delivers acceptable service life. generally have a longer life span than other bearing types.
