After many years of innovation and development, Fast double twinaxes transmission has been developed from a series of three varieties introduced in the current year to more than 20 series of hundreds of varieties. More than 30 patents have been obtained and achieved from a single 9-speed. The comprehensive coverage from the 5th, 6th, 7th, 8th, 9th, 10th, and 12th and 16th gears fully meets the development needs of the Chinese heavy-duty auto industry.
Since the production of the twin countershaft transmissions in 1990, it has taken 17 years for the first million units to go offline, and it has only taken 2 years and 2 months to achieve the second one million units. The product has a market share of more than 8 tons of heavy-duty vehicles in China and has been selected as a fixed-point supporting product by more than 100 models of domestic OEMs. It is also widely exported to the United States, Australia, Eastern Europe, South America, Southeast Asia, and the Middle East. Countries and regions. All operating indicators ranked first in China's gear industry for seven consecutive years.

Hydraulic Support System Seals
Hydraulic support seal
The seal of the Saifu lever hydraulic support is composed of a sealing ring, a retaining ring, a guide ring and a dustproof ring.
Sealing ring:Prevent leaks. Used in the category of hydraulic supports: drum ring, composite seal, mountain ring, bud ring, O-ring, etc. Generally rubber, polyurethane material.
Used together with the sealing ring, it has the functions of anti-crowding, guiding and reducing wear. It is generally made of phenolic XII cloth, 45% copper powder mixed with filled PTFE and other materials.
Guide ring:
It is a part used on the jack piston or piston rod to support the movement of the piston or piston rod. It can prevent the piston or piston rod from direct contact and friction with the cylinder during the movement, and protect the cylinder and the piston or piston. The rod is not damaged. Generally, it is polyoxymethylene, polytetrafluoroethylene and other materials.
Dust-proof ring: the main function is to go out and reciprocate the piston rod to expose the impurities attached to the outer surface of the cylinder, so as to prevent impurities such as external dust from entering the inside of the sealing mechanism. Generally rubber, polyurethane and other materials.
