Heavy Metal Bushings are precision-manufactured components designed specifically for use in throttle valves. These bushings feature a bimetal construction, which combines the strengths of two different metals to create a bushing that is both durable and highly wear-resistant.
The split type design of these bushings allows for easy installation and removal, making maintenance and replacement quick and efficient. The bushings are also equipped with grooves in either the JF800 or JF720 pattern, depending on the specific application requirements. These grooves provide additional lubrication and reduce friction, further enhancing the bushings' performance and lifespan.
The Heavy Metal Bushings are made from high-quality materials that can withstand the high pressures and temperatures commonly encountered in throttle valve applications. This ensures reliable performance even under extreme conditions.
Whether you're looking to replace worn-out bushings or upgrade your throttle valve system, our Heavy Metal Bushings with bimetal construction and JF800/JF720 grooves are an excellent choice. They offer superior performance, durability, and ease of maintenance, making them a valuable addition to any throttle valve setup.
Professional metal and bimetal bearing manufacturer,Bimetal Bearing, Diameter Range : 15 to 130 mm, jf-800 bimetallic bearing, is based on low carbon steel plate as matrix material, surface sintering CuPb10Sn10 or CuSn6Zn6Pb3 steel and copper alloy products.This product is one of the strongest bearing capacity of double alloy bearings, used for the balance bridge bushing of heavy duty vehicles.It is a kind of high - load and low - speed motion bearing.Technical parameters
