Our company specializes in the production of combined roller bearings 4.055+AP1-LUB,which are conventional structural roller bearings with a unique design of an oil filling hole on the side of the iron plate.
Standard Fixed combined bearing 4.055,MR0022,0.072202.N,5.996068.Z,4.951316.W Welded on flange plates rectangular with lubrication.
This humanized design facilitates regular lubrication and maintenance, effectively extending the service life of the bearing and ensuring stable operation in long-term work.
The outer ring of the compound roller bearing is made of 20CrMnTi steel with surface hardening treatment, and its hardness reaches 58-62 HRC. This material and treatment method give the outer ring excellent wear resistance, impact resistance and load-bearing capacity, making it suitable for various harsh working environments.
The inner ring is made of high-quality Gcr15 bearing steel, with the same hardness of 58-62 HRC as the outer ring. Gcr15 steel has excellent toughness and dimensional stability, which can ensure the high precision and smooth operation of the bearing, reducing friction and noise during operation.
The welding bolts of the bearing are made of C20 steel, which has good weldability and mechanical strength, ensuring the firm connection between the bearing and the equipment, and avoiding loosening during high-speed operation.
The standard working temperature range of the bearing is -20°C to +100°C, which can meet the needs of most industrial working conditions. In addition, we also provide high-temperature resistant models that can work stably in an environment up to +250°C, suitable for high-temperature working scenarios such as metallurgy and chemical industry.
Our combined roller bearings are manufactured with strict quality control, with reliable performance, long service life and competitive price. They are widely used in machinery, automation, logistics and other fields. We welcome customers from all over the world to cooperate with us and provide customized solutions according to your specific needs.
