FAQS

QWhat are THE ADVANTAGES OF CERAMIC BALL BEARING?

AFirst, because ceramics are almost not afraid of corrosion, so ceramic rolling bearing is suitable for operation in the harsh conditions full of corrosive media. Second, because the density of ceramic rolling ball is lower than that of steel and its weight is much lighter, the centrifugal effect on the outer ring can be reduced by 40% during rotation, and the service life can be greatly prolonged. Third, ceramic is less affected by thermal expansion and cold shrinkage than steel, so when the bearing clearance is fixed, the bearing can be allowed to work in the environment with more drastic temperature difference changes. Fourth, because the elastic modulus of ceramic is higher than that of steel, it is not easy to deform when it is stressed, so it is beneficial to improve the working speed and achieve high precision.

QWhat are THE APPLICATION FIELDS OF CERAMIC BALL BEARING?

AMedical equipment, low temperature engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery. In the fields of aerospace, navigation, nuclear industry, petroleum, chemical industry, light textile industry, machinery, metallurgy, electricity, food, locomotive, subway, high-speed machine tool, scientific research and national defense military technology, etc., it is necessary to work under special working conditions such as high temperature, high speed, deep cold, flammable, explosive, strong corrosion, vacuum, electric insulation, non-magnetic, dry friction, etc., and the indispensable substitution function of ceramic bearing is positive. It is gradually recognized by people. With the continuous progress of processing technology and the increasing level of technology, the cost of ceramic bearings has been continuously reduced. It has been applied in a small range in some high, fine and sharp fields in the past, and gradually extended to various industrial fields of national economy. The market price of products is also gradually approaching the practical application, reaching the level acceptable to users. The wave of large-area application of ceramic bearings has come!

QWhat is REXROTH PUMP?

ARexroth hydraulic pump is a brand product of Bosch Rexroth. Rexroth is not only one of the top 100 companies in the world, but also one of the world's famous high-tech enterprises. Over the past 50 years, the business departments of Bosch Rexroth group and Bosch Rexroth company have been committed to the development of professional high-tech products in the field of hydraulic transmission, and the products and brands have gained worldwide reputation. Rexroth's products are unique because there are no other brands in the world market that can provide customers with all the transmission and control technologies, specialization and integration at the same time. For this reason, Bosch Rexroth has become a world model in the fields of hydraulic transmission, control and mobile technology.

QWhat are THE CHARACTERISTICS OF THE REXROTH PUMP?

A1) the flow of the pump is directly proportional to the speed and displacement of the pump, and the displacement can be adjusted steplessly by adjusting its swashplate angle. 2) coaxial structure can form combined pump 3) position constrained return structure 4) spherical distribution, plunger arranged around the main shaft 5) stepless variable 6) excellent suction capacity 7) short control time 8) low noise 9) long life 10) excellent power / weight ratio 11) modular design
