ZYS YRT bearings, also known as rotary table bearings, are axial and radial combined cylindrical roller bearings, including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial pre-load.

ZYS provides high quality bearing products and professional bearing solutions for users in the fields of machine tool, wind power, metallurgy, automobile and rail transportation, construction machinery, etc. ZYS can perform batch production of various bearing products with inner diameter of 0.6mm to outer diameter of 6.8m.

ZYS is engaged in researching the application of bearing antirust lubricating technology for a long time, and has developed various relevant oil and grease products. We undertake the standards establishment and product inspection for non-metallic products, such as anti-rust products, lubricants, plastic cage, seals, etc.

ZYS can mass-produce specialized bearing processing equipment, including CNC bearing ring turning equipment and automatic production lines, fully automatic grinding machines, superfinishing machines, precision cold rolling machines for bearing rings, and semi-automatic multi-purpose grinding machines for small ball bearing rings.

ZYS has made many China national and industrial standards for bearing steels, such as High Carbon Chromium Bearing Steel, High Carbon Chromium Bearing Steel Wire, High Carbon Chromium Bearing Steel Seamless Tube, Stainless Bearing Steel Specification, etc.

ZYS electric spindles are the embedded motor spindles, which drive the shaft directly to work by driving power. So our high frequency spindles reallize the compounding of motor and shaft.

ZYS was formerly known as Luoyang bearing research institute, which was founded in 1958 and was China’s only first-class comprehensive research institute in bearing industry. As it joined in China National Machinery Industry Corporation in 1999, the former institute was transformed into the science and technology enterprise.

ZYS is experienced in the bearing design,selection,installing and maintenance of rolling mill bearings. We have closely cooperated with customers since bearing design stage. We can supply fast and professional service, aiming at greatly improving the bearing performance.
