Product Description

 

Product Description

Cylindrical roller bearings with inner or outer rings without fenders, whose inner and outer rings can move relative to each other in axial direction, can be used as free-end bearings. Cylindrical roller bearings with double rim on one side of the inner and outer rings and a single rim on the other side of the ring can withstand a certain degree of axial load in one direction. Generally used steel plate stamping cage, or copper alloy car solid cage. But some use nylon forming cages.

Cylindrical roller and raceway for line contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling body and the rim of the ring is small, suitable for high-speed rotation. According to whether the ring has a rim or not, it can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings. The bearing is a detachable structure with inner ring and outer ring.

Adhering to the business philosophy of "Quality and Integrity", we will continue to provide excellent bearings and high-quality services to serve global customers.

Our Advantages

With a professional team and advanced manufacturing technology, it is in a leading position in the research and development of slewing rings and customized bearings, with reasonable design structure, light weight, strong bearing capacity and strong versatility. Bearing diameters range from 200 to 15000mm, with accuracies covering P0, P6 and P5 grades. Our slewing rings, precision bearings and custom bearings are used in a wide range of industries including construction, engineering, mining, marine, chemical, wind turbines, medical equipment etc.

Solutions

 

Playground Equipment

Slewing bearing can provide excellent performance experience and safety guarantee for amusement equipment, and the durability of slewing bearing is also the main concern of technical engineers. For more than 20 years, slewing bearing solutions have been used in many key applications of large amusement equipment. reflect.

We designed the cross-sectional area to remain the same as the raceway center distance increased, and the slewing ring achieves better dynamic capabilities with less mass.

Key advantages include:
* Lighter weight
* Save spaighter weightce
* Long life and lower maintenance costs
* Better stiffness
* Better lubrication in extreme conditions

Medical Device
With the comprehensive development of scientific and technological strength, the social economyu has been improved faster, and the medical equipment has also been comprehensively improved.

Mining & construction machinery

Mining machinery and heavy construction machinery industry uses a range of different types of highly specialized mobile machinery. . The places where mining machinery and construction machinery are active are mostly mining sites such as mountains and deserts that are far away from ordinary human life. These heavy machinery work in the harshest environments and require continuous low-friction work without reducing load capacity and minimum. assembly and adjustment time. Solving the bearing heating problem caused by the large exciting force, high vibration frequency and continuous operation of vibratory rollers for users has become the focus of the work. Mineral crushing machinery, cutting machinery, screening machinery, loading machinery, conveying machinery and other equipment in the use environment of bearings, users desire products with robustness, durability and high reliability to resist these harsh working conditions.

Transportation vehicle

Metric and inch needle roller bearings have various structural types, mainly including open drawn cup needle roller bearings, closed drawn cup needle roller bearings, needle roller bearings with inner ring and needle roller bearings without inner ring/without inner ring Cage needle roller bearings, caged and cageless needle roller bearings. Widely used in automobiles, motorcycles, mopeds, power tools, textiles, agricultural machinery, printing machinery, construction machinery, automatic instruments and other fields.

Automatic machinery

Industrial robot bearings mainly include two categories: one is thin-walled bearings, and the other is crossed cylindrical roller bearings. In addition, there are harmonic reducer bearings, linear roller bearings, spherical plain bearings, etc. Bearings with good performance have large bearing capacity, good rigidity, high rotation precision and easy installation.
