When you visit our company, we could fully show you the detailed inspection process & quality control process of the thin wall bearings.
Thin wall bearing means the section of the bearing is smart & slim, which could save space.
The thin wall bearings usually used in the area that small space same load as the normal bearing.

We know that the Swedish SKFball bearing Group is very concerned about its impact on the environment, and in 1989 released the first environmental policies. May 21, we learned from SKF bearings distributor in China, SKF and China State Forestry Administration of China signed a framework agreement in remote areas of afforestation. SKF investment through Chinese forest planting projects, hoping the field of environmental protection and social responsibility to contribute to the local community. SKF forest planting projects to invest in China held in Beijing, "Sweden and China Innovation Week" kick-off ceremony was held at the signing ceremony, the project is expected to last five years. SKF has been selected forest industry's leading research institutions - the Swedish University of Agricultural Sciences (SLU) as a technology partner. SKF Group President and CEO Tom. Johnstone SKF investment in China's forest plantation project signing ceremony, said: "We have always been committed to manufacturing operations to reduce the negative impact on the environment, while providing customers with new environmental value technology, new products and services and we know that the forest in the ecosystem plays a vital role in this project for the sustainable development of our work and bearing roller zero plan is a favorable support. " With environmental and ecological awareness in SKF's daily operations have always played an important role. SKF in 1989 promulgated the company's environmental policy. SKF is the first to obtain ISO14001 certification of multinational companies worldwide, covering 17 countries, 63 units of departments. China's goal is to 2050 the forest coverage of more than 26%. SKF has a strong sound processes that can continually improve manufacturing operations and production equipment energy efficiency. Therefore, we can greatly reduce carbon dioxide emissions. Over the past four years, reduce carbon dioxide emissions by 27%, a decrease of 150,000 tons.

In principle, all NSK bearing roller prior to installation should be kept in their original packaging. They need to stay in a clean, moisture free, relatively constant temperature in the environment. Rolling NSK Bearings should stay away from dust, water and corrosive chemicals. Shaking and vibration may forever destroy the mechanical properties of NSK bearings, so the handling and storage process must avoid vibration.Basically, all levels of NSK bearings have to be saved, because some heavier NSK Bearings long vertically, it may be deformed due to its own weight.Pre-coated with grease (or sealed) NSK bearings need to be careful, because the oil after a long period of storage after the density change. NSK bearings so that when the first time, there will be a certain degree of rotation noise. Thus, the NSK thin bearings aside time should be controlled according to the FIFO principle.CleanClean the rolling NSK bearings is very important. NSK Bearing ring rolling surface and the rolling elements of the surface roughness is typically 1/10 μm, such a smooth surface of pollutants are very sensitive to damage. A lubricating layer between the rotating surface is generally 0.2 ~ 1 μm, a particle size larger than the lubricant-type impurity will be rolled over the rolling element bearings in the NSK partial pressure produced in steel, fatigue will eventually cause permanent. In addition to this, the external environment in the dust particle size of up to 10 μm, NSK bearings will also cause damage. Therefore, clean dust-free environment for NSK Bearings storage and installation is critical.Fully prepared to installNSK Bearings should carefully using a suitable tool installation and removal. Industry experts estimate that premature failure of NSK Bearings 16 percent of cases are due to incorrect installation. For large installations (for example in the production of the device) is concerned, usually installed strictly controlled conditions, you can use the appropriate NSK bearings installed equipment.However, in the maintenance or replacement work, the environment is varied. Therefore, to ensure the longest life of NSK bearings, comprehensive preparatory work on NSK Bearings installation is necessary.First, the relevant documents, such as drawings, maintenance manuals, brochures and other products require careful study. Next, all NSK Bearings components, such as shafts, the distance ring, cover, washers, etc. must be kept absolutely clean and free from contamination. Adjacent parts of the state should be carefully examined.Careful installation and removal
Crossed roller bearings rotating at high speed burns failure analysis |

In bearing burn injury status means: wheel bearing raceways, rolling elements and cage sharp fever in the rotation until discoloration, softening, deposition and breakage. Bearing burns caused mainly due to poor lubrication of bearings, may not be using regular lubricant or lubricant too much, too little, is not correct. Secondly may be too large loads (preload is too large). Speed is too large. Clearance is too small. Water or other foreign matter intrusion. If the above two conditions are not so that shaft, bearing housing poor precision, shaft deflection.
cross roller bearing rotating at high speed, especially speed close to or exceed the size limits listed in the table speed, the use of bearings matters:
(1) Analysis of Lubrication: use for high-speed rotation of the circulating lubrication, spray lubrication, oil mist lubrication and oil lubrication lubrication.
(2) analysis of the bearing internal clearance: Consider the temperature rise of the bearing internal clearance reduction.
(3) the material of the cage type: For high-speed rotation, suitable for cutting copper alloy or phenolic resin cage. There is also suitable for high speed rotation of the synthetic resin molded cage.

Thin ring bearing, high precision, very quiet and very strong bearing capacity. And extremely small, most of the cross-section is square. In these series, even the larger shaft diameter and the bearing bore, a cross-section remains unchanged. These bearings are therefore referred to other sections (CS). It is this feature of the standard ISO series thin ring bearing with conventional bearings to distinguish.Thus, a larger cross section can be selected using the carrying capacity greater shaft diameter without changing the bearing. Thin ring bearing the extremely light and can be designed to require very little space bearings. Thin ring bearing deep groove ball bearings can be (C), four point contact bearings (X), angular contact ball bearings (E). In different series are available in all of these designs. Series depends on the size of the cross section, the ball and series match.Thin radial contact ball bearings, designed to withstand the high pressure of deep groove ball bearings, 670,068,006,900 series thin wall bearings structure is simple, easy to use, is the largest production volume, most widely used of a class of bearings. Mainly used to bear radial load, but increase the bearing radial clearance, with a certain angular contact ball bearing performance, the axial bearing clearance range, limit the axis or axial housing in both directions displacement, it can be in the bi-axial positioning. In addition, the class also have some bearing self-aligning capability, when compared to shell-hole tilt 2 'to 10', still working properly, can withstand radial and axial joint load. Should not be used in high speed and thrust ball bearings, can also be used to bear pure axial load. With the same size compared to other types of bearings, such bearings friction coefficient, high speed limit. But the impact of intolerance, unfit to bear heavy loads.
