At present, China deep groove ball bearings and seal products advanced parameters are almost the same internal structure, but such products in China the level of vibration and noise are very different and foreign products, mainly in the manufacturing and working conditions and factors. From the bearing industry perspective, condition factor may make reasonable requests to resolve the host,

1: ntn bearing cleaning focus:1, cleaning the surface of the object stateSmooth surfaces and rough uneven surfaces cleaned the same way, the effect achieved is very different. In the choice of cleaning method should fully take into account the surface conditions.2, the situation of dirtDirt to be used for different a different cleaning agent for metal surface with oil-based dirt and to scale, oxide-based dirt the selected cleaning agent

1, ntn bearing requirements for the workOne of imports bearing loadBearing loads suffered import size, direction and nature of the choice based primarily on imported bearing type.The size selection based on load bearing type of imports, because imports of roller bearings between the main component is line contact, should be used to bear a larger load, the deformation after the load is also smaller. The ball bearings are mainly imported point contact,

1, ntn bearing nature of the noise datantn bearing nature of noise is the use of modern processing technology made bearings will occur,NTN Bearing determined the structure of the noise itself.Nature of acoustic noise can be divided into roller, ball impact and jarring sound of three kinds of sound, are as follows:(1) ntn roller bearings roller sound and control noise when running NTN Bearing imports,

1, ntn bearing installation program(1), cleaning bearings NTN bearings and related department(2) to check the size of related components and finishing conditions(3), the installation(4), installed after the inspection NTN Bearings(5), the supply of lubricantIn the forthcoming pre-installation, it would only open the NTN bearings imported packaging. General grease lubrication, not clean, direct filling grease. Oil lubrication,

1, ntn bearing heat knowledge  ntn bearing the core component, the spindle cell component usually μm-level precision, such as the beating is generally 1 ~ 3μm, spindle stiffness generally 100-300N/μm, therefore, spindle precision of the various parts and their deformation is small. However, the high-speed operation, the bearings much heat, resulting in a high bearing temperature rise and cause thermal deformation.

Rod ends consist of an eye-shaped head with integral shank which forms a housing for a standard spherical plain bearing. As a rule, rod ends are available with left or right-hand female (internal) or male (external) threads to ISO 965/1: 1980. BEARING rod ends which require maintenance are available as standard with the sliding contact surface combinations steel-on-steel and steel-on-bronze

Radial spherical plain bearings are designed primarily to carry radial loads and handle moderate misalignments. we can supply the following types of radial spherical plian bearing.
