ntn japan bearing Rolling bearing structure and features
1. Structure and classification
ntn japan bearing Rolling bearings generally consist of rings, rolling elements, and cages. According to its load direction can be divided into, radial bearings and thrust bearings.
According to the type of rolling element, it is divided into ball bearing and roller bearing. And can also be classified according to its shape and specific use.
2. Structure and characteristics
Compared with plain bearings, ntn japan bearing rolling bearings have the following features:
(1) The starting friction is small, and the difference from the dynamic friction is also small.
(2) Standardization and normalization are promoted internationally, so they are interchangeable and can be used interchangeably.
(3) Simplify the structure around the bearing for easy maintenance and inspection.
(4) Generally, radial load and axial load can be accepted at the same time.
(5) It is relatively easy to use at high and low temperatures.
(6) In order to increase the rigidity, it can be used even in a negative clearance (preload state).
Select ntn japan bearing structure
1. ntn japan bearing space and bearing structure
Permissible for the design of the rolling bearing and its surrounding space is limited. Must choose the bearing structure, the size within this limit scope. First mechanical design
Since the shaft diameter is determined, when the bearing is selected, the bearing inner diameter is the reference. Rolling bearings have many standardized series of sizes and structures from which
Select the most suitable bearing structure.
2. Load and bearing structure
The basic rated load representing the ntn japan bearing load capacity and the available thrust load capacity were compared with the bearing structure. Comparison of bearings in the same size series
Below, ntn japan bearing roller bearings have higher load capacity than ball bearings and are suitable for applications with impact loads.
