Detailed Product Description
Ball Bearings are many types of ,Such bearings are self-aligning roller bearings ,Specific purposes are as follows :
Cylindrical roller and the raceway was line of contact, the radial load capacity, which applies to withstand heavy load and shock load, also applies to high-speed rotation N type and NU type can be axial movement, able to adapt due to thermal expansion or installation errors caused by axis and the shell changes the relative position, the most adapted for the free end bearing NJ-type and NF type can withstand a certain degree of unidirectional axial load, NH-type and NUP type can withstand a certain degree of bi-directional axial load of the inner or outer ring detachable, easy to Assembly and Disassembly NNU type and NN-type anti-radial load rigidity strong, mostly for machine tool spindle
Mainly used to maintain frame: steel stamping cage (Z-shaped), copper alloy cutting system, cage, pin-type cage, synthetic resin molding retainer
Main use: medium and large motors, generators, internal combustion engines, gas turbine, machine tool spindles, deceleration devices, handling handling machinery, all kinds of industrial machinery
Type of spherical bearings in the outer ring raceway and inner raceway fitted between pairs of spherical roller, according to the different internal structure, is divided into R, RH, RHA, and four kinds of patterns SR
As the outer ring raceway of circular arc center and bearing center line, with self-aligning properties, it can automatically adjust the shaft or housing deflection or a different axis errors caused by heart
Can bear radial load and bi-directional axial loads. In particular, the radial load capacity, suitable to withstand heavy load and impact load
Tapered bore bearings through the use of fasteners or a withdrawal sleeve allows the shaft of the Assembly and Disassembly
There are two kinds of tapered bore (taper):
1:30 (Auxiliary code: K30) ... ... for 240,241 Series
1:12 (Auxiliary code: K) ... ... ... apply to other series
The outer ring can be opened hole, tank and positioning pin holes (one). Inner ring on the opening hole and the fuel tank can also be
Mainly used to maintain frame: copper alloy cutting system, cage, steel stamping cage, pin-type cage, synthetic resin molding retainer
Main uses: papermaking machinery, deceleration devices, railway rolling stock axles, rolling mill gear box seat, rolling mill roller son, crushing machines, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical seat adjustment with a heart Bearing.
