|
21310 Long Use Life Spherical Roller For Machine Tool Spindles
1 . Spherical roller bearing
1 . production range Inner diameter :10 mm ~ 1100 mm Outer diameter : 30 mm ~ 1300 mm Height 9 mm ~ 300 mm
Spherical roller bearing has two columns of roller , mainly bear radial load , but also can carry axial load in either direction . Have high radial load capacity , especially suitable for overloading or under vibration loading work , but can't afford to pure axial load . This kind of bearing outer ring raceway is spherical shape , so the self-aligning performance is good , can compensate the alignment error
2 . Other size
4 . Package
1 . Usually made by plastic+anti-rust paper+box+wooden box
5 . Appliexcavatorion : The self-aligning ball bearings are widely used in mining machinery , power machinery , heavy machinery and textile machinery etc .
