Brand: NTN

Name: NTN E – type cylinder roller sub bearing

Type: 51313

About products:

Large axial load get away sub bearing (HT type) with cylinder ,Through enclosing blocking inside and outside the improvement and shape of the sub terminal surface of rolling, further increase the axial load that can be born.

The products are detailed:

NTN E – type roll cylinder it is sub bearing,the same as ordinary bearing in sizes main, be rolled there aren’t diameters, length, number sub, bear load ability to increase correspondingly. Add symbols ” E” On the basic bearing number in order to distinguish. As to big load ability, its design is very light. Because internal diameter different from standard bearing bearing this, can’t exchange large axial load get away sub bearing (HT type) with cylinder ,Through enclosing blocking inside and outside the improvement and shape of the sub terminal surface of rolling, further increase the axial load that can be born. Pair list cylinder, roll sub bearing, type of NN offered, the NNU type. Use for, require thin the intersection of wall and the intersection of lathe and main shaft of bearing more generally, steel rolling roll of motor vehicle and print mechanical the intersection of printing and cylinder,etc.. The lathe main shaft adopt more bearings with hole of the awl of inner circle, install it on the axis of cone, adjust the backlash of radial through the pressing amount of the inner circle. Four cylinder roll sub bearing, used mainly in the intersection of rolling mill and the intersection of roll and neck, the roller neck is within the range of space that it allows, want the great specified load of the bearing amount, so the bearing also needs to design for this. NTN produce special the intersection of bearing and the intersection of Model SL and cylinder, roll sub bearing too, get away son type overweight load bearing while being full. NTN bearing code introduced completely big: -A: Have pair enclosed to isolate list taper, get away sub bearing X: Four points contacting X (n) of the ultrathin ball bearing : Pour the angle specially, n begins to arrange downwards from 1 sequentially; Testing type, n begins to arrange Y downwards from 1 sequentially: Yellow copper presses and keeps the shelf; The angle contacting Z of the ultrathin ball bearing: Wear the stencil plate and press the dustproof lid Z1 only: Wear, become rusty just stiff to press, stamp ZA while being dustproof only: Wear and can dismantle only ‘ There are cards that are enclosed) Stencil plate press prevent dust build ZA1: Wear and can dismantle only ‘ There are cards that are enclosed) Stencil plate press prevent dust build ZS: Put the intersection of ball and the intersection of gap and one side, have stencil plate press, stamp while being dustproof, large load dark the intersection of ditch and ball bearing; In the intersection of backlash and interchangeable the intersection of radial and backlash that compress under group of limiting, cylinder get away sub bearing, accord with the motor standard DIN43283
