Cerinţele impuse mecanismelor de tip şurub-piuliţă nu pot fi întotdeauna îndeplinite de rulmenţii standardizaţi. INA/FAG deţine o paletă vastă de rulmenţi axiali-radiali cu bile pentru suspensiile exacte, rigide, cu frecare redusă, uşor de montat şi fără întreţinere care îndeolinesc necesităţile de funcţionare dinamice ale mecanismelor de tip şurub-piuliţă. Cu acest spectru de produse se pot soluţiona toate aspectele tehnice şi economice ale suspensiei şuruburilor de avans din orice aplicaţie.

variante pe mai multe rânduri

Rulmenţii axiali-radiali se execută în mai multe variante constructive cu bile pe unul, două sau pe trei rânduri şi sunt ansamble gata de montaj. Aceştia sunt nedemontabili şi se compun din inele exterioare cu pereţii groşi, din colivii cu bile şi din inele interioare monobloc sau secţionaţi. La multe variante constructive, inelul exterior prezintă o flanşa cu orificii pentru montajul simplu la construcţia învecinată. Inelele lagărului sunt astfel construite încăt pot fi pretensionate cu ajutorul unei piuliţe crenelate de precizie.

Bearing arrangements for screw drives are subject to requirements that often cannot be optimally fulfilled by conventional bearings due to their design construction. For the design of maintenance-free or low-maintenance bearing arrangements for the highly dynamic operating conditions of screw drives that are precise, have high load carrying capacity, high rigidity and low friction and are easy to fit, INA/FAG maintains a wide range of axial angular contact ball bearings. With this highly developed product range, the best application-specific solution can be found for all the technical and economic requirements placed on screw drive bearing arrangements.

Multi-row designs

Axial angular contact ball bearings are available in single row, double row or triple row ready-to-fit units. They are self-retaining and comprise thick-walled, geometrically stable outer rings, ball and cage assemblies and single-piece or two-piece inner rings. In several series, the outer ring has through holes for straightforward flange mounting of the bearing to the adjacent construction. The bearing rings are matched to each other such that a defined preload is achieved once the rings are clamped by means of a precision locknut.
