Rulmenţi cu contact în patru puncte-click pt redirectionare catalog

Rulmenţii cu contact în patru puncte sunt rulmenţi radiali-axiali cu bile pe un singur rând şi necesită astfel un gabarit axial deosebit de redus faţă de rulmenţii cu bile pe două rânduri.

Aceste lagăre constau din inele exterioare masive, inele interioare secţionate şi din colivii cu bile, din alamă sau din poliamidă. Datorită inelelor interioare secţionate se pot monta un număr mare de bile de rulare. Jumătăţile inelului interior sunt împerecheate şi nu au voie să fie interschimbate cu cele ale unui lagăr identic. Inelul exterior, colivia cu bile şi ambele jumătăţi ale inelului interior se pot monta separat.

Four point contact bearings-click here for catalog

Four point contact bearings are single row angular contact ball bearings and therefore require significantly less space in an axial direction than double row designs.

The bearings comprise solid outer rings, split inner rings and ball and cage assemblies with brass or polyamide cages. Due to the two-piece inner rings, a large number of balls can be accommodated. The halves of the inner ring are matched to the specific bearing and must not be interchanged with those of bearings of the same size. The outer ring with the ball and cage assembly can be fitted separately from the halves of the inner ring.
