Rulmenţi axiali cu role cilindrice

Rulmenţii axiali cu role cilindrice sunt formaţi din colivii axiale cu role cilindrice, inele de carcasă şi din inele de arbore.
Aceştia au o lăţime axială deosebit de redusă, au capacitate portantă foarte mare, sunt rigizi şi preiau forţe axiale într-un singur sens.

Colivii axiale cu role cilindrice

Coliviile axiale cu role cilindrice se compun din coroane axiale cu unul sau două rânduri de role cilindrice. Coliviile au o lăţime axilă deosebit de redusă, sunt foarte portante şi foarte rigide. Preiau forţe axiale dintr-un singur sens şi acţionează în direcţie radială ca lagăr liber. Coliviile axiale pot fi combinate cu inele de carcasă, respectiv de arbore sau pot fi integrate direct în construcţia adiacentă. Dacă se folosesc fără inele axiale, căile de rulare ale construcţiei invecinate trebuiesc să îndeplinească calităţile căilor de rulare pentru rulmenţi.

Inele de carcasă

Inelele de carcasă sunt fabricate prin aşchiere, suprafaţa exterioară este rectificată iar suprafaţa de rulare este prelucrată fin. Se pot centra pe diametrul exterior şi se combină cu colivii axiale dacă suprafaţa învecinată nu poate fi folosită ca şi cale de rulare.

Inele de arbore

Inelele de arbore sunt fabricate tot prin aşchiere, suprafaţa interioară este rectificată iar calea de rulare este prelucrată fin. Se pot centra la diametrul interior şi se combină cu colivii axiale dacă suprafaţa învecinată nu se poate folosi ca şi cale de rulare.

Inele rotative

Inelele rotative se pot folosi atât ca şi inel de carcasă cât şi de arbore. Diametrul interior şi exterior sunt strunjite iar calea de rulare este rectificată.

Axial cylindrical roller bearings

Axial cylindrical roller bearings comprise axial cylindrical roller and cage assemblies and shaft and housing locating washers.

The bearings have particularly small axial section height, have high load carrying capacity and high rigidity and can support axial forces in one direction.

Axial cylindrical roller and cage assemblies

Axial cylindrical roller and cage assemblies comprise axial cages with one or two rows of cylindrical rollers. The cage assemblies have particularly small axial section height, high load carrying capacity and high rigidity. They can support axial force from one direction and act as non-locating bearings in a radial direction. Axial cage assemblies are combined with housing or shaft locating washers or are integrated directly in the adjacent construction. If they are used without axial bearing washers, the raceway must be produced as a rolling bearing raceway.

Housing locating washers

Housing locating washers are produced by machining, the outside surface is ground and the running surface is high precision machined. They are housing located and are combined with axial cage assemblies if the adjacent surface cannot be used as a raceway.

Shaft locating washers

Shaft locating washers are produced by machining, the bore is ground and the running surface is high precision machined. They are shaft located and are combined with axial cage assemblies if the adjacent surface cannot be used as a raceway.

Bearing washers

Bearing washers can be used as housing and shaft locating washers. The bore and outside surface are turned, the running surface is ground.
