6.1 Standard cylindrical bearings / Rodamientos cilndricos estndar Introduccin Product overview / Description Cylindrical roller bearings feature high radial load capacity due to the fact that raceways and rollers are in linear contact. These bearings are well-suited for applications requiring heavy radial and impact loading. They are also appropriate for high-speed apͭplications, in that they can be machined very precisely due to their structure. Both inner or outer rings could be separated, which makes the assembly or disassem-bly easier. An interference assembly is also possible. Design The...

A&sFersa8 Bearings K^Sll N-type bearings have the following features: Caractersticas de los rodamientos tipo N: Two-flanged inner rings. Flat outer ring. Separable components. Adjustment with interference is possible. Dos pestanas de aro interior. Sin pestana en el aro exterior. Componentes desmontables. Ajuste con interferencia es posible. Both NU and N executions exhibit their best performance when used as free side bearings since they adjust to the shaft's axial move-ment relative to the housing position. NUP-type bearings have the following features: - Two-flanged outer ring. - One-flanged...

6.1 Standard cylindrical bearings / Rodamientos cilfndricos standard Misalignment Fersa produces cylindrical roller bearings with modified geometry to minimize contact stresses between rollers and ring raceways. The ability of single row cylindrical roller bear-ings to accommodate angular misalignment of the inner ring with regards to the outer ring is limited between 2 and 4 angular minutes, depending also on bearing type and specification. Internai clearance Fersa single row cylindrical roller bearings are manufactured with normal radial clearance as standard, but most of the references are...

A&sFersa8 Bearings K^Sll Equivalent dynamic bearing load When cylindrical roller bearings are used as non-locating bearings, type N, NU, they are unable to support any thrust loads, therefore the applicable formula is: Carga dinmica equivalente del rodamiento Cuando los rodamientos de rodillos cilndricos se usan como rodamientos libres, tipo N, NU, ya que no pueden soportar cargas axiales, la formula aplicable es: P = Fr En el caso de los rodamientos con pestanas en aros interiores o exteriores, la carga din⮢mica equivalente del rodamiento debe calcularse como se detalla a continuaciʹn: P = Fr cuando...
