Combined cylindrical roller/ball Slew Rings can accommodate the same heavy axial loads as triple row roller slewing bearings in one direction only, but cannot accommodate the same degree of tilting moments. They are suitable for heavy- duty applications, but are as sensitive as triple row bearings to surface imperfections. Combined cylindrical roller/ball Slew Rings consist of two one-piece rings and normally have axial internal clearance. The balls are inserted into the bearing via a hole in one of the two rings and are separated by polyamide spacers.

Operating conditions:

Permissible temperature range -25°C to +70°C

Maximum permissible rotational speed nperm= 40000 / DL

For horizontal rotational axis nperm = 20000 / DL

(DL = raceway diameter)

“Compressive”± load

Bolt grade 10.9

Typical applications:

Reclaimers, stackers and other equipment for bulk materials handling,turntables.

Characteristics:

--High axial load capacity

--Long service life if mainly axial loads

--High rigidity

--Good running precision
