Axial-Radial-Cylindrical Roller Bearing (ARL-E®) - Detail

Product Information

The axial-radial cylindrical roller bearing of the ARL-E® series from IBO is a roller bearing ideally suited for the application in rotary tables and rotary tables for machine tools. With the introduction of the E version, IBO offers a product that represents the state of the art in the field of rotary table bearings.

The axial-radial bearings are two-sided working rolling bearings and have a screw connection with a guiding radial rolling bearing. These ready-to-install pre-greased units have a high degree of rigidity, high load rating and work particularly precisely. These rolling bearings absorb radial and axial forces from both directions and have zero backlash tilting moments. With the E version (ARL-E®), IBO offers improved rigidity and friction torque. The bearings of the ARL-E series are suitable for operating temperatures of -30° C and 120° C.

IBO manufactures the ARL-E® series for shaft diameters from Ø80 to Ø580 mm.

Product description

Axial-radial cylindrical roller bearings of the ARL-E®) series consist of a two-sided working axial cylindrical roller bearing and a radial cylindrical roller bearing.

The axial bearing system consists of:

  • two axial roller and cage assemblies
  • Housing washer (outer ring)
  • L-bracket (inner ring)
  • Shaft washer

the axial raceway system is backlash-free (zero clearance) when installed.

The zero-clearance radial bearing system consists of a radial roller and cage assembly.

Through-holes are provided in the outer ring, in the L-bracket and in the shaft washer for fastening in the adjacent construction.

The shaft washer and L-bracket are secured with two retaining screws for the transport.

All bearings of the ARL-E® series are delivered factory-lubricated with the grease according to the specs.

Suffix

The following standard designs are defined for the axial-radial cylindrical roller bearings in the E version (ARL-E):

Tolerances

The diameter tolerances for the ARL-E® series correspond to the tolerance class P5 and the tolerances for the running accuracy correspond to tolerance class P4 according to WN001. The following table shows the corresponding values ​​for each bore diameter:

Design of adjacent construction

The concept and design of the connecting construction for bearings of the ARL-E series can have a negative impact on the bearing properties, such as:

  • Running accuracy
  • Preload (negative clearance)
  • Frictional torque behavior

The following parameters are mandatory for the connecting construction.

The figure shows the required characteristic values for the shaft seat:
