034.60.3550 -023.024 Standard type bearing

023 and 024 series internal gear double row different-diameter ball slewing bearings consist of three seat rings. Two rows of steel balls with varied diameters are installed in upper and lower raceways. The 90° contact angle design enables the bearing to withstand combined axial loads, radial loads and heavy overturning moments simultaneously.


Applications:

Tower cranes with medium to large working radii

Mobile cranes and truck-mounted cranes

Loading and unloading machinery

Construction equipment and excavators

Rotary tables and positioning systems


High load-carrying capacity
Resistance to high and low temperatures
Noise-free operation
Strictly controlled tolerances and appropriate internal clearance
Long service life and low maintenance requirements
Prevention of unexpected downtime (avoiding bearing fracture, seizure, and safety incidents caused by such failures, with anti-tilting capability)
