062.20.0644.500.01.1503-KD600 Series 062 Bearings with internal gear

The KD600 series is a heavy-duty standardized single-row four-point contact ball slewing bearing with integrated internal gear, specially developed for medium to heavy-load rotary machinery scenarios. Featuring robust structural rigidity, precision internal gear transmission and optimized raceway geometry, the KD600 series delivers outstanding load capacity, stable rotational accuracy and long service life, making it a reliable and high-cost-performance rotary component for engineering machinery, automated equipment and heavy-duty rotary systems.


Typical Applications:

Construction machinery such as cranes and excavators

Aerial work platforms and man lifts

Solar tracking systems

Radar and antenna positioning systems

Materials handling equipment


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)

Characteristics

✦ Internal gear on inner ring – Gear teeth cut on the inner ring for direct pinion engagement and compact drive integration.

✦ Four-point ball contact – Single-row design handles axial, radial, and tilting moment loads simultaneously.

✦ High-capacity design – Optimized internal geometry delivers high load-carrying capacity in a robust envelope.

✦ Induction-hardened raceways – Rolling surfaces hardened for wear resistance and extended service life.

✦ Double lip seals – Fitted with NBR seals on both sides to keep contaminants out and retain lubricant.

✦ Pre-drilled mounting holes – Both rings feature equispaced bolt holes for quick and secure installation.


Features

✦ Internal gear on inner ring – Gear teeth cut on the inner ring for direct pinion engagement.

✦ Crossed roller design – Cylindrical rollers arranged alternately at 90° for high rigidity.

✦ Compact axial height – Thin cross-section saves installation space.

✦ Induction-hardened raceways – Rolling surfaces hardened for wear resistance.

✦ High moment rigidity – Resists tilting moment better than ball types.

✦ Pre-drilled mounting holes – Both rings feature bolt holes for secure installation.
