The KD600-060 series is a heavy-duty toothless four-point contact ball slewing bearing optimized for medium-load rotary equipment that requires stable rigidity, flexible drive configuration and long-cycle operational reliability. Adopting industrial-grade structural design and precision raceway optimization, this gearless slewing bearing removes traditional gear transmission structures and focuses entirely on pure rotary stability and universal mechanical compatibility. With rigorous material craftsmanship and tight manufacturing tolerances, the KD600-060 series delivers outstanding comprehensive performance, serving as a durable and cost-effective rotary component for engineering machinery and industrial automation 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

✦ Four-point ball contact geometry – Single-row configuration with balls contacting the raceway at four points.

✦ Toothless ring surfaces – Both inner and outer rings have plain cylindrical faces without gear teeth.

✦ Induction-hardened raceways – Rolling paths hardened for wear resistance and extended fatigue life.

✦ Sealed raceway enclosure – Equipped with NBR rubber lip seals on both sides of the rolling chamber.

✦ Alloy steel ring material – Rings manufactured from high-strength alloy steel grades.

✦ Equispaced mounting holes – Both rings drilled with a uniform pattern of bolt holes for bolted attachment.


Features

✦ Flexible drive integration – Toothless rings allow custom drive selection, including pinions, belts, or friction wheels.

✦ Simplified system design – No gear teeth means one less precision component to specify and maintain.

✦ Cost-effective solution – Eliminating gear cutting reduces manufacturing cost compared to geared versions.

✦ Easier cleaning and maintenance – Smooth ring surfaces do not trap debris or contaminants.

✦ Reduced operating noise – No gear meshing ensures quieter machine operation.

✦ Lower rotational resistance – Friction-free toothless surface contributes to smooth, low-torque rotation.
