012.60.2240-011.012 Series external teeth slewing bearing

The 011 and 012 series are single-row four-point contact ball slewing bearings with external gear teeth. They are designed to simultaneously handle axial loads, radial loads, and tilting moments in a compact structure.


Typical Applications:

Crane turntables and aerial work platforms

Solar tracking systems and radar equipment

Construction machinery (excavators, pile drivers) 

Industrial manipulators and medical devices


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

✦ Precision Transmission – The external teeth are ground with high accuracy, minimizing backlash and making the bearing suitable for demanding positioning and slewing control applications.

✦ High Load Capacity – The raceways are induction hardened to withstand combined axial, radial, and tilting moment loads simultaneously.

✦ Integrated Compact Design – Inner ring, outer ring, rolling elements, and spacers form a single unit, saving installation space and simplifying the host structure.

✦ Low Rotational Resistance – Optimized raceway geometry and lubrication grooves ensure smooth, low-friction rotation with stable starting torque.

✦ Environmentally Resistant – Optional seals and anti-corrosion coatings provide reliable operation in dusty, humid, or temperature-varying conditions.

✦ Easy Mounting – Mounting holes on both rings allow direct bolting to adjacent structures without additional locating components.

✦ Extended Maintenance Intervals – Pre-filled with grease and equipped with relubrication ports, reducing total life-cycle maintenance costs.


Features

✦ External tooth design – Direct engagement with pinion for precise rotary motion.
✦ Single-row ball construction – Compact and lightweight.
✦ High rigidity – Resists tilting moment effectively.
✦ Ready-to-mount – Includes integral mounting holes.
✦ Low friction torque – Smooth rotation even under load.
✦ Sealed option – Protects against contaminants.
✦ Cost-efficient – Ideal for light to medium-duty applications.
