11-502355/2-06420-External Toothed 11 Series slewing bearing

The LYMC Bearing11 series is a single-row, four-point contact ball slewing bearing featuring an external gear on the outer ring. This series belongs to LYMC’ S light to medium-duty product range and is designed for applications where compact dimensions, combined load capacity, and cost-effectiveness are key requirements.


Typical Applications:

Machine tools and robotics

Palletizers and handling equipment

Construction machinery such as cranes and excavators

Solar tracking systems

Radar and antenna 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)

Characteristics

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

✦ External gear on outer ring – Gear teeth cut directly on the outer ring for direct pinion drive.

✦ Double-sealed – Equipped with seals on both sides to keep contaminants out and retain lubricant.

✦ Compact installation – Mounting holes on both rings allow direct bolting to adjacent structures.

✦ Induction-hardened raceways – Hardened rolling surfaces deliver wear resistance and long service life.

✦ Broad size range – Available in multiple diameters and configurations for medium to heavy-duty rotary applications.
