E.950.20.00.B-External gear E.20.B E.25.B series

The E series is a single-row, four-point contact ball slewing bearing featuring an external gear on the outer ring. This series is part of standard product offering and is designed for light to medium-duty applications that require compact dimensions, combined load support, and straightforward integration.


Typical Applications:

Construction machinery such as cranes and excavators

Aerial work platforms and man lifts

Solar tracking systems

Materials handling equipment

Industrial turntables 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)

Characteristics

✦ Four-point ball contact – Single-row balls contact the raceway at four points, handling axial, radial, and tilting moment loads in one compact unit.

✦ External gear on outer ring – Gear teeth cut directly on the outer ring for direct pinion engagement and power transmission.

✦ Segmented raceway geometry – Optimized ball-raceway contact profile ensures smooth rotation with low friction torque.

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

✦ Double sealing – Fitted with NBR rubber 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.
