A12-48E12-Series 3000 Single row ball slewing ring

2100‑series external‑tooth four‑point contact ball slewing bearing belongs to single‑row four‑point contact ball slewing ring design, which is developed following mature industry standards for medium‑load rotary equipment. It is one of our mainstream standard slewing‑bearing products with stable structure and reliable running performance.


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 design handles axial, radial, and tilting moment loads simultaneously.

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

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

✦ Chrome-alloy steel balls – High-quality rolling elements with spacers to prevent sliding friction.

✦ Medium-load capacity – Designed for moderate to medium-duty rotary applications.

✦ Broad diameter range – Raceway diameters available from 13 to 57 inches.
