Product Description
XCMG XE490D slewing bearing, heavy-duty swing circle for XCMG XE490D excavator. 50Mn alloy steel with forging and heat treatment, OEM direct replacement for mining and construction works.
Our XCMG XE490D slewing bearing is a robust XE490D swing circle and premium XCMG excavator slewing bearing. As a reliable heavy-duty swing bearing, precision XE490D turntable bearing, dedicated XCMG XE490D swing bearing and long-lasting excavator slewing ring, it acts as the core rotating component for XCMG XE490D excavators. Engineered to endure heavy axial, radial and tilting loads, this swing circle delivers smooth full-circle rotation and stable performance, ideal for heavy excavation, mining and general construction operations.
Fabricated from high-grade 50Mn alloy steel, the bearing undergoes full forging and multi-stage precision heat treatment to achieve balanced hardness and toughness. Its finely machined raceways and premium rolling elements ensure low friction, consistent rotation and excellent wear resistance. Fitted with multi-layer NBR seals, it effectively blocks dust, mud and water ingress to protect internal parts in harsh working environments. Manufactured in strict accordance with OEM specifications, it matches all mounting dimensions perfectly and supports straightforward bolt-on installation with no alterations needed. It helps cut equipment downtime, lower maintenance costs and keep your XCMG XE490D excavator running at peak efficiency.
