Import Excavator Slewing Bearing — Buy in Bulk from Supplier in China

This excavator slewing bearing is designed to support axial, radial, and moment loads simultaneously, functioning as a rotating interface between the upper and lower structure of an excavator. It is supplied as a complete ring with mounting holes on both inner and outer rings, allowing direct bolting to the chassis and turntable without housing or shaft. The bearing enables both oscillating and continuous rotation under heavy dynamic loads.

Slewing bearings of this type typically use high-carbon chromium steel (such as 52100 or 100Cr6) for rings and rolling elements, hardened to 58 - 62 HRC. The raceways are precision ground to tolerances of ±0.05 mm, and seals are typically rubber-lipped to exclude dirt and retain lubricant. The bearing may be supplied with internal or external gears, though the listing does not specify gear type or module. Standard lubrication points are integrated for grease injection.

This bearing is used in 20 - 50 ton excavators for swing drive applications. Buyers in construction equipment maintenance, OEM parts replacement, and heavy machinery refurbishment commonly source this component. The supplier does not state load capacity, gear ratio, or seal type. Packaging is standard for large bearings: wrapped in anti-rust paper, secured in a wooden crate. Buyers must confirm exact dimensions, gear specifications, and load ratings before ordering.

The absence of technical documentation or load data implies the need for direct confirmation of specifications before purchase.
