The swing bearing is the critical link between the upper structure and the undercarriage of the Hyundai R220LC-9S excavator, carrying the full weight of the upper frame and transmitting the swing torque during every rotation cycle. A worn bearing shows up as play in the upper structure, rough or noisy rotation and uneven load distribution that accelerates wear on the swing drive. This replacement swing bearing is machined to restore the original rotation precision and load capacity, helping you avoid the cost of replacing the whole upper structure. It is a direct, cost-effective repair solution for machines with excessive bearing play or raceway damage.
Advantages
Stable rotation performance under full load
Durable hardened raceway construction
Reliable replacement solution for the Hyundai R series
Wide coverage across R210LC-9 to R380LC-9 class machines

Frequently Asked Questions
Which Hyundai excavator models is this swing bearing compatible with?
It is designed for the Hyundai R series 9th generation, including R210LC-9, R220LC-9, R220LC-9S, R225LC-9, R250LC-9, R260LC-9, R290LC-9 and R380LC-9. Bearing outer/inner diameter and gear teeth must be verified for the target model. For other models, please contact us with your machine model and serial number.
What are the main dimensions of this swing bearing?
Outer diameter, inner diameter, overall height and gear tooth configuration depend on the machine model and specification. Please provide your machine model and, if possible, the dimensions or OEM number of the original bearing for a precise match.
What are the symptoms of a worn swing bearing?
Typical symptoms include visible play or rocking of the upper structure, rough or jerky rotation, abnormal noise when swinging, and uneven grease or metal debris around the bearing. If any of these appear, the bearing should be inspected and replaced promptly to prevent damage to the swing drive.
Can matching swing motor and reduction gearbox parts be supplied?
Yes. Swing motor, swing reduction gearbox and related seal kits for the Hyundai R series can be supplied together. Please tell us the machine model and, if available, the OEM part numbers of the components you need.
How can I confirm the bearing matches my machine?
Send us your machine model (e.g., Hyundai R220LC-9S), serial number if available, and the original bearing's outer diameter, inner diameter, height and gear teeth information. We will verify compatibility before order confirmation.
Is the bearing tested before shipment?
Each swing bearing undergoes dimensional inspection and rotation smoothness check before packing, and export-standard wooden crate packaging is used to prevent damage in transit.
