If your Volvo excavator isn’t rotating smoothly, the problem is often the slew ring (also called the swing bearing). Slew rings are mission-critical: they support the house and enable rotation, carry heavy loads, and take side, axial and overturning forces. Replacing a worn or damaged slew ring quickly and with the correct part number prevents costly downtime and secondary damage to swing motors and gearbox components.
What is a slew ring and why it matters
A slew ring (swing bearing) is a large-diameter bearing that sits between the undercarriage and the house. It transfers loads, supports the cab and boom, and allows 360° rotation. When a slew ring fails it can cause vibration, uneven wear, and suddenly unsafe operation — so timely diagnosis and correct part selection are crucial.
Popular Volvo excavator models & common slew ring part numbers
Tip: Always confirm the machine serial number and model variant (e.g., EC210B, EC210BLC, EC210LC) before ordering — similar model names can use different part numbers.

If a row above doesn’t match your machine exactly, give us the machine’s serial number (VIN) and we’ll confirm the right OEM part number before you order.
How to diagnose a bad slew ring (quick checklist)
-
Excessive play or lateral movement between house and undercarriage.
-
Grinding or knocking when rotating.
-
Visible cracks, pitting or missing teeth on the internal/external gear (if fitted).
-
Abnormal wear on swing motor or pinion.
If you spot these, stop operation and inspect — continued use can damage the swing motor and gearbox.
Replacement & installation tips (so it’s done once, done right)
-
Confirm serial/model: small model variations can change the part number.
-
Lift & align carefully: incorrect alignment during refit causes early failure.
-
Torque the bolts to OEM specs: follow the bolt tightening sequence and torque values.
-
Check grease & seals after installation; proper lubrication extends life.
-
Replace damaged fasteners — don’t reuse stretch bolts.
(We can provide torque values and bolt counts for specific models on request.)
Why buy remanufactured vs OEM new?
-
Remanufactured / aftermarket can be cost-effective and fast, but ensure quality—re-machining, heat treatment and replacement of raceways/gear teeth are critical.
-
OEM is a direct replacement but typically costs more and can have longer lead times.
We stock both options and can advise based on machine age and duty cycle.

Short FAQs (good for schema/FAQ block)
Q: How long does a slew ring last?
A: Depends on use, lubrication, and conditions; heavy site work may reduce life — inspect regularly.
Q: Can I reuse the slew ring bolts?
A: Not recommended — many are torque-to-yield and should be replaced.
Q: Do you ship internationally?
A: Yes — we ship to the UK, USA and worldwide; large slew rings often ship LTL freight.
