A: Yes, supporting backup rings and assorted small auxiliary gaskets are included for complete swing‑motor shaft system maintenance.

Q: How will this sealing kit react with commonly‑used onsite lubricants?
A: HNBR rubber delivers excellent thermal aging resistance and keeps low‑swelling rate for motor gear oil and swing motor bearing grease.

Q: How should warehouse staff manage long‑term stock of unopened seal kits?
A: Store in cool dry dim storage room, avoid heavy stacking pressure, sharp nicks and long‑term humidity erosion.

Q: What practical working sign tells technicians to replace seals promptly?
A: Gradual grease seepage mixed with street sand and dust particles around brush‑drive housing indicates seal abrasion and gradual aging performance drop.
