description

This original single‑row deep groove ball bearing 6210‑2RS features bore 50 mm, outer diameter 90 mm and width 20 mm. Its inner ring, outer ring and balls are made of high‑carbon chromium bearing steel, quenched and precision ground for high rolling accuracy and low friction. Contact rubber seals on both sides are pre‑filled with long‑service grease at factory, forming a maintenance‑free sealed structure without regular re‑lubrication. Under continuous vibration and splashing material on pavers, the bearing reliably supports rotating assemblies and reduces running resistance. Aged seals, raceway pitting or ball wear will trigger abnormal noise, overheating and seizure, and further lead to chain jumping and transmission lockup. Inspection is recommended during overhaul of driven wheel assemblies and tension units, and full replacement is required once damaged.

advantage

- Original standard size for good fit with shafts and housings and easy interchange
- Double rubber contact seals provide reliable protection against dust, water, asphalt fines and mud
- Pre‑filled special grease with stable sealing structure to cut routine maintenance
- Hardened bearing steel raceway and balls offer good wear and fatigue resistance for vibrating service
- Low running friction and low temperature rise to reduce transmission noise and power loss

FAQ

Q: Can grease be refilled into this sealed 6210‑2RS bearing?
A: This is a double‑contact sealed maintenance‑free bearing and not designed for re‑lubrication. Replace it once seals fail or grease deteriorates.

Q: Can a bearing with faint running noise stay in service?
A: Continuous noise or sticking during smooth rotation indicates damaged raceway or balls. It cannot be installed, otherwise sudden seizure may happen.

Q: What interference fit is required during mounting?
A: The inner ring rotating with the shaft requires proper interference, while the outer ring adopts transition fit inside housing. Never strike the raceway directly; use a mounting sleeve.

Q: Can this bearing be interchanged between left and right feeding sides?
A: Interchange is allowed with identical model. Clean shaft journals and housing grooves during installation, and replace circlips and oil seals together.
