▪ Integrally cast steel construction with high rigidity and resistance against deformation under heavy load
▪ Precisely machined bore maintains proper bearing fit and prevents eccentric wear
▪ Built-in seal seat forms reliable dust-proof sealing to extend bearing service life
▪ Flange holes perfectly match frame mounting points with great interchangeability and easy installation
▪ Stress relief treatment reduces cracking risk under long-term vibration
▪ Fully compatible with bearings, retaining rings and spacers for convenient overhaul procurement

FAQ

Q: Can a slightly worn bore be polished for reuse?
A: Polishing repair is not recommended. Out-of-round bore causes persistent eccentric load and rapid bearing failure. Replacement is preferred.

Q: Can minor cracks on the flange be repaired by welding?
A: Welding repair is not recommended for load-bearing areas. Welding alters internal stress and cracks will propagate under impact, bringing transmission failure risk.

Q: Which parts should be renewed together with the bearing housing?
A: It is recommended to replace bearing and oil seal together; inspect and replace retaining rings and spacers according to condition.

Q: What symptoms indicate failed bearing housing?
A: Severe vibration of drive shaft, continuous abnormal noise, frequent seal leakage, repeated bearing burnout and unstable chain meshing.
