FAQ 

Q1: What accessories are used together with the bearing cover?
A1: It works with oil seal, sealing gasket, bolt and bearing to form the complete bearing housing assembly.

Q2: What signs indicate that the bearing cover needs replacement?
A2: Flange cracking, serious deformation, bolt hole tearing, obvious oil leakage at joint surface, heavy corrosion and cavity damage.

Q3: What problems will occur if damaged bearing cover continues to be used?
A3: Lubricating oil will leak continuously. Mud and grit enter bearing chamber, accelerating bearing wear, leading to shaft jamming, abnormal noise and transmission failure.

Q4: What precautions during installation?
A4: Clean flange contact surface; check gasket and oil seal integrity; tighten bolts evenly by diagonal sequence, avoid uneven force causing warpage.

Q5: How to maintain this bearing cover in daily operation?
A5: Regularly check oil leakage and bolt tightness; keep the surrounding area clean; avoid heavy impact on the housing.

Q6: What causes bearing cover damage?
A6: Vibration fatigue, impact collision, gasket aging, long-term oil corrosion, uneven bolt tightening force.

Q7: Can cracked bearing cover be welded for reuse?
A7: Not recommended. Welding repair will change casting internal stress, cracks easily expand again under vibration, better replace new bearing cover directly.
