Installation Quality Directly Impacts Bearing Life
As core components of mechanical transmission systems, bearing installation quality directly determines equipment operational stability and service life. Statistics indicate over 60% of bearing failures result from improper installation. With decades of bearing manufacturing and field service experience, FODA BEARING provides professional installation guidance to ensure every bearing achieves its designed performance.
Pre-Installation Preparation
| Item | Technical Requirements |
|---|---|
| Cleanliness | Dust-free, oil-free environment. Shaft journals and housing bores must be clean, burr-free, rust-free |
| Dimension Check | Verify shaft diameter and housing bore diameter meet drawing tolerances |
| Bearing Inspection | Confirm FODA bearing type, no rust, no damage, intact packaging |
| Tool Preparation | Press, induction heater, torque wrench, feeler gauge, lubricant, etc. |
FODA Recommended Installation Methods
Select the most appropriate method based on bearing size, fit type, and site conditions:
① Mechanical Press Fit
Suitable for small to medium bearings with moderate interference.
② Heat Fit
Suitable for medium to large bearings, using thermal expansion for damage-free installation.
③ Oil Injection Method
Suitable for large and extra-large FODA bearings; mating surfaces require dedicated oil grooves and holes.
Clearance Adjustment (FODA Adjustable Clearance Bearings)
For FODA adjustable clearance bearings (tapered roller bearings, angular contact ball bearings, etc.), adjust after installation:
| Condition | Consequence | FODA Adjustment Method |
|---|---|---|
| Excessive clearance | Vibration, noise, uneven load distribution | Tighten nut to FODA specified torque, check axial displacement |
| Insufficient clearance | Overheating, poor lubrication, seizure | Measure with feeler gauge or dial indicator, ensure meets FODA design specs |
❌ No hammering
❌ No heating over 120°C
❌ No running without oil
❌ No skipping inspection
