Precision bearings (such as deep groove ball bearings, cylindrical roller bearings, and machine tool spindle bearings) face the following cleaning challenges in their working environment
| Challenge | Impact |
|---|---|
| Roller path gap is only 0.02-0.05mm | Prone to dirt accumulation, difficult to clean thoroughly |
| Surface roughness Ra ≤ 0.05μm | Extremely delicate, susceptible to cleaning damage |
| Complex cage structure | Numerous "dead corners" for dirt accumulation |
| Residual grinding particles < 25μm | Difficult to remove, act as abrasives during operation |
Incomplete cleaning leads to:
Accelerated wear: Residual oil destroys grease stability, metal chips form "grinding agents," shortening bearing life by 30%-50%
Quality risks: Exceeding ISO 16232-10 cleanliness standards (residual oil ≤ 5mg/m²) causes equipment vibration values to exceed limits (≥0.15mm/s)
Through the synergistic effect of "temperature assistance + cavitation enhancement," it achieves efficient, thorough, and low-damage cleaning.
Core Technical Parameters:
| Parameter | Setting | Function |
|---|---|---|
| Frequency | 28-40 kHz (standard) / 80-120 kHz (precision) | 28kHz for strong cavitation, suitable for removing metal chips; high frequency for delicate surfaces |
| Temperature | 40-60°C (PID control ±2°C) | Oil viscosity decreases by 60%-70%, dissolution rate increases 3-fold |
| Power | 50%-100% adjustable | Reduce to 60% for thin-walled bearings (thickness ≤ 5mm) |
| Time | 5-15 minutes | ISO 4406 standard recommends 8-10 minutes |
| Cleaning Agent | Alkaline degreaser (5-8% NaOH + 3-5% Na₂CO₃) | Effectively removes mineral oil and emulsified cutting fluid |
| Bearing Type | Frequency Combination | Temperature | Time | Cleaning Agent Type |
|---|---|---|---|---|
| Deep groove ball bearing | 40+80 kHz | 45-50°C | 6-8 min | Alkaline water-based |
| Cylindrical roller bearing | 28+120 kHz | 50-55°C | 8-10 min | Composite solvent |
| Angular contact ball bearing | 40+80+120 kHz | 48-52°C | 10-12 min | Special formula |
| Thrust bearing | 28+40 kHz | 42-45°C | 5-7 min | Emulsion type |
For ultra-precision bearings and micro-bearings, megasonic cleaning (frequency up to MHz level) is recommended:
Extremely low cavitation erosion
Safer for surfaces sensitive to damage
Suitable for aerospace and high-end machinery bearings
