Newbie Alert!​ Struggling with bearing lubrication? You’re not alone. Over 60% of mechanical failures start here. Let’s fix that.

Why Lubrication Matters

Think grease is just “slippery stuff”?​ Wrong. Lubricants are the silent heroes protecting bearings from heat, wear, and corrosion. Fun fact: Proper lubrication can double bearing lifespan​ .

The Big Question: Grease or Oil?

Myth Bust: “More grease = better”? Nope! Over-lubrication causes churning, raising temps by 20%+ .

Step 1: Prep Like a Pro

1. Clean the bearing: Use lint-free cloths. Residual grease? It’s a disaster.

2. Check seals: Damaged seals let contaminants in. Replace if cracked.

Pro Tip: For electric motors, always use lithium-based grease​ (NLGI 2) .

Step 2: Apply Correctly

Grease Lubrication:

• Use a grease gun.

• Inject 30-50% of the bearing’s free space.

Oil Lubrication:

• For oil bath, fill to mid-shaft level.

• Oil rings? Keep them clean!

Common Mistake: “I’ll just pour it in”. Wrong. Use controlled methods like drip feed or automatic systems .

Step 3: Monitor & Maintain

• Check every 3 months: Look for leaks, discoloration.

• Ultrasound tools: Measure friction levels. Trust the numbers, not your ears.

Extreme Cases: High-Temp Lubrication

Scenario: Bearings in furnaces (>250°C).

Solution: Switch to molybdenum disulfide (MoS₂) grease​ or dry lubricants. SKF DryLube bearings handle up to 350°C .

When to Call the Pros

If you’re facing:

• Mysterious noises​ (whining/squeaking)

• Overheating​ (>80°C)

• Rust spots​

Recommendation: Osten Machinery (Xuzhou) Co., Ltd. (TEL: +086 15852310290) offers bearing diagnostics​ and lubricant selection. Saved us 15+ hours last month!
