Industrial Ball Bearings Inside Production Lines
4
What Is a Ball Bearing and Why Is It Critical in Production Lines?
A ball bearing is a mechanical component responsible for:
Reducing friction between rotating parts
Increasing motion efficiency
Lowering energy consumption
Protecting motors, shafts, and gearboxes
Extending the lifespan of packaging and production machines
Used widely in:
Packaging factories
Food processing plants
Plastic production lines
Conveyors
Automatic wrapping machines
Even a small bearing failure can cause:
Complete line shutdown + production loss + expensive repairs
Bearing Types Used in Industrial Machinery
Type: Deep Groove Ball Bearing
Use: Motors, conveyors, transport systems
Key Advantage: High speed and economical
Type: Angular Contact Bearing
Use: Side loads and pressure applications
Key Advantage: Higher stability and precision
Type: Self-Aligning Bearing
Use: Long or misaligned shafts
Key Advantage: Compensates misalignment and vibration
Type: Thrust Bearing
Use: Vertical/axial loads
Key Advantage: Handles heavy axial pressure

Selecting Bearings by Factory Application
4
Light conveyors
Recommended Type: Deep Groove
Common Sizes: 6001–6003
Reason: High speed with low energy consumption
Automatic packaging machines
Recommended Type: Reinforced Deep Groove
Sizes: 6204–6206
Reason: Continuous operation durability
Main motors
Recommended Type: Angular Contact
Series: 7200
Reason: Higher stability and side-load capacity
Long shafts
Recommended Type: Self-Aligning
Series: 1200
Reason: Prevents misalignment vibration
Pumps and compressors
Recommended Type: Heavy Duty / 6300 Series
Reason: Withstands high pressure loads
Professional Tips for Choosing the Right Bearing Size
Never select based on diameter only — calculate load and RPM
Use sealed types (ZZ or 2RS) in dusty or wet environments
For 24/7 factories choose heavy-duty grades
Avoid mixing similar sizes to prevent vibration
Always buy genuine brands
Use high-quality bearings for high-speed packaging lines to maximize efficiency
Common Mistakes That Cause Early Bearing Failure
Poor installation or misalignment
Over-greasing or under-greasing
Using undersized bearings
Choosing the wrong type for speed
Buying low-cost commercial copies
These errors often lead to:
Production stoppage + daily financial losses + emergency repairs

How Bearings Work Inside Factory Equipment
4
Inside every modern factory, bearings are the hidden heart of motion.
They enable:
Lower friction
Higher speed
Reduced energy costs
Motor protection
Stable 24/7 operation
A wrong selection means:
Premature wear + vibration + full production shutdown + daily losses
Quick Engineering Summary
If you operate:
Packaging factories
Food processing lines
Plastic or chemical plants
Any continuous production system
Choosing the correct bearing is not just spare parts purchasing — it is a profitability decision.
Right size equals:
Stable operation
Less downtime
Longer service life
Higher productivity
Lower maintenance cost
