3. Working

The ball bearing reduces rotational friction and supports radial and axial loads using balls enclosed between an inner and outer raceway. The metal seal ensures contaminants do not enter the raceway, increasing bearing life and ensuring consistent operation.

4. Principle

Ball bearings operate on the principle of rolling contact, where friction is minimized by using spherical balls between two races. The rolling action significantly reduces friction compared to sliding contact, allowing for smoother and more efficient motion.

5. Assembly

Clean all components before assembly.
Align bearing with shaft or housing.
Press fit the bearing using a bearing press or sleeve.
Ensure metal seals are intact and undamaged.
Do not apply force on the metal shield during assembly.

6. Installation Process

Inspect housing and shaft for cleanliness.
Use a proper bearing installation tool.
Gently press the bearing onto the shaft.
Fit into housing ensuring correct seating.
Avoid hammering or misalignment.
Test for free rotation after installation.

10. FAQ

Q1: What is the advantage of metal-sealed bearings?
A1: Metal shields protect the bearing from contaminants while maintaining lower friction compared to rubber seals.

Q2: Can these bearings be re-lubricated?
A2: No, these are pre-lubricated and non-serviceable.

Q3: Are custom sizes available?
A3: Yes, customized diameters and tolerances are available for bulk OEM orders.

Q4: What is the typical life expectancy?
A4: Depending on usage, up to 3–5 years or 10,000+ hours.
