3. Working

This bearing supports axial and radial loads simultaneously due to its angular contact design. The load line does not pass through the center, enabling unidirectional axial load capacity. For combined load-bearing or higher axial loads, paired installations are recommended.

4. Principle

Angular Contact Ball Bearings operate with contact angles that allow force transmission from one ring to another at an angle to the radial axis. This design enables better load distribution, higher speed capacity, and precise motion control.

5. Assembly

Clean shaft and housing thoroughly.
Slide the bearing onto the shaft using a press-fit method.
Ensure correct orientation (contact angle direction).
Secure with snap rings or locking devices.
Lubricate as required before final assembly.

6. Installation Process

Use proper mounting tools (e.g., induction heater, bearing press).
Maintain the alignment during installation.
Avoid hammering or external stress on the bearing.
Confirm clearance settings if using paired bearings.
Test rotation manually after fitting.

10. FAQs

Q1. Why use a fiber cage instead of steel or brass?
A1. Fiber cages reduce weight, improve thermal resistance, lower noise, and offer better high-speed performance.

Q2. Can these bearings be used in paired arrangements?
A2. Yes, they are ideal for duplex (DB, DF, DT) or triplex configurations for higher axial loads.

Q3. What lubrication is recommended?
A3. Lithium-based grease or synthetic oil depending on speed and temperature.

Q4. Are these bearings available with seals?
A4. Yes. Options: Open, ZZ (metal shield), or 2RS (rubber seal).
