From micro motors to heavy machinery, deep groove ball bearings have become industrial standard equipment due to their high cost performance and all-round adaptability. Master the core knowledge in just 3 minutes!
1. Three irreplaceable characteristics
A master of compound loads
It can handle radial and axial loads on one shoulder, with a contact Angle of 15° to disperse stress and increase service life by 30%
2. Speed King
The precision grade (ABEC7) has a rotational speed of up to 30,000rpm and a runout of ≤0.003mm
3. Master of Space Optimization
It is 40% thinner than tapered roller bearings and is preferred for compact equipment
Examples of Scenario-based Applications
New energy vehicles: Electric drive bearings are resistant to shaft current corrosion, ensuring worry-free driving range
Smart home appliances: Silent sealed design, noise < 30dB (library-level silent)
Industrial robots: ±0.002mm high precision, zero error in repeat positioning
Iii. Golden Rules for Maintenance and Repair
Lubrication:
Lithium-based lipids (NLGI 2) are used below 80℃, and the fat replenishment cycle is 500 hours
Polyurea grease is selected for high-temperature scenarios, with a temperature resistance of 150℃
2. Installation:
Heat to 80℃ for hot loading, with an axial pressure of less than 50N
Violent knocking on the raceway is strictly prohibited!
