Frequently Asked Questions:
Q1: What is the difference between a deep groove ball bearing and a self-aligning ball bearing?
A1: A deep groove ball bearing has a deep raceway design that accommodates both radial and axial loads, while a self-aligning ball bearing has a spherical outer raceway that allows for self-alignment and accommodates higher axial loads.
Q2: How do I know if the SKF 6404 is the right bearing for my application?
A2: To determine if the SKF 6404 is suitable for your application, consider factors such as the load requirements, speed, and operating conditions. Consult with SKF's application engineers for expert guidance.
Q3: How do I maintain the SKF 6404 bearing?
A3: The SKF 6404 comes pre-greased and sealed, which reduces the need for maintenance. However, regular inspections and lubrication are recommended to ensure optimal performance and extend the service life.
Q4: Can I use the SKF 6404 in high-temperature applications?
A4: The SKF 6404 is suitable for applications with moderate temperatures. However, for high-temperature applications, consider using bearings with materials and lubricants specifically designed for high-temperature operation.
Q5: What is the lifespan of the SKF 6404 bearing?
A5: The lifespan of the SKF 6404 bearing depends on factors such as load, speed, lubrication, and operating conditions. Proper maintenance and operating conditions can significantly extend the bearing's service life.
