Design & Configuration

The 6403 is supplied as an open bearing as standard, allowing for easy re-lubrication. To suit specific environmental needs, it can be configured with a variety of closures:

⦁ Single Shield (6403-Z) / Double Shield (6403-ZZ): For basic dust protection with minimal friction.

⦁ Single Seal (6403-RS) / Double Seal (6403-2RS): For enhanced protection against dust and moisture.

"For general industrial drives, motor repairs, and agricultural equipment, the 6403 provides a reliable, high-capacity bearing solution. Specify shield or seal suffixes to match your operating environment."
