Selection Notes
- Consider 440C stainless steel when anti-rust or cleaner use is required.
- Use ZZ or RS when dust protection or sealing is important.
- Use open bearings when low resistance or lubrication maintenance is preferred.
- Confirm bore, outside diameter, width, sealing type, speed, load and mounting space before ordering.
