Selection Notes
- F686 has a flange on the outer ring — confirm both body dimensions (6x13x5) and flange dimensions (OD ~15mm, width ~1.1mm) before ordering.
- Flange OD and width are critical parameters; do not order by body dimensions alone.
- Use GCr15 bearing steel for standard environments; stainless steel options can be discussed for corrosion resistance.
- Choose ZZ for dust protection, 2RS for water/dust ingress protection, or open for lowest friction.
- Width may differ between open and sealed versions — specify the sealing suffix clearly.
Before Ordering
F686 is available in GCr15 or stainless steel directions with ZZ/2RS/open sealing options. Please also provide mounting dimensions, flange positioning requirements, and operating speed. For cross-reference models (RF-1360ZZ, FL686ZZ, etc.), please specify when inquiring.
FAQ
Flange OD ~15mm and width ~1.1mm are common published specifications, but minor variations may exist across manufacturers. Match with actual samples or drawings when ordering.
Stainless steel versions may be available upon request. Please state stainless steel requirements during inquiry for product matching.
