Notes
- On NSK bearings: “V” = rubber seal on one side; “V V” = rubber seal on both sides; “Z” = steel shield on one side; “ZZ” = steel.
- Shield on both sides; “DU” = heavy contact seal one side; “DDU” = heavy contact seal both sides.
- “Heavy Contact” = higher drag. Normally the “V V” seal is sufficient (I have never seen “DW” on an NSK bearing).
- Ball bearing mfgrs.
- All use their own numbering system although many of them are similar to each other.
- Fafnir: “P” = rubber seal, “KD” = steel shield, etc.
- SKF: “RS” = rubber seal, “Z” = steel shield, etc.
- No suffix = no seal or shield
- Seals retain grease & exclude contaminants. Shields do not – they need an auxiliary seal to do that.
- Often ball bearings that are sealed or shielded on both sides are cheaper (because they are more common).
- You can safely pry out the seal/shield on the side where it’s not needed.
- I’ve listed mostly double sealed/shielded bearings in the chart.
- The “C3” designation on some ball bearings is a clearance designation (the clearance, or “fit”, between the balls & the outer race).
- “C3” bearings are common (probably the most common), and can be used in many applications.
- Tapered roller bearing mfgrs all use the same numbering system, although some use a “4T-” prefix.
- AVOID CHINESE, TAIWANESE & EASTERN EUROPEAN BEARINGS LIKE THE PLAGUE.
THEY ARE CHEAP BUT IN THE LONG RUN THEY ARE NOT INEXPENSIVE! - GOOD BALL & ROLLER BEARINGS ARE NOT THAT MUCH MONEY.
SPEND THE EXTRA & SAVE A LOT OF HEADACHES IN THE LONG RUN.
