Saltwater Ready

No corrosion after a week at sea. The ceramic balls seem to resist rust much better than my old set.

Smooth Cast

Great upgrade for my baitcaster. The spool spins much longer and smoother than the stock steel bearings.

Good Value

One bearing was slightly stiff initially but loosened up after a few casts. Overall good value for the price.

5 FAQ

Q: Will this fit a Stradic 2500 reel?

A: Yes, provided your specific model uses 623 size bearings. Please check your reel manual for confirmation.

Q: Is there a warranty if one arrives damaged?

A: Yes, we offer a 30-day return policy on defects. Please contact us with your order number.

Q: Can I use standard grease with these bearings?

A: Low viscosity oil is preferred for speed. Heavy grease may reduce the performance benefits of ceramic.

Q: What is the difference between hybrid and full ceramic?

A: Hybrid uses ceramic balls with steel races, offering a balance of durability and performance for most anglers.

Q: Do I need to oil them before installation?

A: They come pre-lubricated with low viscosity oil, but additional maintenance is recommended after heavy use.
