Shielded vsOpen bearings

Thanks Greg. That makes since to me. I am still worried about the roller bearing. There is nothing to protect it. I have had line roller bearings, more than any other bearing, go bad on me. But it is about the easiest bearing to get to and cleaning and repacking it once a season or so is really nothing to complain about.

This is a very good question and observation regarding the new reel. I'm interested in why these shielded bearings were chosen. It may be for smoother lighter cranking.

I am supposing that Penn opted for the shielded bearing in the Spinfisher V to make it easier to crank. The sealed bearings would not be necessary because of the sealed gear box. Allan Hawk actually removed the seals from the bearings of his Torque for this reason. See Torque Spinner the review.

My Sargus and Battles have been very good to me through some hard fishing. One of my favorite things about them is there sealed bearings. I always thought that sealed was a step up from shielded. So why is the Spinfisher V using shielded? I'm really only worried about the line roller bearing because that area is hit with salt water soaked line all day and there is no kind of seals to protect it. This is not a criticism it’s just a question because I am no expert and I'm sure you had a good reason.

Hub assemblies are critical for safe and reliable operation of a vehicle — and they're subject to some of the harshest punishments the road can dish out. High temperatures, extreme stresses, water and contaminants can take a toll on hub assemblies that aren't up to the challenge. That's why MOOG engineers continually introduce purpose-specific innovations that stand strong against harsh conditions — and make MOOG hub assemblies durable and reliable for years of hassle-free operation.

"Shielded/non-contact bearings have a metal plate covering the balls, cage, and races. Sealed/contact bearings have a (usually black) neoprene cover instead. Open bearings, as the name suggests, have no shields or seals and are open on the sides. The big difference between a shield and a seal is the seal is a contact seal. The seals have a lip running on the inner ring of the bearing. The shield is a gap seal. It does not touch the inner ring. Sealed bearings have much more friction compared to shielded bearings, and thus are generally rated for lower speeds than shielded bearings. If you hold a shielded and sealed bearing in your hand and spin each, then you will clearly feel the difference in friction. A shielded bearing will almost spin free and a sealed bearing will not spin free."
