Kentledge refers to iron weights used as permanent ship ballast, or iron or concrete weights used in load testing. This method involves the construction of a platform upon which massive weights are placed. These weights bear down on the pile putting it under load. Gauges measure resistance, movement of the pile, and other readings to determine the properties of the ground.

Bearing sealed vs shieldedchart

Bi-Directional Static Load Test is a steadfast Maintained Load Test option for both large and small diameter piles that is widely used in the market. The main difference between a top-loaded maintained load test and a Bi-Directional is the location of the jack. One of the types of bi-directional method is YJACK method.[4]

Rubber sealvsmetal sealbearing

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.

"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."

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.

Doubleshielded bearing

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.

Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower.[1][2] Static load testings are performed in order to measure a design's axial tension or axial compression. It can also be used to measure its deflected shape under lateral load.[3]
