I have used these bearings in so many different sets of wheels With excellent results. Their preformance is so predictable that you get a true picture of the wheel, without any drama from the bearing. Out of the box, they give you a stable. Smooth roll that seems to get better session after session. Oh, and quiet, too. You will enjoy many returns from this investment. Make it!
I have skated on several of the top-marketed ceramic bearings currently available. I do like the basic premise of the ceramic bearing, but how myriad vendors present the bearings runs the gamut from grabbing your dollar to giving you a real bang for your buck. The latter is BONT's market offering in the JESA 608 CERAMIC. A substantial investment that, with care and pampering, can give a remarkable return with every cycle you keep them working for you, costing you less in the life of the bearing. I have noticed that they get "Better" with every session of use. Something that gives such a positive return throughout its potentially long life is well worth a look. Consider them...
I am getting back to skating after a 41-year break. What I am most impressed with is the level of technology applied to indoor and outdoor skating, particularly in wheel components such as hubs and tires/wheels, with the spectrum of urethane recipes. The most improvement has been in the bearings; it makes your head spin. I have now found ceramic bearings, the BONT JESA CERAMIC is leading the way in quality, performance, serviceability, and longevity. ( For me). Smooth, fast, and quiet. Many others are good, but need time to break them in for their best performance, NOT the BONT CERAMICS, they run like a dream out of the box. Yes, they are a costly choice, but their longevity is the payback. You can get a set and swap them between many sets of wheels. I did, that's cost-effective. They are worth every penny of the investment you make. Spoil yourself. They Rock.
I have experimented with many other ceramic bearing brands. After using the others, the BONT JESA 608 Ceramic Bearing is a benchmark for other ceramic bearings. I have not tried them all, but I have found several more expensive. For the money, these are an excellent investment that will deliver a substantial return with a long serviceable lifespan as a dependable piece of your skating kit.
I now have several sets of Bont JESA 608 Ceramic wheel bearings. I love the bearings for the smooth and quiet roll... AND Fast!! I got tired of swapping the one set I had from wheel set to wheel set, because they are such nice bearings to roll on, so I got another set to make my life easier, and so on. Every set is as good as the one before it. They are an investment that will give you a great return. Just keep 'em clean and lubed for the best result.
After using the generally considered "Best" Swiss ceramic bearings, I was not satisfied that they were as advertised. Finding the Bont JESA Swiss Ceramic offering at the Bont online store, I ordered a set. When they arrived, I was thinking that they were not that different from the other ceramics out there. First, I did a runout test on the bearings right out of the box. Not too bad, around 35 to 40 Seconds in a Bont wheel. After cleaning them and relubing them, they were tested again with a runout going over two (2) minutes, which is impressive and wonderful. I am stocked to get them out and break them in to find out what they can REALLY do. In my opinion, they are very expensive, but well worth every penny. ** Note** If you get these, go overboard a little and make sure to clean them often and keep them lubed. You will get the lifespan out of them that they were made to give you. They ARE that much better.
Truly, this is the best bearings I’ve ever experienced. They are very fast, Smoove, and quick, improve my skating over and above my expectation, pricey, but worth every penny.
