They have micro-groove raceway surfaces with self-smoothing microscopic linear grooved raceway surfaces to improve bearing lubrication and spin. Not many cons, just the price. I’m not sure if they are worth it if your budget is tight, G2’s or Standard Reds might be a better option. Tolerance: The tolerance of longboard bearings refers to the precision in the manufacturing process, ensuring consistent dimensions and smooth operation. Bearings with tighter tolerances are generally more precise and offer improved performance. Higher tolerance bearings require more precise manufacturing techniques and quality control, which can contribute to their higher cost.

However, when you're just starting out, you wont notice much difference between entry-level bearings like the Bones Reds or Bronson G2 Bearings and more expensive ceramic bearings as you wont be maxing out the bearing performance. Instead, focus on choosing a trusted brand with a reputation for producing high-quality and durable bearings that you won't have to replace or clean too often. Great for mini ramp and bowl skating but not so much for hardcore street skaters. The only ‘Super’ perk is that they are super expensive and hardcore skates need to replace them super fast. The bearings have housing to shield the balls inside from the mud and the water that makes them abrasive. If you want your bearing to last long and perform well, you need to be able to maintain it with ease. Maintenance allows you to clean out the gunk collected by the bearing, put in fresh lube and prevent it from rusting and seizing up. It can allow you to skate your bearings for months and months and to then clean it to make it perform like new.

Zealous bearings believe and strive to give the consumer the best value on the market and offer a superior first-rate product to the customer. Know your preferred skating style– Skateboard bearings have weight and impact limitations. For example, ceramic bearings are not the best when jumping high.

A skateboard bearing will experience loads of different forces and will be forced to perform in a variety of environments and situations. All of which the ABEC rating doesn’t account for. Steel bearings are the industry standard for their durability and cost-effectiveness. Steel bearings vary in quality from brand to brand, with steel, sealing, and interior ball bearings being the most important parts. The greater a set of longboard bearings is costly, the higher its quality, as they contain better sealing, higher-quality metals, and more inner ball bearings. When you come to an abrupt stop on your longboard, you’ll feel the difference between high-quality bearings and their lower-cost counterparts. Quality bearings of this type exhibit enough speed and durability. Of course, it would be a different story if the brand or manufacturing company used substandard raw steel. 02 Ceramic bearings

These cruiser board bearings incorporated a hard polymer shield to keep the bearings well-guarded. It also serves to make the maintenance process simpler, so that you can easily clean and reapply the lubricating oil after extensive use. If you look hard enough, you would also find some cheap Chinese bearings available too. So you basically have a lot of options and you need to decide which one is right for you. These bearings performed almost as well as the custom industrial grade bearings Pete had. That said, the ceramic Zealous probably wouldn’t hold up as well in an industrial setting.
