FUSHI 608 INLINE & ROLLER SKATING BEARING Bearings fit inside the wheels and allow them to spin freely. A higher rated bearing has the capacity for higher speeds, However, the best tip for going fast is to keep them clean and well-oiled . So the industry standard is a steel cage with rubber sealed. MATERIALS USED IN A BEARING Steel bearings are actually among the most popular ones you can find in the market. Many consider this material as one of the best skate bearings as it is known for being the industry standard in the field of skateboarding. Each bearing houses had 7 lubricated balls designed to distribute a load’s weight and ease tension in between the skateboard’s axle and wheels. One major advantage of steel is that it is both durable and economical. However, there are also instances when the energy triggered by heavy friction between the wheels and axle tends to heat up the metal. The result is expanding or making the bearings less effective. That’s the reason why you really have to ensure that the steel bearings stay dry, lubricated, and clean, so they will work longer and more effectively. ABEC GRADE ABEC, which stands for Annular Bearing Engineering Committee, provides a rating for skateboard bearings, which indicates the performance and speed of the product. It should be noted that the ABEC rating serves as the industry’s standard in terms of determining the precision of ball bearings. ABEC 9 – Those bearings with a rating of at least 9 are considered to be extremely fast. That said, expect them to be really ideal for downhill skating. It is a good choice for you if you are an advanced skater who really wants to move extremely fast.
