Tensor Bearings

Tensor and Oust bearings are identical. They are probably the most advanced skateboard bearings ever made. These bearings were designed with 3 dimensional loads in mind. Most skateboard bearings are designed only to withstand vertical loads. But the truth of the matter is, your bearings break because of axial loads.

The designer of the Oust/Tensor bearing spent years understanding the loads on skateboard bearings. He also used skateboarding’s best tester: Rodney Mullen. Rodney Mullen blows out bearings like no one else. That is because Rodney does tricks that no one else does, putting the strangest loads on bearings.

The process was that the designer of this phenomenal bearing would come up with a “guess” design based on everything they knew about skateboard bearing loads. He would make the bearing and have Mullen ride it. Rodney Mullen would destroy the bearing; they would analyze the damage and determine what the causes of the bearing failure. They would re-design a new bearings, make it and have Rodney skate it again. After a bunch of tries, they finally made the ultimate bearing. It was called the Oust bearings. These tests carried out by Rodney Mullen were the inspiration for the Oust/Tensor Moc 5 Street and Moc 5 Tec bearings.

The next focus was to build bearings for speed. It is important to understand at this point that street and technical skaters skate a different speeds than vert and downhill slalom skateboarders. Therefore bearing design is going to be different. In street skating you need a more robust bearing that can handle axial loads better. For vert and slalom you need a bearing that can spin fast and withstand high heats of higher rpms.

This is when the fastest bearing (or fastest skateboard bearing) was designed. Oust/Tensor set out to make the Moc 7 Speed bearings and the Moc 9 Airs. This time they used the downhill slalom racer named “Chicken” to do the testing on the new bearing design. This Oust/Tensor Moc 9 Air bearings (which is only produced under the Oust name, Tensor stops at Moc 7) broke the downhill speed record for a human on a skateboard.
