Kawasaki Ninja EX250/EX300 Ceramic Wheel Bearings Front/Rear 2008/2017

Description

Kawasaki Ninja 250/300 Ceramic Wheel Bearings Front/Rear  The ceramic balls in these hybrid bearings are over 60% lighter than their steel counterparts resulting in faster acceleration and reduced inertial loads. Low Friction-Less Vibration the coefficient of friction for the ceramic balls is an average of 3x’s lower than steel. When you combine this with the high tolerances for roundness you get a bearing that dramatically lowers vibration levels and produces more horsepower.

Kawasaki Ninja EX400 Ceramic Wheel Bearings Front/Rear will allow you to be going faster with less energy is appealing to almost anyone and the latest innovation to make bikes go faster is ceramic wheel bearings. Since the speed of a motorcycle is most determined by the performance of its rotating parts, investing in ceramic transmission bearings by Spears Racing is a logical choice for the serious rider. Because ceramic bearings are harder than steel bearings, they are more durable, lasting anywhere from five to 20 times longer. This also equals an almost zero risk of bearing seizure. The “Longevity of a well-built high-quality ceramic bearing, in many cases, can be up to 10 times longer than commonly used stock bearings. The ‘rule of thumb’, as we like to call it when built well, and of high-quality materials, a ceramic bearing should always be able to outlast and outperform a steel bearing.

Kawasaki Ninja 250/300 Ceramic Wheel Bearings Advantages

​First, Ceramic Wheel Bearings  are much lighter than their steel counterparts. As much as 50-75% lighter, the silicon nitride balls weight 60% less than equally-sized steel ball bearings, meaning there’s even less weight spinning inside the races. Secondly, and perhaps most impressively in our eyes, ceramics are incredibly strong. Another point in favor of ceramics is their resistant to heat. Steel balls tend to begin displaying integrity issues around 400 degree Celsius, while ceramics can easily operate at 2,000 degrees or more.

But the one attribute that ceramic bearings are most known for is their greatly reduced friction versus steel bearings made of any form of steel. How much better are they, you ask? About 1/10 of the overall friction. That means your wheels and other components can roll and roll all day.

All of this adds up to a form of bearing that not only performs better, but also lasts much, much longer. Some estimates in our research put it at five to ten times longer, although the actual useful life can depend on who you’re asking or what you’re doing with the bearings.

​All of the Spears Racing Wheel bearings are hand packed with a High end Sodium Nitrite Inhibited Grease that is insoluble  and has a decomposition Temperature of 320°C  (608 °F)
