Motorcycles
The unmatched convenience of motorcycles makes them popular worldwide, but the bearings inside are what keep rides smooth and safe.
As bikes come in all shapes in sizes, the number of bearings inside vary, but a typical motorcycle contains 20–30 built-in bearings. Motorcycle bearings reduce friction in key rotating parts, including the engine, transmission, and wheels, and the engine depends on bearings to reliably transmit power to the wheels.
Motorcycle bearings must facilitate a comfortable ride with low friction, little vibration, and high durability. All these factors also influence fuel consumption and safety—top priorities for riders. NSK product development works to optimize designs always with users and the environment in mind.
Bearings also play a huge role in a motorcycle’s sensory experience. The hum of the engine, the velvety feel of the ride, the power under your fingers– bearings influence all these factors.
NSK bearings incorporate riders’ eternal desires for an exhilarating, yet comfortable and easy-to-handle ride while ensuring reliability and safety. We continue to pursue smooth and reliable bearing rotation with reduced power losses as we move to the future.
Bearings in motorcycle engines and transmissions face dirty environments where they are subjected to shock loads at high temperatures and high-speed rotation, so they must have very high rigidity and excellent dust resistance. Moreover, wheel bearings face the added challenge of exposure to water and mud.
NSK combines material advancements and the latest heat treatment technologies for exceptional durability with internal designs optimized for high rigidity and excellent sealing performance.
As some motorcycles lack mounting space for bearings, NSK’s diverse product lineup suits a variety of load and speed conditions in tight areas. We continually work to make bearings easier to handle no matter where they are used.
NSK’s ongoing research and development focuses on reducing friction, vibration, and weight with even more compact and durable bearings for motorcycles.
