QuadBoss 69042Rs Bearing 20x37x9

Manufactured to ABEC 3 precision levels, this QuadBoss wheel bearing measures 20mm inside diameter, 37mm outside diameter, and 9mm width. This level of precision means the bearing will run smoothly and quietly, which is important for a part that spins at high speeds. The triple-lip rubber seals are designed to keep the lubricating grease contained while also preventing water and dirt from getting inside the bearing assembly. This helps to extend the life of the bearing and maintain its performance, especially in harsh conditions.

Inside, the bearing is packed with Chevron SRI 2 grease. This specific type of grease offers good protection against rust and oxidation, and it can handle a wide temperature range, from -29 degrees C up to 177 degrees C. This makes it a solid choice for a variety of climates and riding conditions, ensuring the bearing stays lubricated and protected.
