NTN 6904 LLU-2RS Chrome Steel Deep Groove Ball Bearing 20x37x9 mm

The NTN 6904 LLU-2RS is a precision deep groove ball bearing designed to deliver smooth and consistent motion. It’s built to perform reliably in applications where low friction and stable rotation are required, such as cycling hubs, small motors and mechanical assemblies.

Robust Chrome Steel Construction: Constructed from premium chrome steel, this bearing offers excellent strength and resistance to wear and fatigue. The durable material helps ensure long service life, even in environments with repeated use or sustained loads.

Sealed Protection for Longevity: This bearing features rubber seals on both sides (LLU-2RS) that keep contaminants like dust, dirt and moisture out. The sealed design helps maintain internal lubrication and reduces the need for frequent maintenance.

Efficient Low-Friction Design: Precision-matched balls and raceways minimise friction and noise during operation. This low-drag performance supports quieter, more efficient motion in rotating parts, making it suitable for precision mechanisms.

A reliable choice for applications that demand smooth, low-maintenance rotation and durable, long-lasting performance.
