Description:
This listing is for one SKF NA2204.2RS crowned yoke type support roller.

The SKF NA2204.2RS is a sealed track roller / support roller with needle rollers. This design combines high radial load capacity with a compact construction. The thick-walled outer ring is designed to withstand high radial loads, while the crowned roller surface helps compensate for minor alignment errors or misalignment in track applications.

Yoke type track rollers are designed to be mounted on a shaft and supported by a flat or counter track, rather than being mounted inside a housing bore. The 2RS rubber seals on both sides help protect the internal rolling elements from contamination and help retain lubricant.

The cage design separates and guides the needle rollers, helping reduce friction and heat generation compared with full complement designs, while allowing higher rotational speeds.

Common applications include conveyor systems, cam mechanisms, linear guidance systems, automation equipment, material handling machinery, and industrial track roller applications.
