FAQ

The housing is marked F204J, but the insert is UC202 and the box says UCF202J. Is this the correct part?

This is a valid observation. The unit is sold as a UCF202J, which correctly corresponds to the UC202 insert bearing with a 15mm bore. While the housing has a casting mark of F204J (typically for a 20mm bore insert), the internal bore of the housing is machined to correctly fit the supplied UC202 insert. This is an authentic FYH unit, and the functional specifications are those of a UCF202J.

What is the proper procedure for mounting and lubricating this bearing?

First, ensure the shaft is clean and within tolerance for a 15mm bore. Slide the unit onto the shaft and bolt the flange housing securely to a flat, rigid surface. Then, tighten the two set screws on the inner ring of the bearing to 3.5 – 5.5 Nm to lock it onto the shaft. The bearing comes pre-lubricated but should be re-lubricated periodically via the grease nipple using a standard lithium-based grease.

Is this bearing unit suitable for high-speed applications?

The UCF202J is a standard-duty bearing unit designed for low to moderate speed applications. The limiting speed depends on lubrication and load conditions but is generally around 5000 RPM. For applications approaching or exceeding this speed, or for those with high loads, a different bearing series or lubrication method may be required.
