FAQ

What is the difference between an SC204 and a UC204 bearing insert?

Both the FYH SC204 and the UC204 are dimensionally interchangeable bearing inserts with a 20mm bore. The main differences are typically in internal design, cage material, and seal construction, which can vary by manufacturer. However, for most applications, they can be used as direct replacements for one another.

What is the proper tightening torque for the set screws on the SC204?

The recommended tightening torque for the M6x0.75 set screws on an SC204 bearing insert is typically between 4.0 and 5.5 Newton-meters (Nm). Always consult the manufacturer’s installation guide for precise values to ensure proper locking without damaging the shaft or bearing.

Can this SC204 bearing be re-lubricated?

The FYH SC204 is a sealed-for-life bearing and is not designed to be re-lubricated. The pre-packed grease and dual seals are intended to last the entire service life of the bearing under normal operating conditions. Attempting to re-grease it may damage the seals and lead to premature failure.
