Frequently Asked Questions

Q: What is the difference between SB204 and SBPP204 bearing models?

A: The SB204 refers to the bearing core only — there is no housing or seat included. The SBPP204 includes both the bearing core and a pillow block seat (housing). If you already have a housing and only need to replace the insert, choose SB204. If you need the complete assembly, choose SBPP204.

Q: What inner diameter does the SB204-12 bearing core have?

A: The SB204-12 has an inner diameter of 3/4 inch, making it the inch-size equivalent of the metric SB204 (20mm ID). The "-12" suffix indicates the 3/4 inch bore size in the standard bearing designation system.

Q: Is this SB204 bearing core compatible with existing pillow block housings?

A: Yes. The SB204 / SA204 bearing cores are designed to be compatible with standard SA/SB series pillow block housings, including SBPP and SAPP type seats. Always confirm your housing dimensions before ordering to ensure a proper fit.
