The EXP pillow block from SNR is a ready-to-mount unit that pairs a pillow block housing with an insert bearing, so a rotating shaft can be supported on a flat base. It suits equipment where a compact, self-aligning assembly is easier to install and service than a separate housing and bearing.
Reading the code is the quickest way to identify a unit. EXP covers the SNR pillow blocks supplied with an insert bearing; the digits that follow give the nominal shaft diameter, so EXP204 and EXP205 are standard metric sizes. Where the number carries a hyphenated suffix, the shaft is measured in inches: EXP204-12 fits a 3/4" shaft and EXP205-16 fits a 1" shaft. Send the full code when you need the exact size confirmed.
Typical installations include belt conveyors, elevators, sorting belts, fans, mixers and other process equipment, along with agricultural machinery, food plants and material handling systems. Because the housing bolts to a flat base, the shaft can be aligned with minimal work, which keeps maintenance simple and limits downtime on a production line.
When choosing a unit, look at the shaft diameter, the load it carries and the conditions around it. Self-alignment in the EXP series absorbs small mounting misalignments. Give attention to the insert seal as well: dusty or damp locations call for extra protection. Inserts are generally lubricated for life, though severe duty may call for replenishment. Set the base on a clean, flat surface and tighten the bolts evenly.
Units that share a series and shaft diameter can be swapped between manufacturers, so an EXP204 may be replaced by a same-size, same-mounting unit from another maker. If you only have another brand's number or a part you cannot identify, send it over and we will point you to the matching option. MR supplies the SNR line and can help you choose the right replacement.

Frequently asked questions
- What does the -12 or -16 suffix mean on an EXP pillow block?
- A hyphenated suffix gives the shaft size in inches: EXP204-12 is built for a 3/4" shaft and EXP205-16 for a 1" shaft. The base number, 204 or 205 for example, refers to the series and the nominal diameter in millimeters. If the size is unclear, send the full part number and we will confirm it.
- How do I know if the EXP pillow block is compatible with my equipment?
- Shaft diameter, the spacing between the base holes and the center height are the figures that determine interchangeability. With the original part number or a photo of the mounting, we can identify the compatible alternative for your equipment.
- Does the insert bearing of the EXP pillow block need maintenance?
- Most inserts are lubricated for life, but dusty, humid or high-temperature conditions may make replenishment necessary. Check the seal and clearance at intervals. If the application is demanding, ask about the variant with additional protection.
