A GRP unit is a shaft support that pairs a cast iron pillow block housing with an insert ball bearing, supplied ready to bolt down. You will find it on conveyors, fans, mixers and similar machinery where the shaft needs a simple, sturdy fixing point. The PEER line covers several series and bore variants, so the code on the housing tells you both the bearing series and the exact bore.

Reading the code is the quickest way to identify a replacement. The letters GRP mark the pillow block family; the first digits give the bearing series, and the number after the hyphen pinpoints the bore. For instance, GRP204-12 and GRP204-13 belong to series 204 but differ in bore size, while GRP205-13, GRP205-14, GRP205-15 and GRP205-16 are all series 205 with their own bore variants. The same logic applies to GRP206-17 and GRP206-18 in series 206. Matching series plus suffix is what makes two units interchangeable.

These housings suit flat mounting surfaces and beds because the pillow block shape provides two bolt holes and allows the shaft to be aligned after installation. They handle moderate radial loads and tolerate a degree of misalignment, which is why they appear in food processing, cement, tanneries and maintenance shops as well as in agricultural equipment. The insert seal keeps dust and moisture away from the bearing; in very dirty areas it pays to confirm which seal type is fitted.

Selection comes down to shaft diameter, load type and the environment. Check the seal, plan for correct lubrication and take care with alignment at mounting, since these three points influence how long the unit lasts. On equipment that vibrates, inspect bolt tightness and the bearing internal clearance as part of routine maintenance.

When you compare a PEER GRP housing with another brand, work from the series and size: if the shaft diameter and the mounting dimensions coincide, the parts can usually be swapped. The practical method is to line up the full code and the main dimensions side by side. If you only have the code from the original machine, send it and the team can point you to the equivalent.
