Quick Linear Interchange Chart

Bearing blocks in green type are stock items for us and generally ready for immediate shipment (corresponding bearing rail is also in stock in the through hole "R" mounting type).  Other styles (blue type) are typically readily available as well, but please check with us for current status.  Blocks are stocked with a light preload (Z0) and quite often in the ZA medium preload, as well. We will cut your rail to length at no additional charge
When we refer to interchangeability of linear bearing and rail products, we refer to swapping a COMPLETE assembly of Hiwin bearing/rail for another manufacturer's products. NONE of the linear brands allow for the interchange of just a single component part (bearing or rail). In other words, you cannot put Hiwin bearings on THK rail or vice versa...as an example. You also cannot substitute bearings from one product line for those in another. For instance, Hiwin makes a medium duty EGW20 bearing, but it will not work on Hiwin's heavy duty HGR20 rail.
