We use the standard adapter sleeve for CROSSLOC™ and this is why our unitized SAF units are 100% compatible with standard SAF plummer block units. Our competitors use a one size smaller insert for their unitized SAF plummer blocks. Their adapter mount inserts are compatible with setscrew locking inserts. The standard 22200K inserts used in the SAF plummer block are one size bigger than straight bore inserts to accommodate the adapter. Since the insert being used is smaller, the load rating of their units is less than the traditional SAF plummer block.
