A roller type linear guideway includes: a rail, a sliding block sleeved on the rail, and end cover units installed at two ends of the sliding block. One of the end cover units includes a first cover plate, a second cover plate, an open end cover, and an outer end cover. The first cover plate includes a plurality of penetrating holes communicating with the non-load passages, the second cover plate is installed on the first cover plate and includes holes connected to the penetrating holes, and the open end cover is installed on one end of the sliding block and includes through holes communicating with the holes. The outer end cover closes the through holes to allow circulation of multiple rolling elements. The through holes, the holes, and the penetrating holes are connected to the non-load passages, so four rows of rolling elements can be filled simultaneously.
