PURPOSE: A roller for a conveyor is provided to prevent a bearing from becoming damaged since a sealing unit is additionally installed, so foreign materials from a bearing are blocked at both sides. CONSTITUTION: A roller for a conveyor comprises a roller pipe body(110), a shaft(120), a bearing(130), an end cap(140), a housing member(150), a cover(180), and a second sealing unit(190). The shaft is rotatably installed on the roller pipe body. The bearing is installed between the roller pipe body and the shaft. The end cap is installed on the inner side of the roller pipe body. The housing member is installed between the end cap and the bearing. The cover is connected to the housing member and forms a first sealing unit(180a) at one side of the bearing. The second sealing unit is installed on the shaft and is installed at the other side of the bearing.
