A linear guide apparatus may include a guide rail, a carriage block, at least two recirculating tubes, and two end covers. The carriage block has an axial sliding channel formed at a middle portion of a bottom surface thereof, and the carriage block is slidably coupled on the guide rail through the sliding channel. Each of two sides of the sliding channel has at least a sliding groove formed between the carriage block and guide rail. Each sliding groove comprises a plurality of rolling balls installed therein so as to enable the carriage block to slide forward and backward on the guide rail. Each of the sliding grooves is cooperated with a recirculating channel axially penetrating through the carriage block. Each of the recirculating tubes comprises a plurality of spiral threads to enable the rolling balls to have lateral roll at a specific angle when passing therethrough.
