A roller assembly for a fishing rod roller guide includes a roller having two receiving portions each receiving a bearing. A side cover is mounted to each of two ends of the roller and includes an inner side having a lip received in a first annular groove in the end of the roller. Each lip includes a second annular groove aligned with a peripheral flange on one of the ends of the roller. A ring made of soft material is partially received in each second annular groove. A gap is formed between each ring and a peripheral flange on one of the ends of the roller. A spacing portion is formed between the inner side of each side cover and one of the ends of the roller. Grease is received in the gaps and seals a portion of each bearing aligned with an end edge of one of the receiving portions.
