PROBLEM TO BE SOLVED: To provide a stud type track roller bearing capable of installing a seal member and a thrust washer in a small space efficiently and being formed in a small size. SOLUTION: The stud type track roller bearing is formed with a ring-shaped step 9 having an inside diameter larger than that of a raceway surface 17 at each end 36 of an outer ring 2. A flange 8 on a shaft 1 confronts one of the steps 9, while a side plate 6 installed on the shaft 1 adjacently to the raceway surface 15 of the shaft 1 confronts the other step 9. Each step 9 is formed with a ring-shaped seal groove 18, in which a thrust washer 7 and a resilient seal member 5 in tight contact with the thrust washer 7 are inserted and fitted.
