KRV26-PP-A is a stud type track roller built as a single row needle roller bearing with a particularly thick-walled outer ring and a full complement needle roller set, which increases the number of rolling elements carrying load. The unit has a solid roller stud with a fixing thread and a mounting aid for straightforward installation, and it is produced without an eccentric collar. Outside diameter is 26.0 mm, width 36.0 mm, net mass 55.924 g. Axial guidance of the outer ring is provided by plastic axial plain washers together with a contact flange and contact washer, giving defined axial positioning without extra retaining parts. Sealing is realized as a three-stage PP arrangement with plastic axial plain washers on both sides, keeping contamination out while the full complement roller set is retained. The solid stud with fixing thread allows direct mounting on a shaft-like support without a separate axle, and the closed sealing design suits applications where the roller track runs continuously against a mating surface.
