KR19-SK-PP Roller, Track, D19, Conveyor, Gravity, Made in, CC11-BJM0266

Description:

The KR19-SK-PP Track Roller is a stud-type cam follower bearing designed for conveyor systems, linear guides, and cam-driven machinery. Featuring a 19 mm outer diameter with a thick-walled outer ring and integrated needle roller bearing, it is engineered to provide smooth rolling motion and high radial load capacity. The PP designation indicates double lip seals for protection against contaminants, making it suitable for gravity conveyors and industrial material handling equipment.

Applications:

The KR19-SK-PP Track Roller is used in gravity conveyors, conveyor guide rails, cam mechanisms, linear motion systems, packaging equipment, and automated industrial machinery. Its sealed design and stud mounting allow reliable operation in applications requiring smooth rolling guidance and long service life.
