uxcell CF4 Cam Follower KR12 Needle Roller Bearing, Chrome Steel Track Runner Bearings, 12mm Roller Diameter, M4x0.7mm Male Thread Stud Type for Machine Tool Guide Rail

DescriptionDurable Material: These track roller bearings are made of bearing steel, which is high in hardness, wear-resistant, and not easy to break or deform. Their electroplated surface finish provides effective protection against rust and corrosion, extending service life.Reliable Performance: The CF/KR series cam followers feature an external thread and cylindrical rollers for high load capacity. The fully sealed design with an efficient gap seal that effectively blocks dust and debris significantly extends bearing service life in harsh conditions.Easy Installation: The stud head has a hexagonal inner hole, which can be screwed into the machine using a hex wrench. It is recommended to clean the installation area, apply lubricant to reduce friction, and ensure that the installation axis is perpendicular (90°) to the movement path to prevent misalignment.Wide Applications: These cam follower track runner bearings are suitable for applications with limited radial space. They are commonly used in machine tools, industrial robots, mechanisms within electronic component machinery, internal combustion engine systems, and similar engineering projects.SpecificationsModel: CF4/KR12Material: Bearing SteelFinish: ElectroplatedThread Size: M4 x 0.7mmRoller Outer Diameter: 12mm/0.47"Roller Length: 9mm/0.35"Total Length: 20mm/0.79"Package Content:1 x Cam Follower Roller Bearing1 x Locking Nut
