(Actually roller bearings) Rolling bearings in which cylindrical rollers are used as rolling elements.
Track rollers are a variant of roller bearings that use a special form of rolling element to enable linear movement along a guide rail. In contrast to ball bearings, which use spherical rolling elements, track rollers consist of elongated rolling elements in the form of cylinders or cones. The rolling elements are usually arranged around a central axis and are held at a distance by a cage or bracket.
Track rollers are often used in applications where high loads have to be moved in a linear motion, such as cranes, load elevators or sliding gates. They are also suitable for applications where high rigidity is required and the forces must be concentrated in a specific direction.
The track rollers are usually equipped with an inner ring and an outer ring, which are used for guidance on a rail. There are usually cages between the rolling elements and the rings to ensure that the rolling elements remain evenly distributed and do not touch each other. The cages can be made of different materials such as steel, plastic or brass.
Track rollers are available in different designs and sizes, depending on the application and the load capacity and speed requirements. They can also be used in combination with other rolling bearings such as ball bearings or needle bearings to improve functionality and load capacity.
In summary, track rollers are a special type of rolling bearing suitable for applications where high loads need to be moved in a linear motion. They consist of elongated rolling elements in the form of cylinders or cones that are held in a cage to remain evenly distributed.
