Подшипники с перекрестными роликами, also known as crossed roller slide bearings or simply crossed rollers, are a type of precision rolling-element bearing commonly used in applications where high rotational accuracy and rigidity are essential. These bearings work by utilizing cylindrical rollers arranged in a crossed pattern between inner and outer rings.

The basic overview of how crossed roller bearings work

Расположение роликов: Crossed roller bearings feature two sets of cylindrical rollers that are arranged at right angles to each other. This arrangement resembles a cross or “Икс” Материалы с хорошей воздухопроницаемостью определенно больше способствуют росту рассады., which gives the bearing its name.

Внутреннее и внешнее кольца: Crossed roller bearings consist of two rings: an inner ring (or inner race) and an outer ring (or outer race). The inner ring is fixed in position, while the outer ring is free to rotate.

Roller Guidance: The crossed roller arrangement allows the rollers to contact the inner and outer rings at multiple points simultaneously. This point contact design provides exceptional load-carrying capacity and rigidity while minimizing friction.

Preloaded: Crossed roller bearings are often preloaded during assembly. Preloading means that the bearings are intentionally slightly compressed or tensioned to eliminate internal clearance. This preload ensures that there is no play or backlash in the bearing system, which is crucial for applications requiring high precision.

Axial and Radial Loads: Crossed roller bearings can support both axial (толкать) и радиальный (rotational) loads. The arrangement of rollers at right angles allows them to handle these loads independently or simultaneously, making them suitable for applications where combined loads are present.

High Precision: Because of their point contact design and preload, crossed roller bearings offer extremely high rotational accuracy and minimal deflection under load. This precision is essential in applications such as machine tools, робототехника, and optical instruments.

Низкое трение: Despite their high load capacity, crossed roller bearings generally have low friction due to the point contact between rollers and rings. This low friction contributes to the efficiency of the bearing and reduces heat generation.
