Linear Bearings and Slides

A linear bearing consists of a stationary base and a sliding carriage that moves along a track or rail. The carriage usually has a rolling element, such as a ball or roller, that provides low-friction movement.

A linear slide is a linear bearing designed to support heavier loads and provide greater rigidity. They typically use two parallel tracks or rails with a carriage that moves between them. The carriage may use a rolling element, such as a ball or roller, or a sliding element, such as a plastic or composite material. Linear slides are commonly used in heavy-duty applications such as manufacturing, material handling and packaging.

Linear bearings and slides are available in a variety of materials and configurations, including:

Steel: Steel linear bearings and slides are durable and can support heavy loads.
Aluminum: Aluminum linear bearings and slides are lightweight and corrosion-resistant.
Plastic: Plastic linear bearings and slides are lightweight and can be used in wet or corrosive environments.
Ceramic: Ceramic linear bearings and slides are lightweight, corrosion-resistant and can withstand high temperatures.

Proper selection, installation and maintenance of linear bearings and slides are important to ensure optimal performance and longevity of equipment. Factors to consider when selecting linear bearings and slides include load capacity, travel distance, speed and accuracy requirements.
