Typically, crossed roller slides are more expensive than ball slides
Specifications for crossed roller slides include linear travel, dynamic load-carrying capacity, maximum linear velocity, and physical dimensions.
Linear travel is measured in inches (in), feet (ft), millimeters (mm), or centimeters (cm).
Dynamic load carrying capacity is measured in ounces (oz), pounds (lbs), grams (g), or milligrams (mg).
Maximum linear velocity is the speed at which the positioning carriage moves. Units of measure include inches per second (in/sec), feed per second (ft/sec), millimeters per second (mm/sec), and centimeters per second (cm/sec).
Physical dimensions for crossed roller slides include base length, base width, top height, carriage length, and carriage width.
Base length is the length of the base measured parallel to the main axis of travel. Base width is the width of the base measured perpendicular to the main axis of travel.
Top height is the height of the unit from the base to the top of the carriage.
Carriage length and carriage width are, respectively, the length and width of the carriage measured parallel to the main axis of movement.
Crossed roller slides differ in terms of applications and features.
