Since 1897, one of our primary goals at the Boca Bearing Company has been to maintain the world's largest inventory of miniature bearings in all of the most popular metric and inch sizes. We also have an extensive inventory of special sizes and styles, including hybrids, three-piece thrust, phenolic and plastic-caged bearings. Currently, Boca Bearing Company has over 3,000 different sizes and well over 2 million items in stock.
Linear bearings are a type of bearing that "bear" or support the load of the carriage during its single-axis linear movement and provide a low friction sliding surface for the guide rails. In a linear guide, the carriage is the component that travels in a straight line, back and forth, along the length of the guide rail...
Linear Actuators
A linear actuator is a means for converting rotational motion into push or pull linear motion, which can be used for lifting, dropping, sliding, or tilting of machines or materials. They provide safe and clean...
Linear Slides
Linear slides, also referred to as linear guides or linear-motion bearings, are types of bearings that allow smooth and near-frictionless motion in a single axis. Machine tools, robots, actuators, sensors, and other mechanical equipment often require moving components in a straight line in any of the three-dimensional axes...
Ball Bearings
Ball bearings are types of rolling-elements bearings that carry loads, reduce friction, and position moving machine parts while facilitating motion. They reduce surface contact and friction across moving planes by...
Ball Screws
Ball screws are mechanical linear actuators that consist of a screw shaft and a nut that contain a ball that rolls between their matching helical grooves. The primary function of ball screws is to convert rotational motion to linear motion. Ball nuts are used in...
Lead Screw
A lead screw is a kind of mechanical linear actuator that converts rotational motion into linear motion. Its operation relies on the sliding of the screw shaft and the nut threads with no ball bearings between them...
