In industrial automation, precision, efficiency, and smooth motion are key factors in ensuring high performance and reliability.
SFERAX linear bearings are engineered to deliver exceptional results in applications that require controlled linear movement, minimal friction, and long service life.
These components are widely used in CNC machines, robotic systems, assembly lines, and automated handling equipment, where precision and durability are critical to maintaining production quality and efficiency.
What Linear Bearings Are
A linear bearing allows a sliding component, such as a carriage or shaft, to move along a guide with minimal friction.
It ensures accurate and repeatable motion, even under heavy loads or continuous operation.
Compared to traditional sliding systems, linear bearings reduce energy loss, heat generation, and mechanical wear, extending the lifespan of machinery.
SFERAX manufactures various types of linear bearings — ball, roller, and special models — each designed to meet specific industrial needs, from small automation systems to heavy-duty machinery.
