About Linear Bearing :
Linear bearings are precision motion components engineered to enable smooth, accurate, and low-friction linear movement along a shaft or guide rail. Designed to carry loads while maintaining stability and alignment, they are widely used in industrial automation, CNC machines, robotics, and high-precision equipment. With durable construction and reliable performance, linear bearings ensure efficiency, accuracy, and long service life in demanding applications
