The BF7028 Flat Needle Roller Bearing is a linear flat roller bearing designed to provide smooth, low-friction linear motion between two parallel surfaces. It consists of a precision steel cage and needle rollers arranged in a compact, flat configuration. Its low-profile design makes it suitable for applications requiring high load capacity, stable movement, and minimal installation space.
The bearing is designed to reduce friction and wear during reciprocating or linear movement. Its steel cage helps maintain proper roller spacing and alignment, supporting reliable operation in machine tools, industrial automation equipment, precision machinery, and linear guide systems.
