Round Flange Linear Bearing LMBF Series
For LMBF circular flange linear bearing, the bushing sleeve and flange of the linear bush are formed into one piece. This type can be bolted directly to a housing, making installation simple. The ball retainer is mounted inside the bushing together with the steel balls and sealed with a retaining ring from one side or both sides of the bushing.
Flange Linear Bearing LMBF Series is a low-cost production of linear motion system for unlimited travel with the cylinder axis. Since the ball bearing point contact with the shaft, so use the load is small. Minimal friction ball rotation, thereby to obtain smooth movement precision.
The nut of the standard type Linear Bushing is integrated with a flange. This enables the Linear Bushing to be directly mounted onto the housing with bolts, thus achieving easy installation.
This round flange mount linear bearing LMBF type is relatively similar to the square flange mounted type except the flange shape. Its sub-class products are also common in the appearance and functionality. LMF, LMEF, and LMBF series available in a variety of sizes are respectively suitable for machines in Asia, Europe, and the Americas.
Application
The linear bearing can be used in the CNC multi-axis lathes, printers, power tools, sports equipment, and other machinery.
