Inch size Linear Bearings LMB series

    Linear bearings are linear motion systems that are produced at low cost and are used with infinite strokes in conjunction with cylindrical shafts. Since the carrier ball is in point contact with the shaft, the load used is small. The steel ball rotates with a very small frictional resistance, so that smooth motion with high precision can be obtained.

     Linear bearings are widely used in precision equipment such as electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment, as well as sliding of industrial machinery such as multi-axis machine tools, punching machines, tool grinding machines, automatic gas cutting machines, printers, card sorting machines, food packaging machines, etc. component.

    There have standard type: LMB...UU, adjustable type: LMB...UU...AJ, open type: LMB...UU...OP.

    The size are LMB3UU, LMB4UU, LMB6UU, LMB8UU, LMB10UU, LMB12UU, LMB16UU, LMB20UU, LMB24UU, LMB32UU, LMB40UU, LMB48UU, LMB60UU.

    Grease lubrication: Inject the anti-corrosion oil into the linear bearing. If it is lubricated with grease, first remove the anti-corrosion oil with kerosene or organic solvent, and add grease after air drying. It is recommended to use a lithium soap grease with a tack of N0.2.

    Oil lubrication: If lubricating with oil, it is not necessary to remove the anti-corrosion oil. According to the temperature change, the lubricating oil with ISO viscosity grade VG15-100 can be selected. The shaft lubrication can be given from the oil supply pipe or from the oil hole on the outer bearing housing. oil. Since the seal will scrape off the oil, oil lubrication is not suitable for non-porous bearings with seals.

Precautions during installation:

    When the linear bearing is installed in the bearing housing, auxiliary work should be used to avoid direct impact on the end face or the sealing ring. The bearing should be evenly introduced, and the optical axis should be inserted into the linear bearing by means of a buffer plate and gently tapped. Center the shaft and the centerline of the bearing. If the shaft is inserted obliquely, the balls may fall off or cause the cage to be deformed, and damage to the linear bearings. The applied load should be evenly distributed over the entire bearing, especially when subjected to transient loads. Two or more bearings should be used. Linear bearings are not subject to rotating loads, which can cause accidents.
