Do you know the linear ball bushing bearings?
The linear ball bushing bearings are a series of linear motions with infinite travel that are produced at low cost and are used 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 high-precision smooth motion can be obtained.
Linear ball bushing bearings consist of balls, cages, hardened jackets and seals at both ends. Since the dimensions of the various parts of the bearing have been standardized, they can be interchanged without having to worry about replacement after grinding. The jacket is made of high carbon chrome bearing steel and is hardened and finished to provide a safe and reliable assembly of the bearing inner and bearing housing. The balls run in the circuit on the cage, and the smooth ball guides ensure very low noise even at high speeds.
Linear ball bushing bearings include: LM-UU is a double-sealed cylindrical linear ball bushing bearings; LMF-UU is a double-sealed round flange linear ball bushing bearings; LMK-UU is a double-sealing method blue linear ball bushing bearings; LMH- UU is a double-sealed H-flange linear ball bushing bearings; LM-UUOP is a double-sealed open linear ball bushing bearings; LM-UUAJ is a double-sealed gap-limited linear ball bushing bearings; LM-LUU is a double-sealed extended linear Ball bushing bearings; LMF-LUU is a double seal flange extended linear ball bushing bearings; LMK/H-LUU is a double seal method blue / H type flange extended linear ball bushing bearings.
The load capacity of the linear ball bushing bearings and the optical axis after assembly is affected by factors such as design life, optical axis hardness, and load distribution on the bearing. If a linear bearing is used above 800C, the temperature coefficient should be considered and it is not allowed to be used in an environment above 1200C. If the inside of the linear bearing is lubricated with grease, first remove the anti-corrosion oil with kerosene or organic solvent, and then add grease after air drying; if it is lubricated with oil, it is not necessary to remove the anti-corrosion oil. According to the temperature change, ISO viscosity grade VG15-100 can be selected. Lubricating oil.
These linear ball bushing bearings are widely used in computers and their peripherals, automatic recording instruments and digital three-dimensional coordinate measuring equipment and other precision equipment, as well as multi-axis machine tools, punching machines, tool grinders, automatic gas cutting machines, printers, card sorters, food packaging. Sliding parts of industrial machinery such as machines.
