Product Description
Linear bearings are used with quench linear drive shafts. This system enables infinite linear motion. The load ball and quenching drive shaft have a point contact, which allows for small loads but offers minimal friction resistance, high precision, and fast movement. Plastic linear bearings do not require special requirements for the shaft; they can withstand greater loads than metal bearings. However, since the movement between the bearing and the shaft is sliding friction, the speed of plastic linear bearings is limited. Their movement resistance is higher than that of metal linear bearings, but their noise level is lower, especially at high speeds. Plastic linear bearings feature an internal chip flute design, allowing them to handle large amounts of dust. Dust is automatically expelled from the bearing body's friction surface during movement. These bearings can also be cleaned, and special materials allow for long-term operation in liquid environments.
Classification
(1) Standard type, gap adjustment type, open type, extended linear bearing, universal linear bearing
(2) Flange linear bearings can be divided into: round flange type, flange type, oval flange type, guide round flange type, guide flange type, oriented oval flange type, and extended round flange type.
According to standard systems:
It is divided into two series, namely LM and LME series. The LM series is used in Asia, Southeast Asian countries, Japan, Korea, and China. It uses metric sizes as the standard, with linear shaft diameter tolerance generally h7. The LME series is used in Europe, the United States, Germany, Italy, and other regions. It uses British sizes as the standard, with metric sizes available and linear shaft diameter tolerance generally g6. Apart from different sizes and aperture tolerances, the structural features of the two series are roughly similar.
By shape:
1: Straight type (cylindrical in shape, usually with a snap spring installation, suitable for smaller size installations)
2: Flange type (flange installed at the end or middle, can be fixed with screws, flanges are generally round, square, or trimmed)
3: Open type (cylindrical shape with an axial cut, suitable for gap adjustment occasions, with large and small openings)
Linear bearings are widely used in electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machine tools, robots, tool machinery, CNC machine tools, automotive, and digital three-dimensional coordinate measuring equipment, as well as other precision equipment or special machinery industries.
