Usage
A 6-degree-of-freedom (6-DOF) platform is a mechanical system or device that can move independently in six different directions or axes. These axes include three translational degrees of freedom (forward/backward, left/right, up/down) and three rotational degrees of freedom (pitch, roll, yaw).

Product Description
Linear bearings are used with quench linear drive shafts, providing a system for infinite linear motion. The ball and quenched drive shaft allow for small load capacity but offer minimal friction resistance, high precision, and fast movement. Plastic linear bearings have no special requirements for the shaft and can withstand greater loads than metal bearings. However, due to sliding friction between the bearing and the shaft, their speed is limited, and the movement resistance is higher than that of metal linear bearings. Despite this, plastic linear bearings produce less noise, especially at high speeds. Additionally, they feature a chip flute design that allows dust to be expelled automatically during operation, making them suitable for dusty environments. Some models even allow for use in liquid environments due to their internal sliding film materials.
Classification
(1) Standard type, gap adjustment type, open type, extended type, universal type
(2) Flange linear bearings include round flange type, flange type, oval flange type, guide round flange type, guide flange type, oriented oval flange type, and long round flange type.
According to standard systems:
They are divided into two series: LM and LME. The LM series is used in Asia, Southeast Asian countries, Japan, Korea, and China, with metric sizes and h7 tolerance for the linear shaft diameter. The LME series is used in Europe, the US, Germany, and Italy, with British sizes and g6 tolerance for the linear shaft diameter. The structural features of both series are similar except for size and tolerance.
By shape:
1: Straight type (cylindrical shape, usually installed with a snap spring, suitable for smaller sizes)
2: Flange type (flange installed at the end or middle, secured with screws, typically round, square, or trimmed)
3: Open type (axial incision on the straight shape, for gap adjustment, with large and small openings)
Linear bearings are widely used in electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, robots, tool machinery, CNC machine tools, automotive, and digital three-dimensional coordinate measuring equipment, as well as other precision or special machinery industries.
