Edit this section Introduction
Is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. As was carrying the ball point contact with the shaft, so the use of small loads. With minimal friction ball rotation, which can get high-precision smooth movement.

Common selection of linear bearings (20)
Line shaft bearings are used in conjunction with linear hardening. For an infinite linear motion system. Ball and hardened shaft load because it is point contact, allowing the load is small, but linear motion, the minimum friction, high precision, fast movement.
Edit this paragraph classification
(1) standard linear bearings, linear bearing clearance adjustable, open type linear bearings, extended linear bearings, linear bearings versatility
(2) flange linear bearing can be divided into: Round Flange, Flange, oval flange, round flange type-oriented, blue-type-oriented approach, oriented oval flange, round flange-type extension.
According to standard specifications [1]:
Linear bearings are divided into two series that LM and LME series of its code LM series for Asia, Southeast Asia, Japan, Korea, China and so on. To the standard metric sizes, with straight shaft with diameter tolerance is generally h7. LME Series for Europe, the United States, Germany, Italy and other regions. To inch dimensions as the standard, there are metric sizes, equipped with a linear axis diameter tolerance is generally g6. Two series of structural features, in addition to different sizes, different diameter tolerance, its structure the same.
Example 1: LM 203242 UU OP
LM said that the first series of standard linear
203 242 said aperture diameter size of the structure length
UU said that the opening double-seal structure type OP
Example 2: LME 203245 UU AJ
LME said second series of standard linear
203 245 said aperture diameter size of the structure length
UU double-seal structure that AJ said adjustable gap
By shape:
1: Straight type (shape, such as cylinders, generally with Ring Installation for the installation of smaller occasions)
2: Flange (end or middle of the mounting flange can be installed with screws, the flange is generally sub-circular, square, and cutting-edge type of three)
3: Open-type (shape, such as straight, the appearance of axial slit, gap adjustment for the needs of the occasion, and the great opening and small opening two kinds)
By performance points:
1: Normal (general performance requirements of applications)
2: Super-type (long life and high load performance requirements of the occasion)
Edit this section uses
Linear bearings are currently being more widely applied to electronics, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, equipment, robotics, machine tools, CNC machine tools, automobiles and other general or special mechanical trades . [2]
Edit this paragraph maintenance
Lubrication and friction: linear bearings into the internal corrosion oil, if using oil lubrication, the first with kerosene or organic solvent removal corrosion oil, then add the dried grease. (Recommended viscosity labeled N0.2 lithium soap grease.)
If oil lubrication, corrosion does not have to remove the oil, according to the temperature change can use the ISO viscosity grade VG15-100 lubricant. Shaft lubrication from the oil supply line to no, or from outside the hole to oil the bearing seat. As the ring will scrape oil, oil lubrication is not applicable non-porous bearings with seals.
Edit this paragraph other: linear guide bearings
Made of metal or other materials or ridge slot, affordable, fixed, mobile device or devices to guide and reduce the friction of a device.
Longitudinal grooves on the rail surface or ridge, for guidance, fixed machine parts, special equipment, instruments and so on. Guide in our daily lives is also very common in applications, such as sliding doors sliding worse, the train tracks, and so are the rails of the specific application
