Descroption of linear ball bearing:
Linear bearings, linear ball bearings, Rodamientos lineales, Lineer Rulmanlar are linear motion systems used for linear strokes in conjunction with cylindrical shafts. Since the bearing ball is in contact with the bearing shell, the steel ball rolls with the minimum frictional resistance. Therefore, the linear bearing has small friction and is relatively stable, and does not change with the bearing speed, and can obtain a smooth linear motion with high sensitivity and high precision. Linear bearing consumption also has its limitations. The most important thing is that the bearing impact load capacity is poor, and the bearing capacity is also poor. Secondly, the linear bearing has large vibration and noise during high-speed motion.
Structer of linear motion bearing:
>Linear ball bearing is consisted of an outer race, retainer, balls and end rings.
>The retainer is incorporated inside the outer race, and has three or more rows of elliptical ball tracks that allow unlimited ball circulation and the balls circulate very smoothly in those ball tracks.
>The retainer is held by two end rings at both ends of the outer race. One side of the paralleled straight portions of the elliptical ball track is cut off open, and the balls there are in contact with the shaft surface to circulate to and for unlimitedly in the ball track according to the rectilinear reciprocation of the shaft.
>Thus the retainer forms rolling tracks, and at the same time keeps the balls from falling out when the bearing is removed from the shaft.
Linear bearing classification:
(1) Standard type, clearance-adjustable linear bearing, open linear bearing, extended linear bearing, universal linear bearing
(2) Flange type linear bearings can be divided into: round flange type, method blue type, elliptical flange type, guide round flange type, guide method blue type, guide elliptical flange type, extended round flange type.
According to the specification system:
Divided into two series, LM and LME series. Its code name LM series is used in Asia, Southeast Asian countries, Japan, South Korea, China and so on. In terms of metric size, the tolerance of the outer diameter of the linear shaft is generally h7. The LME series is mostly used in Europe, the United States, Germany, Italy and other regions. In the inch size, there are also metric sizes, and the tolerance of the outer diameter of the linear shaft is generally g6. Two series of structural features, in addition to different sizes, different aperture tolerances, the structure is roughly the same.
1: Straight type (shape is like a cylinder, usually mounted with a circlip, for installation where the size is small)
2: Flange type (with flanges at the end or middle, can be installed with screws, flanges are generally round, square and trimmed)
3: Open type (shape is straight, there are axial slits on the outside, used for occasions requiring clearance adjustment, two types of large openings and small openings)
1: normal type (used for general performance requirements)
2: Super type (for long life and large load performance requirements)
Linear bearings are increasingly used in precision equipment such as electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tool machinery, CNC machine tools, automobiles and digital three-dimensional coordinate measuring equipment. Or in the special machinery industry.
