Linear Bearings Are Widely Used In Precision Machine Tools


Linear bearings are widely used in electronic equipment, tensile testing machine and digital three-dimensional coordinate measuring equipment and other fine equipment, as well as multi-axis machine tools, presses, tool grinder, active gas cutting machine, printer, card sorting machine, food packaging machine and other industrial machinery Sliding parts.

Linear bearings are a low-cost linear motion system for infinite travel with cylindrical shafts. As the bearing ball and the shaft was in point contact, Linear Bearing so the use of small load. The ball is rotated with minimal frictional resistance, resulting in a high-precision smooth movement. Linear bearings are widely used in electronic equipment, tensile testing machine and digital three-dimensional coordinate measuring equipment and other precision equipment, as well as multi-axis machine tools, presses, tool grinder, Linear Bearing automatic gas cutting machine, printer, card sorting machine, food packaging machines and other industrial machinery sliding part.

Linear bearing characteristics and basic structure

Linear bearings are linear motion systems for linear travel and cylindrical shafts. Linear bearings with small friction, and relatively stable, does not change with the bearing speed, can get high-precision smooth linear motion.

Linear bearing consumption also has its limitations, Linear Bearing the most important is the bearing impact load capacity is poor, and the carrying capacity is also poor, followed by linear bearings in high-speed movement when the vibration and noise. Linear bearings are widely used in precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery sliding parts.

1.1 standard

Standard linear bearing surface is a high-precision cylindrical surface, and linear bearing with a high degree of coaxial, can be directly installed in the bearing, Linear Bearing both ends with a ring or gland fixed, easy to install, Very wide range of applications.

1.2 open type

The open bearing outer ring has an opening corresponding to the width of a row of ball bars, which can be used in applications where the shaft has been fixed to the support bar or seat to prevent the shaft from bending. Linear Bearing The clearance of such bearings is also easy to adjust.

1.3 gap type

The gap bearing is the same size as the standard bearing, and when it is fitted with an axial groove in the housing, it can be mounted on an adjustable inner bearing housing, making it easy to adjust the clearance between the bearing and the shaft. This type of bearing can be adjusted to obtain a small radial clearance.

The principle of linear bearings

As the linear bearing structure to achieve the point of contact with the shaft, the ball and the linear optical axis of the contact operation, the formation of its low friction, low resistance and high precision operation, can also run, so linear bearings are widely used in electronic equipment, Linear Bearing Testing machines and other precision equipment, as well as multi-axis machine tools, presses, tool grinder, automatic gas cutting machine, printer, card sorting machine, food packaging machines and other industrial machinery sliding parts. The structure of a linear motion ball bearing consists of a jacket, a cage, a steel ball and a retaining ring. When the sleeve is moved in the axial direction, the ball is pushed directly on the guide shaft by means of a fixed holding on it. Linear Bearing The steel ball is in the cage and can be rolled in the cage.

Linear ball bearing is a rolling contact with the shaft, and the axis for the track, in the direction of the shaft can do unlimited linear motion of high-precision bearings. Bearing outer cylinder with a cage, steel ball, side panels, etc., in the structure is guided by the cage to make a very smooth round of the ball.

Linear bearings are a low-cost linear motion system for infinite travel with cylindrical shafts. As the bearing ball and the shaft was in point contact, Linear Bearing so the use of small load. The ball is rotated with minimal friction to achieve high-precision bumps.
