Linear bearing little common sense

Linear bearing is a low-cost production of linear motion system, for unlimited travel copper sleeve with the cylindrical axis in cooperation. Because the bearing ball and the shaft was point contact, so the use of small load.

The ball with a very small friction resistance rotation, which can obtain high-precision bimetallic bearings smooth movement. Linear bearings are widely used in electronic equipment, tensile testing machine and digital three-dimensional coordinate measuring equipment and other fine equipment, and multi-axis machine tools, presses, tool grinders, active gas cutting machines, printers, card sorting machines, food packaging machines and other industrial machinery sliding part. .

Smooth and friction. Grease smooth linear bearing internal write linear bearings into the corrosion oil, if the grease smooth, the first use of oil or organic solvent economy to eradicate corrosion oil, air-dried and then increase the smooth fat. The use of viscous label N0.2 lithium soap grease. Oil smooth If the oil smooth, do not have to eradicate the anti-corrosion oil, according to the temperature change can be selected ISO viscosity grade VG15-100 smooth oil. Shaft smooth from the oil The tube is not fed, or oil is supplied from the oil hole in the outer housing. Because the seal will scratch the oil, smooth oil does not apply to non-porous with ring bearings. Coefficient of friction Coefficient of motion friction Scale. Because the energy loss due to friction is small. When the movement speed is less than 60m / min, the temperature influence can be ignored. Frictional force can be obtained by the following equation: F = ц · P + fs F: Friction force (N) *: Seal resistance (2 ~ 5N) P: External load (N) ц: Coefficient of friction. And the bearing bore and the optical axis diameter of the cooperative use of public service. In general, the bearing can not be preloaded, but high precision, light preload can be added to the bearing, but the negative diameter of the public service should not exceed the data in the table. The bearing housing and the shaft cooperate with the bearing clearance.

Bearing box of the device.

Standard Methods for Installing Bearing Boxes with Clamps and Mounting Plates. Bearing with a set screw device will cause deformation of the bearing jacket should be to prevent.
Flange-type device flange-type linear bearings, with the cooperation of the bearing housing bore surface accuracy must be accurate.
Adjustable (small opening type) bearing and bearing box on the opening phase is straight, you can get a uniform preload in the circumferential direction.
Large opening type If used in conjunction with the appropriate bearing, the large opening bearings can also be adjusted for the gap, and even be able to lighten the preload.

When the linear bearing into the bearing seat, should use the auxiliary work to prevent the direct impact on the face or seal, should use the bearing evenly introduced, with a buffer plate, by gently tap into the optical axis into the For linear bearings, the centerline of the shaft and the bearing must be aligned. If the shaft is skewed, the ball may fall or form a cage variant, but damage to the linear bearing. The applied load should be evenly distributed over the entire bearing, especially when subjected to momentary loads, using two or more Bearings. Linear bearings do not accept rotational loads, or can lead to accidents.
