linear ball bearings
LINEAR BEARINGS
NSK linear guides (also caled linear bearings or guide rails) are designed for superior linear motion. NSK has designed different series of linear bearings to meet the diverse needs of the various industries we serve. For more specific applications, NSK offers special coatings, lubricants, accuracies and custom designs. Maintenance-free operation with K1 Lubrication Units are available on most NSK linear bearings.
Linear ball bearings are special ball bearings with several recirculating ball tracks. These bearings ensure that a machine element can move in a straight line along a shaft with little friction. Schaeffler Group Industrial offers linear ball bearings in compact, light and machined ranges.
Various linear ball bearings of the light range do not have an outer ring but several raceway plates on the outside diameter of the bearing on which the balls in the linear bearing roll. The mating track for all linear ball bearings is an INA shaft made from precision machined steel.
INA linear ball bearings allow friction-free and smooth linear movement. Possible misalignments in the adjacent construction of up to +/- 40 angular minutes can be compensated.
Linear ball bearing outer ring of the structure is built in a cage, cage with multiple ball, and for the infinite loop movement. Within the two ends of the spring retainer ring fixed in the work force each ball straight track side windows with gaps. This section is to allow loading of the ball for rolling contact with the shaft. With very low friction coefficient of relative movement, the linear motion ball bearings for the machinery and equipment, automation equipment, energy-saving equipment such as the most appropriate choice of bearings.
Linear motion bearings, is being more widely applied to electronics, machinery, equipment, robots, tools, machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machine tools, automotive and other general or special machinery industry into.
Use the advantages of linear motion ball bearings:
1. As the flow can start contact with friction and dynamic friction is small, so you can save energy, easy to get a higher velocity.
2. The load increases, but not sensitive to changes in the friction coefficient, so the heavy load, the friction coefficient is extremely small, and long-term accuracy of the same, can get long-term mechanical life.
3. Linear motion bearing interchangeability and easy installation saves time and make new mechanical structure, small, amount of light of the characteristics.
4. Procedures to save the oil, to simplify lubrication and maintenance purposes.
