Crossed roller bearings internal structure was 90 ° roller arranged perpendicular cross

Crossed roller bearings internal structure was 90 ° roller arranged perpendicular cross,
Spacing between rollers fitted retainer or isolation block to prevent roll-tilt roller mill mutual observation between child, effectively preventing the increase in rotational torque. Further, one of the rollers does not occur or the latch-up phenomenon of the contact; same time as the inner and outer ring is a split structure, the gap can be adjusted even if the preload is applied, can be obtained with high accuracy rotation.
2, the operation simplifies installation
Divided into two parts of the outer or inner ring, and after loading the roller holder is fixed together, so when you install operation is very simple.
3, bear large axial and radial loads
Because the rollers are arranged vertically spaced retainer by 90 ° to each other in a V-shaped groove raceway, this design makes cross roller High speed Spindle can withstand higher radial load, axial load and moment load and all load direction.
4, substantial savings in installation space
Small, thin structure of particular cross-roller lubricating oil inner and outer rings is a minimum size is close to the limit of small size, and has high rigidity, so the most suitable for the joints of an industrial robot or a rotary portion of the rotary machining center versatile table, robot rotating part, precision rotary tables, medical equipment, measuring instruments, IC manufacturing devices.
High 5 speed capability
Reducing the length of the shaft 6 and the processing cost, result in a limited thermal expansion changes the geometry

Cross roller bearings

Cross roller bearings, because the inner or outer ring is split, and the interval after loading the roller cage, and Cross-Roller Ring secured together to prevent separation from each other, so when you install the Cross-Roller Ring Operation simple. Since the roller is staggered, so only one set of Cross-Roller Ring can withstand the loads in all directions, compared with the traditional model, rigidity increased by 3 to 4 times. Meanwhile, due to cross roller bearing inner or outer ring is constructed of two split, adjustable automotive bearing clearance, even if they are applied preload can be obtained with high precision rotary motion.

Crossed roller bearings are roller between the inner and outer wheel intervals

Crossed roller bearings are roller between the inner and outer wheel intervals intersecting at right angles to each other arranged. They can withstand the load from all directions (such as an axial thrust or momentum load, etc.). Due to the roller surface into line contact with the rail, therefore, the possibility of bearing a load and elastic deformation is small. This type of super-precision bearing are widely used in industrial automation, such as robots, machine tools and medical facilities, etc., need high rigidity, compact and high-speed still ensuring accurate of occasions.
In cross roller bearings, cylindrical roller in was due to a 90 ° V-shaped groove raceway is vertically aligned with each other through a spacer retainer, so a cross roller Wind turbine bearing can bear radial load, axial load and load torque loads in all directions and so on. Minimum size of the inner and outer rings are miniaturized, in particular close to the limit of a very thin type of compact size, and has high rigidity, it is most suitable for the joint portion or a rotating portion of the industrial robot, the rotary table of the machining center, use the rotating portion of the manipulator, precision rotary tables, medical equipment, meters, IC manufacturing equipment, etc..

take into account the best use of bearings and ball

take into account the best use of turbocharger bearings and ball screw bars on rigid balancing, high rigidity and low torque of angular contact ball bearings (contact angle of 30 °, free combination). Meanwhile, the ultra-compact support unit EK6,8 equipped with ultra-small ball screw bars for the development of the ultra-compact angular contact ball bearings. This bearing contact angle is 45 °, ball diameter is small, the number of balls and more, with a high rigidity, high-precision ultra-compact angular contact ball bearings, slewing can get a stable performance.
(2) the shape of the support unit and support unit has angle-round series, can be selected according to the application.
(3) small in size and easy installation of the support unit is considered around the mounting space, the design of a small volume. Meanwhile, adjusted pre-loaded pressure Dental bearing assembly can be directly after delivery, not only reduces the assembly work, but also improve the accuracy of the assembly

Ball screw support base is connected to the screw and motor bearings

Ball screw support base is connected to the screw and motor bearing manufacturers, construction and specialty bars for standard ball screw shaft end finished goods inventory, prepare a standardized support unit EK, EF type, the general preparation of the ball screw bars standard support unit BK, BF type. The fixed side support unit fitted with JIS5 level preload adjusting the angular contact ball bearings. Especially in EK6,8 ultra-compact formula, equipped with ultra-small angle bars for ultra-small ball screw developed by the contact angle of 45 ° contact ball bearings, to achieve high rigidity, high precision and stable rotation performance. Support side support unit using deep groove ball taper roller bearing. Support unit EK, BK type of internal load bearing right amount of lithium soap grease, sealed with a special gasket, can directly install, long-term use.
