Product Details
Advantages and Characteristics:The Taiwan TBI ball screw spline RBLY5050 has a diameter of 50mm, with a symmetrical mounting hole distance of 75mm for the screw nut and 102mm for the screw nut. The TBI ball screw self-lubricating and detachable oil storage tank can be filled with appropriate lubricating oil according to the different environments in which the ball screw is used. According to the different tooth heights of TBI ball spline shafts, the tooth profile dimensions of TBI ball spline shaft splines are specified in two series in the standard, namely the light series and the medium series.

When does TBI ball screw RBLY5050 need to be preloaded? What are the advantages and disadvantages of preloading?
When high precision is required for the machine and the upper limit of the backlash is small (when used in conjunction with linear guides, the backlash of the machine during reverse motion can be close to zero).
2. Advantages: Eliminating backlash: Eliminating backlash can make the accuracy of mechanical transmission more stable and improve the rigidity of the mechanical transmission structure.
Disadvantages: The preloading of TBI ball screw must be set within a reasonable range, otherwise it will reduce mechanical efficiency. If the preloading is too high, it will cause temperature rise problems and reduce the service life,
TBI ball screw consists of a screw, nut, steel ball, pre press plate, reverser, and dust collector. The function of TBI ball screw is to convert rotational motion into linear motion, which is a further extension and development of the Ekm screw. The significance of this development is to transform bearings from rolling motion to sliding motion.
TBI ball spline RBLY5050 shaft is widely used in industries such as aircraft, automobiles, tractors, machine tool manufacturing, agricultural machinery, and general mechanical transmission devices.
TBI spline shaft RBLY5050 features: multi tooth operation, high load-bearing capacity, good centering, good guidance, shallow tooth root, low stress concentration, minimal weakening of shaft and hub strength, easy processing, and high precision can be achieved through grinding methods. There are two series in the standard (light series and medium series).
Due to the multi tooth operation of TBI spline shaft RBLY5050, it has high load-bearing capacity, good neutrality and guidance, and its shallow tooth root can reduce stress concentration. In addition, the shaft and hub strength of TBI spline shaft are weakened less, making it easier to process and achieve higher accuracy using grinding methods. The involute spline shaft is used for connections with large loads, high centering accuracy requirements, and large dimensions. Its characteristics: The tooth profile is involute, and there is radial force on the teeth when loaded, which can play an automatic centering role.
