Advantages and Characteristics:The TBI precision ball screw spline RSSY series is a combination of screw and spline. TBI ball screw is a high-precision mechanical component, and every small difference may cause mechanical damage. When selecting, it must be treated rigorously, preferably with detailed drawings. TBI spline shaft is a type of mechanical transmission that functions similarly to flat keys, half circle keys, and oblique keys, all of which transmit mechanical torque

Characteristics of TBI ball screw

1. Cost saving: TBI ball screw self-lubricating ball screw does not require lubrication of pipeline systems and equipment, oil change and waste oil treatment costs, and greatly saves oil costs. Significantly extending maintenance cycle: It can maintain an appropriate amount of lubricating oil supply for a long time, greatly extending the maintenance cycle.

2. The most suitable lubrication position: The lubrication point of the self-lubricating ball screw E2 self-lubricating ball screw is located inside the nut, and the lubrication device evenly coats the rolling spiral groove of the ball on the surface of the screw to achieve the best lubrication effect.

3. Flexible installation: TBI ball screw self-lubricating ball screw can be lubricated normally in any direction without installation direction restrictions. Clean and environmentally friendly: There is no risk of oil leakage pollution or splashing during forced lubrication. Suitable for use in environments with high cleanliness requirements and with an environmentally friendly concept.

4. Easy replacement or supplementation: The special design and construction of TBI ball screw self-lubricating ball screw allows for easy disassembly, replacement, and supplementation of the oil storage device without the need for any tools, without disassembling or reassembling the screw assembly or machine structure, saving the cost of oil change.

5. Corresponding lubricating oil can be selected: TBI ball screw self-lubricating ball screw detachable oil storage tank can be filled with appropriate lubricating oil according to the different environments in which the ball screw is used.

6. Special environmental use: Ball screws are self-lubricating. In dusty environments, harsh weather conditions, and water environments, self-lubricating products can be used in conjunction with grease to achieve good lubrication effects.

TBI Rotary Screw Spline Model Description

Application of TBI spline shaft

TBI spline shafts are widely used in industries such as aircraft, automobiles, tractors, machine tool manufacturing, agricultural machinery, and general mechanical transmission devices.

TBI ball spline shaft RSSY features: multi tooth operation, high load-bearing capacity, good centering, good guidance, shallow tooth roots, low stress concentration, minimal weakening of shaft and hub strength, easy processing, and can achieve high accuracy through grinding methods. There are two series in the standard (light series and medium series).

Advantages of rotating screw spline

Zero clearance in spline rotation direction/high positioning accuracy

The contact angle between the RSSY spline nut and the steel ball is 45 °, and it adopts a bearing DF (face-to-face combination) design. It can absorb the difference during assembly and automatically adjust the concentricity. It can also withstand large axial loads and high-precision assembly. See the figure below

DF (Face to Face Combination) Design

Low noise/high rigidity

Through high-precision grinding technology, the steel ball smoothly travels along the tangent direction inside the nut, reducing noise and friction caused by obstruction, and improving rigidity and lifespan.

Easy installation/space saving

The nut and bearing sleeve are integrally formed, and during assembly, only the screw and bearing sleeve need to be locked onto the support seat, which is very convenient. The nut and bearing sleeve are integrally formed, and the nut has a small volume and a large assembly space.

Precision specifications

The ball screw/spline is cracked according to the following specifications
