The ball screw is composed of a screw, a nut and a ball. Its function is to convert rotary motion into linear motion, which is a further extension and development of ball screws. The important significance of this development is to change the bearing from rolling motion to sliding motion.
If it is a ball retainer type THK guide rail slider product, even if the THK slider is removed, the steel ball will not fall off. For other models, there are two situations: with ball holding and fixing function and without ball holding function.
THK linear guide HRX type is a highly rigid THK guide using rollers as rolling elements. In addition, compared with THK’s previous roller products, the total length of the slider is extended, and the number of effective rollers is increased, thereby increasing the static load rating of the THK rail.
The purpose of preloading is to eliminate the axial backlash and reduce the elastic displacement caused by the axial force. It can also improve the rigidity of the ball screw (to avoid step loss).
The function of the ball spline is transmission, which can perform axial linear sliding and rotational movement. However, the selection of the rolling spline is a very important link.
THK linear guide intelligent combination unit adopts the structure of attracting the inside of the outer cover, under certain environmental conditions, the THK linear guide intelligent combination unit sealing plate and its surroundings may adhere to particles.
The lubricants generally used for rolling bearings do not have a detrimental effect on cage properties. However, some synthetic oils and greases with a synthetic oil base and lubricants containing EP additives, when used at high temperatures, can have a detrimental effect on polyamide cages
BSD bearing supplies the most popular sizes of deep groove ball bearings, such as SKF, NSK, FAG, NTN, etc. SKF single row deep groove ball bearings are capped with a seal or shield on one or both sides.
With the needs of market development, THK linear bearings play an increasingly important role in the market, and have an increasingly important position in the market. For the use of THK linear bearings, it is necessary to pay attention to the lubrication requirements.
The current trend in process monitoring and predictive maintenance propels the development of sensor-rich systems. Against this background, the authors investigate using bearings’ electric properties as a sensor.
With 13 per cent of bearing failure attributed to lubrication factors, bearing lubrication is a fast-evolving area of research, supported by academics and industry alike
High-speed applications create a pair of problems for your bearing’s wellbeing: more heat and friction. Without proper planning and precautions, the added heat and friction caused by high-speed use can cause churning, slippage, and early breakage
However, to achieve reliability, they must be maintained and handled correctly. This will ensure a long bearing service life, preventing many common issues that can result in bearing failure and costly downtime.
