The vibration of linear guideway type (LGT) recirculating "linear ball bearings" driven at a constant linear velocity was studied. The measurement results of the vibration showed that the overall levels of vibratory velocity of the LGT recirculating linearballbearings change with the measurement point of the vibration, and they are affected by linear velocity and preload. We also observed the main peaks in the vibration spectra of the LGT recirculating linearballbearing itself. The main peaks were analyzed using the modal analysis, the frequency expressions for the rigid-body natural vibrations of the carriage and the finite element method. As a result, it was made clear that the main peaks are caused by the lower rolling, the yawing, the pitching, the vertical, the higher rolling, the first flexural, the second flexural and the third flexural natural vibrations of the carriage.

Our Linear Ball Bearings Come in Various Types and Sizes, Totaling at More Than 20,000 Models of Different Specifications. Through our top Quality Linear Ball Bearings, we are Determined to Best Meet Industry Needs of Supporting a Smooth Iinear Motion in Various Machines and Facilities. 


Combining adjustable preload and long service life, SKF linear ball bearings offer a flexible, easy-to-integrate solution with mal maintenance. Ideal for downsizing linear shafting movements, the robust product range is also available in stainless steel.


By revising and improving the plastic components and optimising the load plates, Schaeffler has developed a new lightweight range of linear ball bearings that offers smoother running characteristics, higher load carrying capacity and 50 per cent longer operating life. These fag bearings are targeted at machine building, automation, control, robotics and general engineering applications.


The KN ..B-PP range is the latest addition to Schaeffler's existing, well-proven KN/KNO series of linear ball bearings, which are designed to compensate for shaft misalignment in a diverse range of applications. The new units comprise a high-strength plastic cage with steel load plates, balls, shields and seals. An external steel retaining ring supports the load plates. The bearings can support high loads, while having a relatively low mass, enabling linear guidance systems to be assembled with unlimited travel.


In developing the KN ..B-PP linear ball bearing, engineers at Schaeffler took the existing KN/KNO series and completely overhauled the design, including optimising the load plates and introducing a 'tapered' lead chamfer entry zone for the balls. Due to the self-alignment function, the balls now run freely into the load zone and load distribution over the whole row of balls is now more uniform. These design improvements result in smoother running characteristics, higher acceleration capability and prevent overloading of the individual iko bearings . In addition, noise levels are reduced and operating life is increased.
