THK has introduced the LG guide ball bushing with raceways, which offers increased load capacities and an integrated anti-twist feature.

This provides a more compact, cost-effective design, according to the company.

The four raceways using circular arc groove designs are evenly positioned around the circumference of the shaft and inside the nut.

In comparison with the conventional ball bushing product using point contact, the load capacity is increased by a factor of 2,4 to 3,8, depending on the size considered.

The resultant effect of the load capacity increases the lifetime exponentially, thus providing a much-improved performance from the same envelope size of ball bushing.

The ball raceways offer the ability to support torque and provide an anti-twist feature.

The LG guided ball bushing is initially available with shaft diameters of 4mm, 6mm and 8mm.

The short nut version, designated LG-S, has the same dimensions as the standard LM ball bushing of the LM series.

The long version nut, designated LG-L, is also available.

Compared with LT-type ball splines, the LG series is more compact, with reduced nut length and outer diameter dimensions.
