INA KWSE20G3V1 Six Row Linear Ball Bearing Carriage 30x63x71.4mm

Six-row Linear Ball Bearing Carriages: Six-Row Linear recirculating ball bearing and guideway assemblies are full complement, preloaded units that are used in applications with long unrestricted strokes, very high loads and very high rigidity.
A guidance system comprises at least one carriage supplied fitted with a lubrication connector, one guideway, one dummy guideway, plastic closing plugs and O rings for sealing off the upper relubrication holes.

In linear recirculating ball guidance systems, the entry zones – the area in which the rolling elements enter the saddle plate up to full load – are considered as areas determining the rating life. They ensure that the load is applied to the rolling element not abruptly but steadily, which gives a more uniform load distribution. Through optimisation of the entry zone geometry, the six-row linear recirculating ball bearing and guideway assembly has not only smaller stroke pulsation but also achieves a significant increase in the basic load ratings according to its size and series in comparison with the conventional design.

Since they have the maximum possible number of rolling elements, full complement guidance systems have extremely high load-carrying capacity and particularly high rigidity. The carriages have saddle plates made from hardened steel and the rolling element raceways are precision ground. The balls are recirculated in enclosed channels with plastic return elements. The guideways are made from hardened steel and are ground on all faces, the rolling element raceways are precision ground.
Benefits: High quality, Able to withstand extremely high loads, High rigidity
