INA KWVE30B Four Row Linear Ball Bearing Carriage 42x90x99mm

Four-row Linear Ball Bearing Carriages: Four-row linear recirculating ball bearing and guideway assemblies are the most extensive and complex group within the range of monorail guidance systems. They are used where heavy loads must be moved with high running and positional accuracy as well as low friction. The guidance systems are of a full complement design, preloaded and are suitable for long, unlimited stroke lengths.

A guidance system comprises at least one carriage, one guideway, one dummy guideway, two-piece plastic closing plugs and one lubrication connector included in the delivery.

The four-row linear recirculating ball bearing and guideway assemblies are supplied with basic greasing as standard. Linear recirculating ball bearings and guideway assemblies of the design High-Speed (Only available in size 25) are supplied in X-life quality. These bearings are characterised by optimised technological characteristics, increased robustness and a longer operating life at significantly higher velocities.

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, High-speed design, able to withstand extremely high loads
