Linear actuators and methods for assembling the same are disclosed. A linear actuator according to the disclosure may include A bearing unit may be provided, which may be configured to support a connecting shaft connecting the drive shaft to the spindle and has a bearing block matched to the internal cross section of the housing. The bearing unit may have a preloading device for preloading a rotary bearing inserted into the bearing block, and the spindle may be screwed to the connecting shaft via a centering portion and a screw fastening portion.

Linear actuator and method for assembling an actuator

A linear roller bearing having a rolling body circulating shoe () including end-arranged attachment elements () as a lubricating device, wherein each attachment element contains a volume () for storing lubricant and transferring lubricant to a rail that guides the circulating shoe. According to the invention, the attachment element is formed from an inner housing shell (), which lies against the head piece () of the support body () of the circulating shoe, and an outer housing shell (), which faces away from the support body, which housing shells can be fastened to the head piece of the support body by a central screw ().

A linear actuator is disclosed having a housing and a plurality of components arranged in the housing. The actuator may include The at least one conducting component may be separated from the group of mechanical, non-conducting components by at least one seal in such a way that two mutually separate spaces sealed off from one another are formed within the housing.

Linear actuator

A guide carriage of a linear guide, which guide carriage has a back () and legs () bent away from the back () and disposed along a longitudinal axis of the guide carriage for engaging over a guide rail (), the two legs () are each provided with a longitudinal seal () having rod-shaped bodies () each of which has a sealing lip () on sides facing one another. The rod-shaped body () is supported on an abutment () of the leg () provided along the longitudinal axis, wherein the rod-shaped body () is retained on the guide carriage together with the two axial rod ends () of the rod-shaped body () and is spring-loaded against the abutment () by means of the inherent spring force of the rod-shaped body ().

Guide carriage of a linear guide

A seal for an opening of a bore in a component, with a threaded screw, around a core shaft of which a helical screw thread is arranged. The screw engages in the bore and the thread creates a mating thread in a wall of the bore. The diameter of the bore is larger than the diameter of the core shaft. A helical channel, which is located between the core shaft of the screw and a wall of the bore, and which is delimited by the thread, is interrupted at a minimum of one point in a liquid-tight and/or gas-tight manner.

Seal of an opening

A linear ball bearing having a guide carriage () which is guided on a guide rail () in a longitudinally displaceable manner and is mounted in rolling contact on longitudinal sides of the guide rail () via balls () which are arranged on each longitudinal side in at least two parallel ball rows () encircling in endless ball channels (), each ball () of the one ball row () together with an adjacent ball () of the other ball row () being held all round in cage pockets () of a common cage piece (), the cage piece () having exactly two cage pockets () for one ball () each from both ball rows (), each cage piece (), as viewed in the running direction of the balls (), being provided at both ends with convexly curved end surfaces () for contact with the end surfaces () of adjacent cage pieces (), which end surfaces () extend essentially up to the cage piece sides ().

Linear ball bearing

A saddle support for securing a saddle of a vehicle, typically of a bicycle, comprises an outer part ( ) that surrounds at least a portion of an inner part ( ) with formation of a gap ( ). A rolling bearing for a linear mounting of the inner part ( ) on the outer part ( ) is arranged in this gap ( ). A spring element ( ) acting in mounting direction spring-mounts the inner part ( ). The rolling bearing is constituted by a linear bearing assembly ( ) with recirculating rolling elements. The rolling elements ( ) are in rolling contact with rolling element raceways ( ), at least one of said rolling element raceways being configured on the linear bearing assembly ( ) and at least one other of said rolling element raceways being configured on the inner part ( ).
