A universal joint contains a first joint yoke and a second joint yoke. The first joint yoke and the second joint yoke are connected by a journal cross, ends of the journal cross being mounted in the joint yokes by bearings. In order to lubricate at least one of the bearings, at least one lubricant feed-through is provided, which is provided outside of a central bore of the journal cross.

A seal ring (26) configured to be employed with a cross shaft (16) including a center section (17) and four shaft sections (18a, 18b, 18c, 18d) extending in four directions from the center section and formed with step faces (17a) where the center section widens out from base ends of the shaft sections outward in radial directions of the shaft sections, and with bearings (21) for mounting to leading end portions of the shaft sections. The seal ring is fitted over the shaft section and interposed between the bearing and the step face. The seal ring includes a seal lip (34) configured to contact the step face around the entire circumference, and an indentation (36) the seal lip enters by deforming when mounted to the cross shaft.

A universal joint includes two yokes respectively connected to two rotary members, a spider rotationally coupled to the two yokes, and a bearing disposed at a portion that couples the two yokes to the spider, the bearing rotationally supporting the spider. The spider is configured to be arranged in a space defined by inner surfaces of the two yokes and allow an outer ring of the bearing to be fixed to the spider.

A shaft-hub connection, in particular for a gearbox of a motor vehicle, comprising a shaft, at least one hub which is connected to the shaft, wherein the hub is of tubular design and a shaft end of the shaft engages on a first hub end of the hub, and a closure element is arranged on a second hub end of the hub. A cavity is formed between the closure element and the shaft end of the shaft. The closure element is designed in such a manner that gaseous medium can escape via the closure element in the event of a positive pressure in the cavity.

A drive shaft (1) includes a telescopic shaft (3) having an outer tubular shaft (9) and an inner tubular shaft (11) inserted slidable into the outer shaft (9). A lubrication system is further provided, including: a lubricant receiving chamber (39) housed in the inner shaft (11); a lubricant distribution block (41) housed in the inner shaft (11); lubricant supply ports (11.9) for supplying lubricant from the lubricant distribution block (41), through a tubular wall of the inner shaft (11), towards a gap between the inner shaft (11) and the outer shaft (9); at least a lubricant transferring duct (47.1; 47.2) from the receiving chamber (39) to the distribution block (41). wherein the supplying ports (11.9) are distributed in at least two positions offset in direction of the axis (A-A) of the telescopic shaft (3).

The present disclosure provides a stabilizing system for a medical device. The stabilizing system includes a table and a stabilizing unit. The table includes a table having a base member and an upper member. The upper member is removably mounted on top of an upper portion of the base member. The upper member includes an inverted T-shaped slot. The stabilizing unit includes a base portion and a support member. The base portion has side rails. The support member is disposed on the base portion. The support member is configured to receive and support a catheter assembly comprising a catheter and a catheter handle. The stabilizing unit is mounted to the upper member of the table by sliding the side rails into the inverted T-shaped slot.
