It is a high pressure seal and bearing unit. The metal assembly to the right with the yellow parts is the drive coupling. After Sam’s comment and looking at that part again, there are 3 distinct metal parts - the middle one with the holes is aluminium, while the outer two are the outer races of the two bearings. Two bearings are often used due to either ...

The image shows what is often known as a zerk fitting, aka a grease fitting. The ball seals the passage from the outside to the internals which require grease. A grease gun with a properly sized connector will snap onto the zerk fitting. The gun is used to pump grease under pressure to the area described in the image as "no space, grinds," likely ...

The name Rolamite was given to the concept of a flexible metal strip wrapped around rollers, to form a linear bearing. Not pictured in your image, there would be an outer casing which fixes the ends of the strip and prevents the rollers from moving perpendicularly to the length of the strip. And, if one or more of the rollers are to be attached to anything ...

The impulse causes lateral acceleration of the rod and rotation of the rod. $$ P=m\frac{dv}{dt} \quad \text{for lateral acceleration}$$ $$ P=I\frac{d\omega}{dt} \quad \text{for rotational acceleration}$$ We calculate the net acceleration for each point along the length of the rod and after multiplying that by the density of the rod we get the forces' acting ...

Combined thrust bearing and shaft seal / stuffing box. Yes, it's really called that. The nipple on top is to inject lubricant which has dual function of preventing water ingress to engine compartment. The thrust unit forward loads cannot be transferred to drive shaft / engine without: damage or serious design compromise The thrust bearing transfers these ...

You have to show two reference lines for tolerance measurements. One is the longitudinal axis of the linked parts. The other one is the line through the center of the pin as shown below. Does this answer your question?

You have to remember that you can control independently (or with a fixed gear ratio), the rotational velocity for each roll. So, in order to decrease the tension, what you do is you decrease the rolling speed progressively in the output zone. A very similar concept which is under the same restrictions, is the belt pulley system. Below it shows the tension ...

Kevin Reid answered the question, and I've accepted it-thanks, Kevin! This answer is to post a copy of relevant parts of the original article that had become rather blurry in my memory. I'll probably post other related info as I dig it up in order to catch the best selection of search keywords possible in case anyone else ever looks for sliding mechanical ...

Gimbals are the classic solution for this: https://en.wikipedia.org/wiki/Gimbal And if you don't need any roll, you can omit one of the gimbal rings, in which case a pan/tilt mechanism is sufficient (often sold for photography.) You might look for a gimballed gyroscope toy and start with that. (Flight quality gimbals are expensive.)

Perhaps a "turntable bearing" also called a "lazy susan" bearing. Something like this one: https://www.amazon.com/Square-Inch-Susan-Turntable-Bearing/dp/B00ZSQSWTM

Look for overrunning clutch or power transmission elements. You may find a lot of info in Ringspann site: Ringspann power transmission section Or here: Ringspann catalogue
