I Beam Trolley Bearing Type

AI Thread Summary
The discussion focuses on the differences between roller bearings and sleeve bearings used in I-beam trolleys. Roller bearings feature four wheels that roll along the bottom base of the I-beam, providing smooth movement. In contrast, sleeve bearings typically involve a different design that may not utilize wheels in the same manner. Visual aids were helpful in clarifying these distinctions for the participants. Understanding these differences is crucial for selecting the appropriate trolley type for specific applications.

I am having trouble finding the difference between and I beam Trolley with a roller bearing and a sleeve bearing?

I know that the roller bearing has 4 wheels that sit on the bottom base of the I Beam and roll back and forth but I am not sure how a sleeve bearing is different from that?

Thanks

Sounds like it's describing the bearings for the wheels on the I-beam roller itself, one type having a roller bearing and the other being a sleeve bearing.

I never got to thank you for your help, but those pictures really cleared up the difference between the two bearings.

Thank you
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
