Hello everyone,

I hope you're all well.

I am trying to figure out what the bearing set up is in the photo attached. Please could I get any advice?

As far as I can see, starting from left to right, the set up is:

- A bearing end cap (I am confused, because it has a central tightening screw. Perhaps it's an adapted bar end plug for the bearing shaft?).

- A pillow block bearing (welded to back support pad).

- Bearing lock collar (out of view, but I have confirmed this viewing other videos).

- Brass coloured bushing or sleeve? - Through hole plate welded to base frame.

- Box section end and pipe within? Box section attaches to seat pad.

- Through hole welded to base frame.

- Brass coloured bushing or sleeve.

- Bearing lock collar.

- Pillow block bearing.

- Bearing end cap.

- Obviously, there is some sort of shaft running through the whole set up.

Purpose of this set up: It joins the gym bench's back support and seat pads to allow them to adjust on the same hinge.

Rep-Fitness-AB-5000-Zero-Gap-Adjustable-

Any help would be greatly appreciated.

Hi !!

I think you are pretty right

this kind of benchs are not like machines with thousands of revs, so a bushing is not necessary. I think the shaft is directly in contact with the base frame.

the rest of items.... I agree

 

- A bearing end cap

- YES, OR SIMPLY A WIDE WASHER WITH A BOLT FASTENER

 

- A pillow block bearing  

- YES

 

- Bearing lock collar  

- I CAN NOT SEE IT

 

- Brass coloured bushing or sleeve? - Through hole plate welded to base frame.

- MAY BE NOT NECESSARY

 

- Box section end and pipe within? Box section attaches to seat pad.

- YES

 

- Through hole welded to base frame.

- YES

 

- Brass coloured bushing or sleeve.

- MAY BE

 

- Bearing lock collar.

- MAY BE

 

- Pillow block bearing.

- YES

 

- Bearing end cap.

- YES , (OR WASHER+FASTENER) YOU CAN USE SEEGER CIRCLIPS TOO

 

- Obviously, there is some sort of shaft running through the whole set up.

- YES, IN THIS KIND OF MACHINES, YOU CAN USE VERY LARGE CLEARENCES IN ORDER TO MAKE THE ASSEMBLY A LOT EASIER.

 

 

I hope I helped you 

Regards.
