Can my glass shelf support my 55” inch tv?

The weight rating is for an evenly distributed load so the glass will break when you put the TV on it with the weight concentrated at one or two places.  Consider buying a wall mounting bracket for under $20.

Take a piece of finished ply wood and paint it the same color as your stand, make it about 20% longer and wider than your stand, or just long enough so the supports will help bear the weight.. This will spread the weight more evenly  across a broader surface area and not point load your glass top.  I wouldn't let the weight just sit in the middle of the glass.

II googled a bunch of glass tv stands and they were usually 12 mm glass which is about 1/2 inch so i would not risk it. as is .Add more support maybe.

It would probably hold it, especially considering that the TV's stand is probably 16-18" wide so the weight the shelf experiences would be that much closer to the shelf supports.

I don't like it, but I'm pretty conservative as far as mechanical considerations are concerned.  It'll work.  I wouldn't have it, but it'll work.

should be fine.  if you are still worried, cut a piece of plywood to exactly fit the shelf so that the plywood is over the support members and put tv atop that -- this will reduce the strain on the glass.

I would not put a TV on a glass shelf, no matter how it's rated. If for any reason you bump it or move it, the tv could fall and injure you or the TV and even TEMPERED glass can shatter into millions of little pieces. 

Absolute worst case, you can add a support under the center of the TV. In actual practice, you should be able to safely put 2 TVs of that size on the shelf as is.

Tempered glass is amazingly tough. The TV is less than half the recommended weight the shelf will take. The 127 lbs is probably the safe working load rating so it would have to take much more than that before failing. So the answer is yes.

You can use the glass shelf ...but what I would do is use some pieces of thin wood  about the side of a small book under the TV legs/stands to spread the weight distribution.

It doesn't have to be wood just something firm enough.

You still should be ok if you don't use anything ...it's just an extra precaution. 

53 < 127 if you are worried put a center support on the shelf.
