There is a library for jQuery named jscrollpane http://jscrollpane.kelvinluck.com/#examples that can modify very much.
But if you only want to hide the bar, you can also push this scrollbar out of view: http://jsfiddle.net/H27BK/
<div id="content">
<div id="scrollable"> ... ... ... </div>
</div>
with CSS
#content {
position: relative;
width: 200px;
height: 150px;
border: 1px solid black;
overflow: hidden;
}
#scrollable {
height: 150px;
width: 218px; /* #content.width + 18px */
overflow-y: scroll;
}
This all based up on a bar-width of 18 pixel.
So we can do some javascript scrollbar width detection script or simply add another div that we put in front of the scrollable div.

HTML is now:
<div id="content">
<div id="scrollable">
<div id="txt"> ... ... ...
</div></div></div>
with CSS like:
#content {
position: relative;
width: 200px;
height: 150px;
border: 1px solid black;
overflow: hidden;
}
#scrollable {
height: 150px;
width: 240px; /* the bar-width can be theoretical 240px - 200px = 40px */
overflow-y: scroll;
}
#txt {
width: 200px;
}
