Purpose of a Flanged bush
(OP)
Can someone help understand the difference between a sleeve and flanged bush? What is the use of a flanged bush and this effect be achieved by some other means?

RE: Purpose of a Flanged bush
Of course these are colloquial terms, that have not inherent specific meaning. A sketch would aid discussion.
But for example, a flanged bushing can support axial loads while a sleeve should not.

The effective bore/bearing-length of an unmodified flanged bushing... for the same shank length and nominal small standard chamfers... is lightly longer.
As noted, the most common purpose for flat surfaces of the flange is an integral 'plain washer-bearing' to avoid superficial fretting on mating surfaces.
Also, Some flanged-bushes are installed with deliberately 'thick' flanges... which are subsequently machined simultaneously using rigid sets of milling-cutters to ensure ultra precise side-to-side positioning, face-to-face spacing and parallel surfaces.
In some cases I have see 'flat thick flanges' recessed in spot-faces [counter-bores].
Flanged bushes can also have 'countersunk-flanges'... 90, 100, 120, 130, etc countersink angles... and the top of the bush flange may be set flush-to-high with the surface.

RE: Purpose of a Flanged bush
So far as the bush manufacturer is concerned an unflanged bush is cheaper as it can be sized in a continuous die, whereas a flanged bush has to be sized either internally or in a closed ended operation. Sizing is the process of plastically deforming the outer sleeve so that that the rubber is all in compression, which is essential for durability. Some bushes are sized during installation, I don't like that.
