Sheffield United completed the double over Bury to remain in the League One automatic promotion places.
Richard Cresswell beat the offside trap to latch onto Kevin McDonald's through ball to put the Blades ahead.
Ched Evans turned sharply in the area to make it two and Lee Williamson drilled Matt Lowton's cut-back into the corner of the net.
The best chance for Bury, who had not lost at home since the fell to Steve Schumacher.
VIEWS FROM THE DRESSING ROOM
Bury manager Richie Barker told BBC Radio Manchester:
"I thought we more than matched them from the 18-yard box to the 18-yard box and our football was great.
"Unfortunately, they had slightly better quality in the final third and, with their finances, it means you can attract slightly better players.
"We've sold four players in six months now so I think it proves we're doing something right."
Sheffield United boss Danny Wilson told BBC Radio Sheffield:
"It was outstanding. Sometimes you can go over the top and say things about the players but as a manager you can't ask for anything more. That's a proper team performance.
"A lot of teams, and a lot of fans, will underestimate the challenge when you come here but we certainly we didn't do that and we saw in the first half how difficult they can be."
