Sheary again put the Penguins ahead and Ryan McDonagh hauled the Rangers level for a third time but goals from Matt Cullen and Sidney Crosby earned the victory for Pittsburgh.
Captain Steven Stamkos scored twice as the Tampa Bay Lightning ended a three-game losing streak with a 4-0 win over the Columbus Blue Jackets.
Ben Bishop turned aside 37 shots for his fourth shutout of the season and Vladislav Namestnikov and Ondrej Palat got the other goals for the Lightning.
Michael Grabner scored the only goal and Jonathan Bernier recorded his third shutout of the season in the Toronto Maple Leafs' 1-0 win over the Detroit Red Wings at Joe Louis Arena.
Bernier made 38 saves and Grabner's seventh goal of the season 30 seconds from the end of the second period earned him the victory.
