A roller guide for improving the movement of an elevator car on T-shaped guide rails. The roller has first and second wheels rotatably mounted on an elevator car and spring biased to rollably engage the sides of the nose portion of a T-shaped guide rail. A bumper is secured between the wheels to slidably engage the edge of the nose portion of the T-shaped guide rail and minimize lateral sway of the elevator car as it travels. The bumper also allows for the inventive roller guide to be used to replace the sliding guides of certain types of elevators without exceeding the maximum throat clearance. The roller guide, when installed, is dimensioned to meet the required safety tolerances of the elevator and allow for safe operation of the elevator safeties.
