The mechanical lifter generally includes an inner lift member, an outer lift member, and a roller. The inner lift member is at least partly made of a metallic material. The outer lift member is at least partly made of a polymeric material and surrounds the inner lift member. The roller is rotatably coupled with respect to the inner lift member and is partly disposed within the inner lift member. The inner lift member is configured to move a first component in response to a force applied to the roller by a second component.
