An elevator system (2) comprising a hoistway (4), an elevator car (6) and a counterweight (8) arranged to move within the hoistway (4). The system (2) further includes a first counterweight guide rail and a second counterweight guide rail arranged to guide the counterweight within the hoistway (4) and a guide rail bracket (32) which connects the first and second counterweight guide rails together. An elevator machine (10) is arranged to drive a tension member (14), which couples the elevator car (6) and counterweight together (8), to move the elevator car (6) within the hoistway (4). The system (2) further includes a friction reducing element (36) arranged on the guide rail bracket (32) such that if the tension member (14) moves towards the guide rail bracket (32) during operation of the elevator system (2), the tension member (14) contacts the friction reducing element (36).
