A sheave assembly 112 has a hub 108 with an inner opening, an insert 156 and a plurality of rolling elements 120, such as ball bearings. Around the hub a sheave defines an annular space 115 for the rolling elements to rotatably mount the sheave on the hub. The hub has a radially extending aperture (148 fig.6) between the inner opening and the annular space to receive the rolling elements whilst assembling the sheave assembly. The insert is configured to be removed and inserted radially from within the inner opening. The annular space is bounded by an outer race 116 provided by the sheave and an inner race 126. The inner race is defined by a surface provided by the hub and by a continuous surface of the insert which is shaped to fill the aperture when the insert is mounted in the aperture. The insert may be secured by a fastener 180 passing through apertures 170 and (154 and 162 fig. 6).
