Hubless sheave

A hubless sheave comprising:

• a mounting bracket;
• a support arm detachably coupled to the mounting bracket and configured to attach the hubless sheave to a support;
• and
• a line support wheel configured to support a line, the line support wheel comprising:
• an outer race having a groove along an outer circumferential surface of the outer race, the groove being configured to receive the line, the outer race defining a first bearing surface along an inner circumference of the outer race;
• a hubless inner race coupled to the mounting bracket, the hubless inner race comprising:
• a first inner race disposed on a first side of the outer race;
• and
• a second inner race disposed on a second side of the outer race, the second inner race being removably coupled to the first inner race to define a second bearing surface along an outer circumference of the hubless inner race;
• and
• a plurality of bearings disposed between the first bearing surface defined by the outer race and the second bearing surface defined by the hubless inner race, the plurality of bearings configured to enable the outer race to rotate freely about the hubless inner race.
