The wire rope groove had undergone mid-frequency quenching to slow down the wear rate (pulleys against steel wire rope).
Double row tapered roller bearing is fitted into the pulley hole. Every bearing has separate lubricating oil duct.
The pulleys and bearing of traveling block can be exchanged with matched crown block.
