The Mast Sheave Shim helps to adjust spaces, alignment, and fitment between two surfaces of the mast sheave assembly. It is strategically placed between the mast frame and the sheave assembly to prevent metal-to-metal contact or interference and provides structural stability to the sheave. This shim is used to fine-tune the fitment of parts, compensating for slight variations in dimensions and achieving desired clearances.Attributes:• Provides corrosion resistance and can withstand exposure to harsh environments• Distributes loads evenly between mating surfaces, avoiding localized stress concentrationsApplications:The Mast Sheave Shim is used to provide support for the sheave and fill the space between the sheave and its mounting surface on the mast structure to maintain optimal clearance and alignment and to achieve the desired fit and stack.
