Why Replace a Worn Cable Sheave?

Cable sheaves operate under repeated loading, rotation, and wire rope contact.

Worn or damaged sheaves can interfere with cable tracking and contribute to unnecessary wear on the hoist cable and related components.

Signs that a sheave may need replacement include:

• Excessive or uneven cable groove wear

• Cracked or damaged sheave flanges

• Binding or restricted rotation

• Excessive movement around the mounting shaft

• Worn center bore or bearing surfaces

• Abnormal cable tracking

• Premature wire rope wear

Inspect the cable, mounting shaft, retaining hardware, and adjacent hoist components whenever replacing a sheave.

How to Verify the Correct Replacement Sheave

Before ordering, compare this replacement with your existing pulley:

1. Outside Diameter: Confirm a 10-inch sheave is required.

2. Inside Diameter: Verify your mounting arrangement requires a 2½-inch center bore.

3. Wire Rope Size: Confirm your equipment uses 7/8-inch cable.

4. Cable Groove: Compare the groove profile and dimensions.

5. Overall Width: Verify clearance within the existing mounting assembly.

6. Mounting Components: Check the shaft, spacers, and retainers.

7. Part Number: Confirm Galfab MA50 or a verified equivalent.

Important: A 10-inch sheave with a 2-inch bore is not a direct substitute for this 2½-inch-bore sheave.
