# Sheaves and Block Systems

## Sheaves and Block Systems

Sheaves and block systems enable lifting loads using cables and chains. Sheave bearings operate under high loads and speeds, ensuring smooth rotation.

## Loads

- High radial loads from cable tension
- Axial loads from cable misalignment
- Vibration during lifting
- Shock loads from sudden stops

## Solutions

High-load ball bearings are used. Bearings with enhanced seals are employed. Re-greaseable bearings are recommended.
