The mandrel uncoiler is one of the main machines used in the steel industry. It functions to hold or clamp the coil and uncoil the main coil into long sheet plates. Common problems encountered in the field include grease melting due to heavy loads, which results in:  

• Short regreasing intervals
• High grease consumption
• Grease often dries out, leading to insufficient lubrication
• Frequent jamming or failure to expand
• Occurrence of stick-slip in the compartment
• If left unchecked, it can affect production outcome
