Narrow Arm Liner 17-301-089-001 protects the narrow arm of the crusher. It resists wear and impact from materials during operation. It prevents structural damage to the crusher’s arm components. Pinion Shaft Arm Liner 17-301-088-801 shields the pinion shaft arm. It reduces friction and wear on the shaft and surrounding parts. The two liners work together to protect key crusher components. They extend the service life of the entire Superior MKII 6089 Crusher.
Both arm liners are made with advanced CNC machining. They comply with strict OEM standards for Superior MKII 6089 Crusher. Professional QC teams monitor every production step. Dimensional tolerance is controlled within ±0.3mm for perfect fit. No on-site welding or cutting is needed for installation. Pre-drilled mounting holes enable quick and easy replacement. This saves maintenance time and labor costs for enterprises. It also minimizes equipment downtime.
Every arm liner undergoes multi-step pre-shipment testing. Tests include hardness measurement, dimensional inspection and wear resistance trials. Only 100% qualified products leave the factory. The parts are packed in high-strength wooden cases with shock padding. This prevents damage during international transportation. Choosing these parts extends the life of your Superior MKII 6089 Crusher. It reduces part replacement frequency and long-term operational costs. It is the ideal choice for routine maintenance and emergency replacement.
