Eccentric Sleeve & Crusher Parts for Cone & Gyratory Crushers

Crushers—jaw, cone, gyratory, and impact types—are the first stage of size reduction in mining and aggregate operations. Their internal gear and drive components face extreme shock loads from rock fragmentation, combined with heavy contamination from dust and moisture. Unlike mill gears that run under relatively steady loads, crusher components see violent, unpredictable force spikes with every compression cycle. Hanwei supplies replacement gears, eccentric bushings, drive shafts, and related components for all major crusher types. Our parts are designed to be dimensionally interchangeable with OEM originals, enabling direct replacement without modifying the crusher housing or lubrication system.

For cone and gyratory crusher eccentric gears, we use high-strength alloy steel with controlled surface hardening to resist the brinelling and spalling that commonly occur under eccentric loading. Our CNC machining and grinding processes maintain tight tolerances on eccentricity and gear tooth geometry—parameters that directly affect crusher stroke and product gradation. Our reverse-engineering capability is essential for crusher components. Many crusher models have been in service for decades, and original drawings are often lost. Our field measurement team can capture all critical dimensions from installed components during a scheduled shutdown, then manufacture replacements that fit and function exactly like the original.

We also produce wear-resistant components using specialized alloy castings for crusher applications where abrasion resistance is the primary concern—mantle liners, bowl liners, and jaw plates in addition to gear components. With experience supplying mines across 30+ countries, we understand the urgency of crusher downtime. Our production scheduling prioritizes emergency orders for critical crusher spares.
