Overview
The seal ring (dust seal ring) is a critical sealing component installed at the interface between the bowl assembly and the main shaft of a Symons cone crusher. It forms a labyrinth-style dust seal that prevents abrasive rock dust and fine debris from entering the crusher's internal lubrication system and contaminating the bearings and gears.
Our seal rings are cast from HT250 or HT300 cast iron , with the sealing surfaces and mounting faces CNC-machined to tight tolerances. The labyrinth profile creates a tortuous path that effectively blocks dust ingress while allowing for the crusher's gyratory motion.
Quality & Application
Each seal ring passes full dimension inspection on inner diameter, outer diameter and sealing surface flatness before shipment. Anti-rust primer and industrial paint are applied for corrosion protection during storage and transit.
Standard seal rings are stocked for all common Symons spring cone crusher sizes. Custom diameters and profiles are available for non-standard crusher configurations. Regular replacement of worn seal rings is essential for protecting the crusher's lubrication system and preventing costly bearing failures in mining and quarry operations.
Key Features
- Premium Cast Iron: HT250/HT300 cast iron provides excellent wear resistance and dimensional stability.
- Effective Dust Barrier: Labyrinth seal design blocks abrasive dust from reaching bearings and lubrication oil.
- Precision Machined: CNC-machined sealing surfaces ensure tight, consistent clearance for effective sealing.
- Extends Bearing Life: Prevents contamination that causes premature bearing wear and costly breakdowns.
- OEM Interchangeable: Fully interchangeable with original Symons cone crusher seal ring dimensions.
- Custom Sizes: Custom inner/outer diameter and profile to match your specific crusher model.
