Product Description
Detailed Specifications & Features
Grooveless Bearing Disc Spring for Tapered Roller Bearings
Tapered roller bearings serve as critical components in heavy-load mechanical systems including construction equipment (excavator swing bearings), mining machinery (conveyor rollers), and industrial gearboxes, where axial preload management directly impacts operational safety and component longevity.
Key Features & Benefits
- Heavy load uniform preload - Solid annular structure with enhanced wall thickness (3.5-8.0mm) and high radial stiffness (280-450N/mm)
- Uniform load force distribution - ±2% load variance across bearing rollers when multiple thickened discs (4-12 pieces) are parallel-stacked
- Load multiplication with same displacement - Achieving load multiplication ratios of 4.2-6.8x at 1.2mm compression
- Extends bearing service life by 35% compared to conventional spring washers
- Prevents bearing axial play (<0.02mm) and improves assembly stability
