22318E1C4 Double Row Spherical Roller Bearing 90x190x64mm C4 Extra Large Clearance

1. Product Overview

22318E1C4 double row spherical roller bearing, standard metric dimension 90×190×64mm.

Code Definition

• 22318: Medium heavy spherical roller base model
• E1: Optimized pressed steel cage for high load & vibration
• C4: Extra large radial clearance for high temp & vibrating working conditions

Spherical outer raceway delivers excellent self-aligning performance to compensate shaft deflection and installation misalignment. Double row symmetric rollers carry heavy radial load and bidirectional axial load simultaneously. Outer ring equipped with lubrication groove and holes for convenient relubrication. C4 enlarged clearance eliminates thermal expansion clamping under continuous high-temperature vibration, widely used on vibrating screens, stone crushers, mining conveyors and heavy industrial mixers.

2. Technical Specifications

Drawings and vibration cycle durability test reports available on request.

3. Core Advantages

• Self-aligning spherical design tolerates shaft deflection and mounting misalignment
• E1 reinforced steel cage stable under continuous heavy vibration
• C4 oversized clearance prevents seizure at high operating temperature
• Dual-row roller layout provides ultra high radial & bidirectional axial load capacity
• Outer ring lubrication groove and holes support easy on-site relubrication
• Low friction smooth rolling reduces heat generation for long continuous operation
• Unified standard dimensions for direct one-to-one replacement
• Customizable precision grade, special high-temp grease and laser marking
