GRAE30-208 Spherical Outer Insert Ball Bearing With Eccentric Lock Collar Double Lip Seal C3 Clearance 30x80x42.1mm Farm Equipment

The GRAE30-208 spherical outer ring insert ball bearing adopts eccentric locking collar structure, double-sided composite multi-lip rubber seal and C3 enlarged internal clearance. Its spherical outer surface realizes self-aligning function to compensate shaft installation deflection, widely applied to agricultural machinery, conveying equipment and light construction machinery with dusty, muddy and heavy vibration working conditions.

• Spherical outer ring self-aligning design offsets shaft installation deflection, avoids abnormal abrasion caused by misalignment
• Eccentric locking collar + M8 grub screw double anti-loosening structure, firm shaft fixing, easy disassembly and maintenance
• Double-sided composite multi-lip seal with outer steel shield effectively blocks mud, crop debris, dust and water splashes in harsh farm environment
• C3 enlarged clearance reserves thermal expansion space, prevents bearing seizure under long-time high-temperature vibration operation
• Polyamide lightweight cage reduces rotation inertia and heat generation, stable continuous heavy-load running
• Pre-filled high-viscosity anti-washout long-life grease, extends relubrication maintenance cycle
• Standard metric interchangeable size, fully matched with universal bearing housing for conveyor and agricultural equipment
• Custom options: triple lip heavy mud-proof seal, corrosion-resistant coating, greasable lubrication port

👉 Greatly reduce premature bearing failure rate and cut long-term maintenance cost of agricultural and conveying machinery

This self-aligning eccentric lock insert bearing is widely used in:

• Agricultural tractors, rotary tillers, seeders and harvester transmission rotary assemblies
• Automated conveyor belts, packaging production line roller support parts
• Light construction compact rollers, mixing equipment and small lifting machinery
• Ventilation fans, textile processing equipment and outdoor transport machinery

👉 Ideal for customers seeking heavy-seal self-aligning eccentric lock insert bearing solutions

• 25+ years experience in spherical eccentric lock insert ball bearing manufacturing
• Exported to many countries worldwide
