Berserker 625-2RS ABEC9 Grade Bearings - Hybrid Ceramic Bearings (S625C-2RS)

CoreXY and high-speed 3D printer builders know that bearing precision directly impacts motion smoothness and print quality — low-grade bearings cause layer inconsistencies and premature wear in motion systems. Without high-tolerance bearings, printers like Voron 2.4 or Trident risk increased backlash and reduced accuracy during fast moves.

The Berserker 625-2RS ABEC9 Grade Hybrid Ceramic Bearings from West3D are engineered for demanding 3D printer motion systems. Featuring polished AISI400C stainless steel races, AISI304 stainless steel cages, and Si3N4 ceramic balls pre-lubricated with AF2# oil, these bearings operate reliably at speeds up to 40,000 RPM and temperatures exceeding 120°C. Popular among Voron, Trident, and other CoreXY builders, these ABEC9-rated bearings offer tighter tolerances (0.0012 mm eccentricity) than typical ABEC7 options, ensuring smoother, quieter, and more precise motion in your 3D printer's linear rails and extruder assemblies.

Why Upgrade?

• Reduce layer artifacts caused by bearing play in high-speed CoreXY printers like Voron 2.4 and Trident
• Extend motion system lifespan with corrosion-resistant hybrid ceramic bearings
• Maintain smooth, quiet operation at high RPMs and elevated temperatures
• Improve print accuracy by minimizing eccentricity and mechanical backlash
• Compatible with demanding DIY and premium 3D printer builds requiring precision motion

Best For:

• Voron 2.4 and Trident builders upgrading linear rail bearings
• CoreXY enthusiasts seeking high-performance motion components
• Users replacing worn or noisy bearings in extruder and idler assemblies
• High-speed 3D printer builds requiring ABEC9 tolerance bearings
• DIY and custom printer projects demanding durable, low-friction bearings

Pair With the Right Filament

High-precision motion enabled by these bearings pairs well with filaments requiring consistent extrusion and minimal vibration.

• PLA Filament — ideal for smooth, detailed prints benefiting from precise motion
• PETG Filament — compatible with higher temperature printing and reliable extrusion
• TPU Flexible Filament — smooth motion reduces issues when printing flexible materials
