Berserker F695-2RS ABEC9 Grade Bearings - Hybrid Ceramic Bearings (SF695C-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.

The Berserker F695-2RS ABEC9 Grade Hybrid Ceramic Bearings from West3D are engineered for demanding 3D printer motion applications like Voron 2.4, Trident, and other CoreXY builds. 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 over 120°C. Their ABEC9 rating ensures tighter tolerances (0.0012 mm eccentricity) than typical 3D printer bearings, reducing vibration and improving layer consistency in high-speed printing.

Why Upgrade?

• Reduce layer artifacts and vibration in high-speed CoreXY printers like Voron 2.4 and Trident
• Extend motion system lifespan with corrosion-resistant hybrid ceramic materials
• Maintain smooth, precise motion at high RPMs for improved print quality
• Benefit from tighter ABEC9 tolerances compared to common ABEC7 bearings
• Operate reliably in elevated temperature environments up to 120°C continuous

Best For:

• Voron 2.4 and Trident builders upgrading motion system bearings
• CoreXY enthusiasts seeking high precision and durability
• Users replacing worn or noisy F695-2RS bearings in 3D printer linear rails
• High-speed 3D printer builds requiring stable, low-friction motion
• Motion system upgrades in DIY and custom CoreXY printers

Pair With the Right Filament

High-precision motion enabled by these bearings pairs well with filaments requiring consistent extrusion and smooth layer transitions.

• PLA Filament — ideal for testing motion smoothness and print quality improvements
• PETG Filament — benefits from stable motion for better layer adhesion
• TPU Flexible Filament — requires precise motion control to avoid print defects
