F695-2RS Flanged Ball Bearing (5x13x4mm)

Product Description

The F695-2RS Flanged Ball Bearing (5x13x4mm) is an essential mechanical component for smooth, reliable motion in custom 3D printers and CNC builds. Widely known for its use in the popular Voron ecosystem—specifically in Mobius 2/3 extruders, belt idlers, and gantry motion systems—this miniature deep groove ball bearing delivers exceptional precision and low friction under high-speed loads.

The “2RS” designation indicates that this bearing features dual rubber seals. This is a crucial upgrade over open or metal-shielded bearings, as the rubber seals keep the internal factory lubrication locked in while effectively blocking out workshop dust, ABS/PETG micro-particles, and debris. The integrated outer flange provides a built-in hard stop, allowing the bearing to seat perfectly and securely inside 3D-printed ABS parts or CNC-milled aluminum brackets without slipping axially.

Manufactured from high-quality bearing steel, it guarantees high durability, quiet operation, and minimal runout, making it the perfect choice for high-speed coreXY machines and precision filament extruders.

Key Features

• Dimensions: 5mm Inner Diameter (ID) x 13mm Outer Diameter (OD) x 4mm Width.

• Flanged Design: The extended lip ensures secure, slip-free seating inside printed parts and mechanical assemblies.

• Dual Rubber Sealed (2RS): Completely sealed on both sides to retain grease and block out workshop dust and plastic debris.

• Deep Groove Construction: Handles both radial and light axial loads efficiently.

• High Precision: Engineered for low-friction, high-speed, and low-noise operation in demanding 3D printer environments.

Applications

• Voron Design 3D printers (Mobius extruders, Clockwork extruders, gantry idlers)

• Custom DIY 3D printer belt pulleys and motion systems

• Small-scale CNC machinery and robotic joints

• Replacement of worn or grinding bearings in standard FDM extruders
