Meet the 30x41x6.5 mm Deep Groove Ball Bearing—the compact, precision-engineered solution designed to deliver smooth, reliable motion in tight spaces. With a 30 mm bore, 41 mm outer diameter, and a slim 6.5 mm width, this bearing is built to fit where space is at a premium while still providing robust performance.

Why this deep groove ball bearing stands out

• Compact yet capable: The 30x41x6.5 mm footprint makes it ideal for small motors, hobby robotics, 3D printers, and other space-constrained assemblies without sacrificing load capacity.
• Balanced radial and axial support: Deep groove geometry accommodates radial loads with the ability to take light axial loads in both directions, offering versatile mounting in various orientations.
• Consistent, quiet rotation: Precision-machined raceways and steel balls ensure smooth operation with reduced friction, helping your machine run more steadily and with less vibration.
• Durable, reliable construction: Made for repeated cycles and longer life in everyday equipment, this bearing is designed to withstand the rigors of continuous use in hobbyist and light-industrial projects.

Ideal use cases

• 3D printer axis and extruder assemblies where space is limited but dependable motion is essential.
• Small robotics joints and drive systems that require smooth rotation with minimal play.
• Compact CNC components, such as small gantries or rotary tables, where precise alignment matters.
• hobby motors and gearboxes in DIY projects that demand reliable support without bulky hardware.
• Conveyor and pulley systems in compact machinery where a tight, efficient bearing is a must.

Installation and maintenance tips

• Verify bore compatibility: ensure the shaft diameter is 30 mm for a proper, secure fit.
• Clean and inspect: start with a clean housing to prevent contaminants from entering the raceway during installation.
• Lubrication awareness: select an appropriate lubricant for the operating environment; proper lubrication minimizes wear and extends life.
• Fit and preload: seat the bearing evenly and avoid over-tightening fasteners, which can induce uneven loads and reduce performance.
