When a seized bearing brings your project to a halt — whether it's a skateboard wheel, a small motor, or a precision instrument — finding the right replacement fast matters. These deep groove ball bearings are designed for engineers, hobbyists, and maintenance professionals who need consistent, low-friction rotation across a wide range of equipment.
Each bearing follows the standard 6000, 6800, or 6900 series designation, covering bore diameters typically ranging from 10 mm to 50 mm (approx. 0.39" to 1.97"). Available in two seal configurations — Iron Seal (open/metal shielded) for dry or lubricated environments, and Rubber Seal (RS/2RS) for dusty or wet conditions — and sold in quantities from 1 to 10 pieces per order.
These thin-walled deep groove ball bearings suit a broad range of use cases: replacing worn bearings in electric motors and power tools, upgrading inline skate or skateboard wheels for smoother rides, and supporting precision shafts in 3D printers, CNC machines, and robotics builds.
Iron Seal (metal shield) suits clean or pre-lubricated environments; Rubber Seal (2RS) blocks dust and moisture for outdoor or industrial use.
Covers 6000, 6800, 6900, and 16000 series — bore diameters from approximately 10 mm to 50 mm (0.39" to 1.97") to match common shaft sizes.
Slim cross-section reduces weight and space requirements, making these ideal for compact assemblies in robotics, drones, and precision instruments.
Deep groove raceway geometry supports both radial and moderate axial loads, delivering smooth, consistent rotation at low to moderate speeds.
Order 1, 3, 5, 7, or 10 pieces per SKU — stock up for maintenance kits or grab a single replacement without overspending.
Suitable for electric motors, power tools, inline skates, 3D printers, CNC spindles, bicycles, and general machinery maintenance.

Match the bearing number to your existing part or measure the shaft (bore), housing (outer diameter), and available width. The 6800 series is the thinnest, 6900 is mid-range, and 6000 is the most common general-purpose series. Select your size from the Sizes dropdown above.
Iron Seal (metal shield) bearings are open on one or both sides and are suitable for clean, dry, or re-lubricated environments. Rubber Seal (2RS) bearings are fully enclosed with rubber contact seals, making them resistant to dust, dirt, and light moisture — ideal for outdoor equipment or dusty workshops.
Yes. These bearings use chrome steel (GCr15) raceways and balls, which provide solid radial load capacity for small to medium motors, power tools, and similar rotating machinery. For high-speed or heavy-load industrial applications, verify the dynamic load rating against your specific requirements.
For wet or outdoor use, select the Rubber Seal variant. The 2RS rubber seal significantly reduces water and contaminant ingress. Iron Seal variants are not recommended for wet environments without additional external sealing or frequent re-lubrication.
Many skateboard and inline skate wheels use 608-series bearings, but the 6800 and 6900 series in this listing fit a wide range of wheel hubs and axle sizes. Check your wheel's bore diameter and confirm the size before ordering. The rubber seal option is recommended for outdoor skating use.
Select the quantity that matches your project: 1 piece for a single replacement, 3 or 5 pieces for a small repair kit, or 7–10 pieces for maintenance stock or multi-axis builds (e.g., 3D printers, CNC machines). Larger quantities are priced per-pack and offer better value per bearing.
The available sizes span the 6800 (10 mm bore), 6900 (10 mm bore), 6000 (10 mm bore), and 16000 series, with outer diameters and widths varying by series and size number. Use the Sizes dropdown to select your specific bearing number, then confirm dimensions against your application's datasheet.
