608 Rubber Bearing Wheel - 30mm Polyurethane Tire with 8mm Bore

The 608 Rubber Bearing Wheel is a compact, low-noise wheel assembly built around a standard 608 ball bearing, designed for robotics, DIY carts, skates, and light industrial motion projects. The wheel uses a 30 mm outer diameter with a 9.5 mm thickness and an 8 mm shaft bore, allowing it to mount directly onto common 8 mm axles without additional adapters. Its tread is made from a durable rubber-polymer composite that dampens vibration and reduces rolling noise, while the flat tread profile improves stability and tracking on smooth surfaces. The integrated 608 bearing (8 mm inner diameter, 22 mm outer diameter, 7 mm width) is an open-style ball bearing rated for high rotational speeds and dynamic loads, and the complete wheel assembly is rated for a maximum load of 100 kg. The black finish and precision bearing seat make this 608 bearing wheel suitable for robot chassis, luggage replacements, sliding tracks, and workshop fixtures. Whether the application is a differential-drive robot, a custom conveyor, or a rolling display stand, this rubber wheel with bearing provides a practical balance of low cost, quiet operation, and dependable load capacity.

Application

1. Robot chassis and differential-drive platforms requiring compact, low-noise wheels.
2. DIY carts, trolleys, and rolling stands for workshop or household use.
3. Luggage, suitcase, and case replacement wheels with 8 mm axles.
4. Sliding track, guide-roller, and door/window pulley systems.
5. Light-duty conveyors and prototyping fixtures where a 30mm rubber wheel is sufficient.
