MaxFind 90mm 78A Wheels Mobility Wheel Units (MWU) with DeepDream 608 2RS Bearings  (set of 8 wheels)

The Mobility Wheel Units (MWU) provide non-motorized rolling support for Mecha mobility systems that utilize skateboard-style truck assemblies or similar modular wheel mounts. These wheels are designed to deliver smooth rolling performance, traction on paved surfaces, and shock absorption when operating on asphalt or concrete.

Each wheel is paired with high-speed 608-2RS sealed bearings, creating a complete wheel-and-bearing mobility assembly suitable for integration with Mecha mobility platforms, robotics test rigs, and experimental vehicles.

MWU-520/MaxFind 90mm 78A Non-Motorized Wheels with DeepDream 608-2RS Bearings

The MWU-520 wheel module combines high-rebound polyurethane wheels with sealed precision bearings for reliable and low-friction rolling performance.

Wheel System

Maxfind 90mm PU Wheels

The MaxFind wheels are manufactured from polyurethane (PU) and feature a 90 mm diameter and 78A durometer rating, providing a soft compound that absorbs vibration and improves traction on pavement surfaces.

The larger wheel diameter helps the platform roll more smoothly over cracks, debris, and uneven pavement compared with smaller wheels. The 60 mm wheel width increases the contact patch with the ground, improving grip and stability during movement.

Bearing System

DeepDream 608‑2RS Skateboard Bearings

Each wheel is fitted with 608-2RS sealed ball bearings, a standard bearing format widely used in skateboards, scooters, and inline skates. These bearings use dual rubber seals to protect the internal raceway from dust, debris, and moisture while retaining lubrication for smooth rotation.

Typical 608-2RS bearings have the following dimensions:

• Inner diameter: 8 mm
• Outer diameter: 22 mm
• Width: 7 mm

The sealed bearing design supports high-speed rotational operation while reducing friction, vibration, and maintenance requirements.
