The 1-Inch Mini Nylon Caster Wheel is the perfect low-friction steering solution for small-scale robotic platforms. At Electrapac, we recommend this lightweight caster for 2WD (Two-Wheel Drive) smart car kits where a compact, 360-degree swiveling front wheel is required for maximum maneuverability.

Product Overview

Designed specifically for DIY hobbyist electronics, this 1-inch white nylon wheel provides a smooth, non-marking glide across flat surfaces. Because it is a "bearing-less" and "lock-less" design, it offers a cost-effective, maintenance-free solution for lightweight robots. The nylon construction ensures it won't scratch indoor flooring while providing enough durability for classroom and laboratory testing.

Key Features for Electrapac Customers

• Zero-Turn Capability: The 360-degree swivel allows your robot to turn on a dime, making it ideal for obstacle avoidance and line-following projects.

• Low Profile: Its small 1-inch size keeps your robot chassis close to the ground, lowering the center of gravity for better stability at higher speeds.

• Maintenance-Free: Without internal ball bearings to grease or locks to jam, this caster remains reliable even in dusty environments or student workshops.

• Easy Mounting: The top plate features four pre-drilled holes, making it compatible with the standard M3 screws and brass standoffs found at www.electrapac.com.

• Universal Compatibility: Fits perfectly onto the front or rear of the 2WD Acrylic Smart Car Chassis or custom 3D-printed robotic frames.

Installation Tip

When mounting this caster to your Electrapac robot chassis:

Pro Tip: Use M3 Brass Standoffs to adjust the height of the caster wheel. This ensures your robot sits perfectly level with the rear drive wheels (usually 65mm), preventing the chassis from dragging on the floor.

Primary Applications

• 2WD Smart Cars: Acts as the "third wheel" (balancing wheel) for Arduino-based rovers.

• Line Followers: Provides smooth steering for robots following high-speed tracks.

• Small Moving Platforms: Useful for lightweight sliding drawers or miniature transport carts in DIY projects.

• Educational Kits: A simple, understandable mechanical part for teaching students about pivots and friction.
