How to Choose the Correct Axle Bore Size?<\/strong>
\nBefore purchasing, please ensure you measure the correct dimension of your existing wheel to guarantee a perfect fit for your installation shaft or bolt (e.g., 17mm axle\/bolt).
\n\u2714\ufe0f Correct Measurement (Central Bore ID):<\/p>\n

\"Measure
\nYou must measure the Inner Diameter (ID) of the central bearing. To do this, insert the inside jaws of your caliper completely into the central hole.
\nStandard Option for WHILL Wheelchair\/AGV: 17 mm.<\/p>\n

\u274c Incorrect Measurement (Flange\/Bearing OD):<\/p>\n

\"measure
\nDo NOT measure the outside of the bearing flange or metal casing. For example, a measurement of around 30.84 mm represents the housing\/flange Outer Diameter (OD), NOT the installation hole size.
\nSpecifications & Compatibility
\nBearing Inner Diameter (Bore ID): 17 mm\u00a0 (Fits 17\u00a0 mm\u00a0 round shafts, step bolts, or M17 hardware).<\/p>\n

FREQUENTLY ASKED QUESTIONS<\/strong><\/p>\n

Q: Is this wheel an official Whill part?<\/strong>
\nA: No, this is a premium, fully compatible aftermarket replacement wheel manufactured to meet or exceed OEM specifications, allowing us to pass the savings directly to you.<\/p>\n

Q: Can this wheel be used for custom wheelchair DIY or AMR robotics?<\/strong>
\nA: Absolutely! Thanks to its heavy-duty load capacity and smooth omni-directional rotation, it is highly sought after for premium custom wheelchair conversion kits and industrial AMR\/AGV robotic platforms. Contact our support team for custom axle\/sleeve dimensions.<\/p>\n

Q: How often should I replace my front omni wheels?<\/strong>
\nA: For active everyday users, we recommend inspecting the micro-grooves and roller spin every 12 months. Replacing them in pairs ensures a perfectly balanced and aligned ride.<\/p>\n

\n
Q: My caliper shows 16.59mm instead of exactly 17mm. Will this fit my wheelchair?<\/strong><\/div>\n
A: Yes, absolutely!<\/strong> Standard 17mm bearings often measure around 16.6mm on digital calipers depending on the precision and positioning of the caliper jaws. It is designed to slide smoothly onto standard 17mm wheelchair axles.<\/div>\n
<\/div>\n<\/div>\n
\n
Q: Is this wheel suitable for outdoor pavements?<\/strong><\/div>\n
A: Yes.<\/strong> Our Omni wheels feature high-elasticity TPU rollers and double-shielded precision bearings. They provide excellent shock absorption over pavement cracks and thresholds, while keeping dust, hair, and outdoor debris out of the mechanism.<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
