FAQ
How to clean my casters?
Regular cleaning keeps your wheelchair rolling smoothly and extends the life of your bearings.
To clean your front wheels you have to:
1. Loosen the axle: Use your hex key (and flat wrench) to unscrew the axle bolt holding the caster wheel inside the fork.
2. Remove the wheel: Slide the axle out carefully and take the caster and any spacers out of the fork.
3. Clean all components: Wipe down the wheel, axle pin, and spacers. Remove tangled hair from around the bearing seals.
4. Reassemble and tighten: Place the wheel and spacers back into the fork, slide the axle through, and tighten the bolt securely.
To make the cleaning you will need a couple of tools. The detailed instruction with the list of tools and our tips and tricks you will find here.
Assembly tip:
Holding the wheel, spacers, and tools all at once can feel tricky on your first try. Rest the wheelchair fork on a stable surface or your lap to keep the parts aligned while sliding the axle back in.
How often should I clean my casters?
Generally speaking, with normal front castors usage, you should clean them on a monthly basis.
But, if you have pets, or long hair – it shoud be done more often, even once a week.
The most important is to observe the performance of the wheel and adjust the cleaning routine to your needs.
What are the differences between the Omobic front wheels: Tristar Alucore, Lotus Alucore, and Lotus Fibercore?
All Omobic front wheels are fitted with non-marking tyres and provide very low rolling resistance. The differences between them relate to the rim material, design, and tyre options.
Tristar Alucore: Featuring a shiny, polished silver or black aluminium rim, this is a user favourite. It is engineered with a high-performing PU tyre that offers extremely low rolling resistance and high durability.
Lotus Alucore: With a flower-shaped aluminium rim and a choice of a PU or rubber tyre, it provides both comfort and a good-looking design.
Lotus Fibercore: Thanks to a rim made of plastic, this is the lightest front castor in the Omobic lineup. It is designed with a flower-like rim pattern and is available in two different widths.
What sizes are Tristar Alucore wheels available in?
Tristar Alucore front wheels are available in the following sizes:
4”, 35mm, 5”, 35mm, 6”, 35mm.
