1. What sizes are Rotacaster multidirectional wheels available in?
At this point in time rotacaster manufactures both a 125mm (5”) diameter wheel and 48mm (1.9") diameter wheel which was released in November 2009. Our current product development map includes six (6) omnidirectional wheel sizes ranging from 48mm (1.9”) to 300mm (12”) in diameter. We can expedite development of specific wheel sizes dependent on specific customer requirements and demand. If you have specific requirements, please contact us to discuss your needs or subscribe to our newsletter so we can keep you updated on developments.
2. Are Rotacaster multidirectional wheels available in a different colour?
Yes. Subject to custom orders (P.O.A). Rotacaster 125mm (5") wheels come in the standard grey colour you see on the website whilst our 48mm omni wheels come in the standard red rollers, black body that is displayed. However if you would like a ‘corporate’ colour or standard black we can accommodate your requests. Please contact us for details (minimal order quantities do apply).
3. What are Rotacaster multidirectional wheels made from?
The current 125mm Rotacaster omni wheels are manufactured from engineering grade polymers. The body is made from carilon, the bushes from nylon and the rollers from elastomers (polyurethane). Our new 48mm multidirectional wheel is manufactured using glass filled nylon for the body and axles and Delrin bushed polyurethane (TPU) rollers. Should you require custom roller materials, e.g. rubber, we can usually accommodate these requests depending on order quantities (P.O.A).
4. How strong/hard wearing are Rotacaster multidirectional wheels being plastic?
This is a very common concern, however Rotacaster omni wheels are an extremely robust and hard wearing product. Manufactured from injection moulded engineering grade polymers, the wheel body incorporates both the hub and transverse roller axles. This monolithic web-like structure provides a robust and resilient frame which can handle substantial dynamic (impact) and static (carrying) loads without failure. The subsequent over moulding encapsulates the bush and axles (with a durable roller material such as polyurethane). The omnidirectional wheels are then sonically welded together to form double or triple rotacaster wheels. The wheels are then ultimately mounted within a fixing leaving little chance for anything to break or malfunction.
The result is a wheel that offers:
superior strength, wear and friction characteristics
outstanding chemical resistance and low permeability
high resistance to fatigue, creep, swelling and repetitive deformation
excellent balance of stiffness and toughness over a wide temperature range
resistance to a variety of fuels, organic solvents and aggressive aqueous media
We encourage you to read the case study on the performance of the Rotacaster wheel in an abrasive and corrosive environment over a 2 1/2 year period in which the prior nylon swivel castors had been replaced every 6 months.
5. What configurations do Rotacaster multidirectional wheels come in?
Rotacaster multidirectional wheels are manufactured in a single, double or triple row configurations for the 125mm wheel whereas, at present, only a double configuration exists for the 48mm wheel. Single wheels are only for use when combined in multiples to either create a roller or a conveyor transfer table.
6. Do I need a swivel base?
No. The rollers take the place of a swivel mount, providing omnidirectional movement whilst using a fixed mounting. This also provides other benefits in regard to mounting options, load stability, improved tracking capability, minimal housing enclosures and simple mounting using the axle bolt.
7. What are the rollers on the Rotacaster multidirectional wheel made from?
The rollers on the Rotacaster multidirectional wheel are made from polyurethane as a standard, however custom requirments are available for particular enviromnments depending on volume orders.
8. Can I use a single Rotacaster multidirectional wheel as a floor wheel?
Yes, but only when combined in multiples to ensure that the combination provides a complete circular circumference so the contact surface of a roller maintains the concentric or circular bearing surface. The single wheel is predominantly for use as a driven wheel combined with others in conveyor transfers.
9. Will Rotacaster multidirectional wheels move sideways when unattended?
No, not on an even flat surface. Because the Rotacaster omni wheel uses a 20mm (3/4”) roller for sideways movement and has a fixed orientation, it requires a greater applied force in the roller direction than in it’s primary orientation (using it’s 125mm (5”) diameter). This is the case whether the force is manually or mechanically applied or by gravity such as on inclines. Therefore it will travel in it’s primary direction at a greater rate than it will in it’s secondary roller orientation. Dependent on the level of incline, load and speed, the rotacaster wheels will generally track directly across traffiicable inclines with minimal crabbing and in many cases allow loads to be parked on an incline with no (or minimal) applied braking (see video). For this reason it provides a much more controllable handling solution when negotiating inclines than swivel castors.
10. How do Rotacaster multidirectional wheels handle travelling across an incline?
Please refer to question #9.
11. Can I use more than four Rotacaster multidirectional wheels on a load platform, hand trolley or hand cart?
Yes, you are no longer restricted to the traditional 4 corner point fixing. The great thing with the Rotacaster multidirectional wheel is that each wheel acts individually and allows as many wheels as required to share the load without the need to overcome the mechanical coupling bond created when swivel castors are not aligned with one another or need to be reversed, (within reason – a person can not physically push 5 ton). You can add several Rotacaster omniwheels to provide the level of manouverability you require without the need for larger wheels and you can even mount Rotacaster wheels at 90 degrees to one another (click to see photo).
12. Are Rotacaster dollies available in different sizes?
Yes. Due to customer demand and feedback, we have recently extended our rota dollie range to include a small dollie, a dollie and three sizes of platform trolley. We also offer some standard accessories that can be used to customise your dolly. Please visit the Dollies and Multi-Skates page or contact us for more information.
13. Where are Rotacaster multidirectional wheels made?
The 125mm (5”) Rotacaster omni wheel is currently manufactured in Tuncurry New South Wales, Australia whilst our new 48mm (1.9") omni wheel is manufactured in the United States. We will be looking to transport the tooling for the 48mm wheel to Australia once some minor adjustments have been made.
14. Is the Rotacaster multidirectional wheel available with a brake mechanism?
No, Not at this point in time, however it is high on our product development agenda. We do recommend the use of readily available floor lock. There are generally 2 types, a friction lock or a lifting type lock. Please contact our sales team if you are unsure and they will help you choose the product that is right for you.
15. Can Rotacaster multidirectional wheels be driven in a conveyor transfer application?
Yes. The Rotacaster 48mm (1.9") wheel or the 125mm (5") single wheel can be fitted to a keyed shaft which can then be driven in conveyor transfers.
