What Caster Wheel do you Need?
A series of videos deigned to help you make the right decision when choosing our products. In this video we are going to look at some of the considerations that you need to make when choosing the right castor. Firstly you need to measure the wheel diameter, and remember the larger the wheel, the easier it is to move. Next choose the type of castor. Top plate, bolt hole or threaded stem. To decide this think about how you want to fix your castor to your unit and how much each castor is expected to carry.
Next you need your fixing dimensions. Measure your top plate dimensions in order to match any replacement castors. Alternatively measure your bolt dimensions or your threaded stem size. Also measure your fixing bolt size D1 shown in the graphic on screen. At Ross Handling we can supply fixing bolts and nuts. In order to measure thread size simply measure the diameter of the thread. 8mm diameter equates to a m8 thread. Top plate castors are fixed to your unit by four fixing bolts per castor.
Supplied separately. Bolt hold castors can attach either by using a threaded bolt or a tubular adapter. Threaded stem castors are supplied with a stem that can screw into your equipment. Heard the one about square pegs into round holes? Attaching castors into round and square tubes can be achieved by using bolt hole castors and castor tube adapters. We have a variety of sizes available in both square and round tubular expander fittings. To find out more just speak to a member of our team. Next you need to choose the right wheel material. As a general rule of thumb, its hard wheels for soft floor surfaces, and soft wheels for hard floor surfaces. Soft wheels are rubber and hard wheels are nylon and polyurethane. Pneumatic and puncture proof wheels also available from Ross Handling are ideal for outdoor applications. Then you need to decide the castor configuration: Swivel, swivel with brake, or fixed.
Please be aware that bolt hole castors are available in swivel and swivel with brake configurations only. There are numerous configurations available but here are three of the most common to help you decide the right configuration for you. Four swivel castors for the maximum maneuverability but may be difficult to control on a straight run and not ideal for heavy loads. Two swivel castors and two fixed castors, the most popular configuration as it provides the best control coupled with maneuverability. Two swivel castors with brakes and two fixed castors.
