About this deal

Another key characteristic of roller table motors is the ability to dissipate heat. This relates to the load, acceleration and frequency of starts, plus – importantly – a factor to account for the thermal consequences of stalls. Within the industry, this is referred to as the ‘B value’ and is always quoted on technical specifications because of its fundamental importance. We can offer frames to provide a natural fall over a required distance. Where distances become too great, powered conveyors should be considered. The ball unit table is the perfect connecting piece at branches and intersections in a conveyor system with a multidimensional configuration.

This can be particularly apparent when using smaller diameter PVC conveyor rollers. To combat this, heavy-duty conveyor rollers can be used with greater tube walls, bearing load capacities, and axle diameters. The weight of the product when traveling over the minimum supporting rollers, should not exceed the total capacity of the conveyor rollers in question. Heavy components can be optimally aligned for the next processing step by employees – for example, before being fed into a machine. Just like they are for the belts, the weight and dimensions of the goods to be transported are the decisive criteria. The weight of the heaviest good is important for the required load-bearing capacity of the individual ball units. You can calculate this factor as follows:

Roller conveyors: using gravity to reach a destination with flexibility

Size: Choose a table that is appropriate for the size of your workshop and the types of projects you will be working on. For many years AC motors have been preferred for roller table applications because they require less maintenance than DC motors and the use of inverter drives is well-proven in the field.

The dimensions and properties of the goods you usually need to convey form the focus of your selection – which, incidentally, also applies for skate wheel conveyors and ball unit tables. In this case, you shouldn't just think about the number of metres, but instead, also factor in the free space required to the left and right of the belt, or space for intersections and distribution points to other elements and components of the conveyor technology. Weight capacity: Make sure the table can support the weight of the material you will be working with. A ball unit table is an extension unit for roller conveyors, conveyor belts and other products from our range of products for conveyor technology. Its function is as simple as it is clever: instead of moving transport goods in one direction only, the items can be moved in any direction at the same level on the ball units with individual bearings. You'll always profit from this when the goods don't just need to be moved from one place to another, but also need further work: This is why it's important to consider the maximum and minimum product sizes that will be used on the conveyor. If items are too small for the roller conveyor, it can be an advantage to use totes for smaller products. It is also common to see companies using baseboards for items, to cover a larger surface area.

2 Metre Heavy Duty Workshop Roller Table - 7 Rollers - Excellent Value

Roller tables are a type of woodworking equipment that are designed to help support and move long pieces of lumber or sheet goods during the woodworking process. They consist of a series of rollers that are mounted on a frame, which can be adjusted to the desired height. Roller conveyors are most effective when a company installs ones that operate only by using the force of gravity on a gradient between two and five percent. This allows them to unfold all the advantages they offer in an optimal way: Roller tables can also be used as a standalone piece of equipment for tasks such as assembling or sanding large projects. They can be adjusted to the desired height, making it easier for the operator to work on the project without having to bend or stoop. Increasingly, there is also an emphasis on energy efficiency, as a set of table roller motors will consume a considerable amount of power. The basis of this is often the use of a cast aluminium rotor and careful design of other elements of the electrical engineering. Once the correct gravity roller conveyors have been selected, it will need to be mounted on a set of suitable support frames.

Roller tables require special motors with a high dynamic constant, plus a robust overall design to withstand the extreme heat and dirt of a steel mill. Such motors are used throughout the rolling mill on general conveying duties, but on the reversing mill and associated approach tables, the operating duties are extreme with constant stop/starts and instant reversal of directions. The required fall on the roller conveyor will depend on the weight of the product traveling down the conveyor.We offer our conveyor technology as a modular system. This ensures you have the highest possible level of flexibility and can determine your need for straight sections, curves or connecting passages individually. The straight elements are then used for form the core of the conveyor belts, and therefore also form the basis of your needs assessment. In cases like this, the gravity-based solutions will prevail everywhere that your employees need access to a transported good – for example, to unload or load an item, prepare it for shipment, or use it for other purposes. Of course, there is also the option of having your entire conveyor system planned by our CAD service. We're more than happy to answer your questions on this in person. The wider a roller tube becomes the weight distributed over the roller causes deflection in the material. This means that the conveyor bearings will not be working to their full load capacity. Roller tables are commonly used in conjunction with other woodworking equipment such as table saws, planers, sanders and cross cut saws (to name a few!). They can be used to help support the weight of long pieces of lumber or sheet goods as they are fed through these machines, making it easier for the operator to handle the material and reducing the risk of damage.
