Ball transfer units in a wide range of designs

The small castors are capable of doing great things. Not only do they transport heavy loads, they can also safely transport sensitive goods such as glass or fine sheet metal. Depending on the goods to be transported and the field of application, you can choose between different materials for the rollers. Each material offers different advantages.

The selection of high-quality materials and tight manufacturing tolerances ensure easy and precise movement of the goods to be transported. The ball transfer unit can be supplied in a wide range of housing designs, from galvanised steel and stainless steel to robust black galvanised steel. The balls are made of steel, galvanized steel, plastic, nylon or stainless steel, some of which are optional. The latter are not only corrosion resistant, but also resistant to various chemicals such as petrol, oils, alcohols and cleaning fluids.

Ball transfer units in a wide range of designs

The small castors are capable of doing great things. Not only do they transport heavy loads, they can also safely transport sensitive goods such as glass or fine sheet metal. Depending on the goods to be transported and the field of application, you can choose between different materials for the castors. Each material offers different advantages.

The selection of high-quality materials and tight manufacturing tolerances ensure easy and precise movement of the goods to be transported. The ball transfer unit can be supplied in a wide range of housing designs, from galvanised steel and stainless steel to robust black galvanised steel. The balls are made of steel, galvanized steel, plastic, nylon or stainless steel, some of which are optional. The latter are not only corrosion resistant, but also resistant to various chemicals such as petrol, oils, alcohols and cleaning fluids.

Applications for ball transfer units made of steel, stainless steel, nylon or plastic

The application areas of the castors are extremely diverse. These castors are often used as components in conveyor systems and assembly systems, as the integrated design ensures very high mileage and mobility. Especially in the field of conveyor systems, the ball transfer unit is frequently used in a variety of ways. Thanks to the possible changes of direction as well as the fast and above all almost force-free positioning of the goods to be conveyed, the ball transfer unit has established itself as a design element in many systems. From large and small manufacturing companies to airports or shipping service providers, numerous companies rely on flexible ball transfer units made of plastic, steel or stainless steel for the transport of goods. These castors are also increasingly being used in furniture assembly. This is because ball castors for furniture allow furniture to be positioned quickly and easily without the use of force.

Load limits and the load capacity of the ball transfer units

Our range includes a whole series of different castors with different load limits. This means that you can easily adapt the castors to your individual requirements and the weight of the elements to be transported. In our range you can choose from rollers with a load capacity between 12 and 2.000 kilograms per castor. In this way it is always possible to safely transport even large and heavy goods and workpieces using a corresponding roller system. If you have any questions regarding the calculation of the total load capacity of a system, please contact us. We will be happy to inform you about the various options and take care of the correct calculation of the maximum weight load for you.

Seals and sealing systems for ball transfer units made of plastic, steel or stainless steel

In order to protect the castors from soiling and to ensure their excellent rolling properties in the long term, the ball transfer units are equipped with various sealing systems, e.g. made of felt. Some types of ball transfer units are provided with dirt exit holes. Spring-loaded ball transfer units absorb impact energy and thus protect the loads and goods to be moved. This means that the castors can be used in a wide variety of applications without any problems and without permanent contamination and thus without any loss of performance of the castors. The long service life and the consistently high transport performance of the castors make them particularly valuable for industrial use. But also as ball transfer units for furniture, for example in production areas, the seal and thus the long-term usability of the castors plays an important role. For this reason, we at BS Rollen make sure that all ball transfer systems have appropriately dimensioned sealing systems with a high degree of efficiency. This means that our customers can always and permanently rely on our ball transfer systems and benefit from them.

Comprehensive range of ball transfer units to choose from

Our range includes many different versions of the ball transfer unit in various designs. Particularly popular and frequently used are, for example, ball transfer units made of steel or stainless steel, which are characterised above all by their very high load capacity and enormous load limits. We also offer castors with different mounting options. The roller housings can be fastened in many different ways: for example with set screws and studs from above or below, alternatively they can be inserted into holes. Some are fitted with round or square flanges. This ensures flexible fastening in a wide variety of systems and applications at all times. Because it is only through secure and stable fastening that the ball transfer unit can exploit its full conveying potential and provide the desired transport services.
