Ball Transfer Units

Ball transfer units, also known as conveyor balls, are an ideal solution for the smooth and precise movement of loads in a range of applications. Ball transfer units are either surface-mounted, recess-mounted or spring-loaded. Mounting types for this transfer bearing component vary depending on application, with the ability to move both small and large loads with ease.

When using ball transfer units, always consider the weight for the intended use. Ball transfer units have a high maximum load, but this load is often distributed across many transfer balls, allowing for even larger loads to be moved with ease.

Ball transfer units are available in a range of materials such as aluminium, steel, and stainless steel with a range of ball materials including steel, PUR, and rubber.

Types of Ball Transfer Units

• Surface Mount: Ball transfer units can be fastened down and secured to a flat surface.
• Recessed Mount: Ball transfer units fit into pre-defined holes on conveyor setups. Some models allow the transfer unit to be dropped into place.
• Spring-Loaded: Ball transfer units are strengthened with a spring, which allows them to carry a high load capacity.

Fixing Methods of Ball Transfer Units

The fixing methods vary depending on your application and the specific design where you need to install your ball transfer unit.

Flange Fixing

Flange fixing typically involves a unit with a multi-hole base, allowing the ball transfer to be securely fastened to a flat surface using screws or bolts. This provides a robust and permanent installation suitable for heavy-duty steel ball transfer unit applications.

Thread Fixing

Units designed for thread fixing feature a threaded stem or stud, allowing for secure and often adjustable attachment to machinery or structures. This method offers flexibility and is ideal for mounting individual transfer bearings that require precise height adjustment.

Tube Fixing

Tube fixing is achieved by inserting the unit into a suitably sized tube or pipe. The unit, often equipped with ball transfer rollers, is then secured into place, typically via a spring washer mechanism, creating a durable fixture within conveyor setups.

Drop-In Fixing

Drop-in fixing offers the fastest installation. The ball transfer unit is simply placed into a pre-cut hole and can be further secured using a separate fixing clip. This method enables quick assembly and easy replacement of the ball transfer bearings when necessary.

Maintenance for Ball Transfer Units

To ensure your ball transfer unit continues to provide smooth, precise movement and a long working life, regular maintenance is essential.

Regular Inspection

Implement a schedule for routine checks of your ball transfer bearings to look for signs of wear, damage, or leaks. Identifying minor issues early prevents them from escalating into costly failures that could halt your material handling or assembly lines. Checking the condition of the main load ball and smaller support balls should be part of this process.

Lubrication

Ensure all moving parts, particularly the ball transfer bearings, are kept adequately lubricated. Proper lubrication reduces internal friction and heat build-up, which is key to preventing premature wear on the ball transfer mechanisms. When choosing a lubricant, always use the one recommended by the ball transfer unit manufacturer. For those using plastic solutions, there’s no need to add lubricant.

Cleaning

Keep your ball transfer unit and the surrounding area free from debris, dust, or contaminants. Accumulated grit can impair the smooth rolling action of the transfer bearing, thereby accelerating wear. Consult the manufacturer’s guidelines for the best cleaning methods, particularly for stainless steel ball transfer units.

Ball Transfer Unit Applications

Ball transfer units are utilised in numerous industries worldwide. They are suitable for moving loads that need to be moved smoothly and with minimum effort in any direction. Typical applications include:

Manufacturing and Assembly Lines

In manufacturing, ball transfer units are frequently integrated into conveyor systems and assembly lines to connect different machines seamlessly. They enable materials or products to be swiftly transferred or precisely rotated by workers, preventing damage and significantly improving the efficiency of high-volume production.

Air Cargo and Logistics

A common application is within roller decks at loading docks and airports. The use of ball transfer units simplifies cargo handling, allowing heavy containers and Unit Load Devices (ULDs) to be quickly loaded or unloaded from aircraft and trucks, often eliminating the need for separate lifting equipment.

Loading Docks and Material Handling

Ball transfer conveyors are frequently installed in loading docks to facilitate the rapid transfer of cargo directly onto or off vehicles, reducing manual labour and turnaround times. Meanwhile, the inherent strength of a steel ball transfer unit makes it ideal for handling heavy materials.

Food Processing and Cold Applications

For environments with specific temperature requirements, such as food processing, ball transfer units are particularly well-suited. The ability of a ball transfer unit to operate smoothly in low-temperature freezers or high-temperature cooking processes without traditional lubrication helps maintain hygiene and prevents materials from sticking.

Specialised Engineering

Ball transfer mechanisms are also used in mechanical engineering to enhance the manoeuvrability of machinery, and in the furniture industry to assist in moving heavy cabinets and tables. Additionally, the robust design of a spring-loaded ball transfer unit allows for higher load capacities in these demanding applications.
