Small Dimensions for Precision Machinery and Tight Spaces

Miniature Ball Transfer Units are compact ball transfers designed for precision machines and automated equipment. They come in several types: standard, stepped, and flatside models, allowing you to choose the right mounting style for your application. Despite their small size, these units provide good load capacity, low friction, and long service life. They are ideal for robot arms, adjustment mechanisms, and small conveyor systems where space is limited.

Choice of Materials and Precision Manufacturing

The body and adjusting ring can be made from S45C carbon steel or SUS304 stainless steel. The main and secondary balls can be SUJ2 bearing steel or SUS304 stainless steel. Some models also use nylon or POM plastic for reduced weight and enhanced corrosion resistance. Surfaces can be nickel- or chrome-plated. If the main ball is not stainless steel, it is oiled before shipping. Regular maintenance is recommended. Manufactured to tight tolerances, these units move smoothly and are built to last.

Wide Range of Sizes – Some Carry Up to 1600 kg

This product line offers eight sizes, with outer diameters from 8 mm to 60 mm. Load capacities range from 10 kg up to 1600 kg, and mounting threads range from M5 to M24. For example, a 22 mm OD model supports 200 kg, while a 60 mm OD model supports 1600 kg. Despite these high load capacities, the units remain compact. A 15 mm OD model stands only 31 mm tall and weighs just 40 grams. Miniature Ball Transfer Units combine strength and light weight, meet high precision standards, and can handle rapid swinging and high speeds without failure.

Great for Robotics, Adjustable Fixtures, and Compact Conveyors

Use these units wherever smooth movement is needed in a confined space. They reduce maintenance time and help keep your equipment running longer. Miniature Ball Transfer Units are an excellent choice for medical devices, small assembly lines, and any application where every millimeter counts.
