Ball Transfer unitsWe supply a range of Ball Transfer Units here at Townsend Bearings.

Ball transfer units consist of a large ball seated on a quantity of small ball bearings in a hemispherical cup.

There are many types of Ball Transfer Units, such as the flange fitting and the European type. The flange fitting consists of Zinc plated pressed steel with carbon steel balls and also stainless steel body with stainless balls. This type has three holes.
The European type is very similar to the flange fitting. With Zinc plated pressed steel with carbon steel balls and
stainless steel body with stainless balls. The difference is the main cup, which is manufactured from toughened steel.
