Ball Transfer Units BTU-C & BTU-D
ISUTAMI BTU-C and BTU-D ball transfer units are a multi-directional, material handling system. Moving in all directions, ball transfer units enable the easy transfer of light and heavy loads – changing the direction of motion instantly. They consist of a large load-bearing ball which sits upon many smaller balls encapsulated in a semi-spherical cup. The design greatly reduces friction and allows heavy loads to be moved with a minimum of effort.
