ball transfer units are composed of a large precision ball rolling on a bed of small precision balls seated in

a hardened hemispheric cup.

All balls are ground and heat treated; they start moving when the main big ball (which is made of hardened

steel, stainless steel or plastic) rolls, to let it move with the lowest possible friction and guarantee a regular

movement. This kind of construction allows moving with small effort any kind of heavy material, whose surface

is plain, smooth and rigid enough.

Friction is extremely reduced and a smooth movement is provided at a speed of 2m / sec. In this way, very heavy

loads can be easily moved.

Our production range includes different kinds of ball transfer units, starting from a main supporting ball's

dimension of 8 mm up to a maximum of 90 mm in steel, stainless steel or polyacetal plastic material, and loading

capacities from 15 kg to 2000 kg. Basically there are two kinds of products: Machined Heavy Duty units (studied

for heavy shock loads and long life applications), and Pressed Light Duty units (suitable for light loads). The

housings of the units are bright metal zinc plated or completely stainless steel made and they incorporate self

cleaning bottom holes and oiled felt sealing system (except SP8-12-15-25). This is available on request on SP

15 and 25 series only. We can also provide ball transfer units with main balls made of AISI 440C, AISI 304, AISI

316, teflon, glass, with various coupling between big and small balls.
