“Miniature” ball transfer units available from SKF® provide solutions to transfer and position small parts easily and smoothly in material-handling settings where maneuvering room may be restrictive. They offer practical alternatives to cumbersome carts, casters, and related bulky equipment and install quickly and securely using studs to create “rolling surfaces” on which small parts can travel.
These lightweight, compact, and ready-to-install miniature ball transfer units enable reliable movement of equipment or devices for a wide range of industries, including microelectronics, medical/biotech, semiconductor, and food processing industries, among others. Upon installation, they allow for 360º movement and associated versatility.
Depending on type, “miniature” ball transfer units are designed with ball sizes ranging from 4.8mm to 9.6mm. They feature flat top steel housings with either steel or stainless steel load balls or angled top aluminum housings with stainless steel load balls. Units offer high load ratings from 10kg to 70kg (up to 154 lbs.).
Despite their relatively small size, the units are engineered for durability, high performance, and long service life.

Arthur Whitehead says
Looking for a ball transfer unit that I can mount to the bottom of my fireplace screen that will keep the edge of screen from dragging on a granite ledge as I open/close the screen. The bottom of the screen where I need to attach the unit is to an edge that is 3/8th” to 1/2″ above the granite. I would like the unit to have a vertical shaft that can bolted through/to the bottom of the horizontal part of the screen which is 37″ long, 1/2″ wide and 1/16th of an inch thick-wrought iron. While the ball transfer unit will never be directly in the fire, it must be able to work in a very warm environment.
If you can think of a better way of keeping this screen edge from rubbing on the granite shelf when I open/close the screen to put wood in the fireplace and to clean out its ashes, please feel free to suggest it.
