Ball Transfer Units BTU-F

Ball Transfer Units BTU-F
ISUTAMI BTU-F ball transfer units are a multi-directional, material handling system, consist of a large load-bearing ball which sits upon many small balls encapsulated in a hemi-spherical cup. The housing can contain a seal to clean the load ball as it rotates. The design greatly reduces friction and allows heavy loads to be moved with a minimum of effort. BTU-E ball units may be used at any orientation but deviation from the vertical may result in a reduction in the load ratings.

Ball Transfer Units BTU-F Features

BTU-F ball transfer units make light work of shifting, rotating and directing unit loads. They have proven extremely valuable as integral parts of conveyor systems, feed devices, and machining and packaging equipment. Ball transfer units are designed so that precise rolling and full load-bearing capability are ensured in any mounting orientation. BTU-E ball transfer units have oil-soaked felt seals to keep from dust, dirt, rust and acid. Galvanized housings, internals and steel balls enable all of these elements to offer enhanced anti-corrosion protection.

The BTU-F series currently has only one model BTU254-F, and its bottom has a concave surface to fit on the platform. The top of the table has a flange. The BTU254-F steering ball diameter (d) is 1'', which is the same as that of BTU254-E and BTU254-G. The overall diameter of the product (D, including flange) is 1.84’'. The total height (L) of the product is 1.34'' and the product mountable height (H) is 0.87''.

The BTU-F units have the listed five advantages below:
Easy to install and extract;
Consistently high quality;
High rationalization effect;
Smooth operation;
Precise scrolling and complete load carrying capacity.

BTU-F universal ball can be customized according to customer requirements, applicable fields: cargo and baggage handling, assembly line, casters, machine loading, sliding door system, machine table, etc.
