Ball Transfer Units

RE 82 910/2003-08 6

Technical DataBall Transfer Units have a steel housingincorporating a hardened ball cup.

The latter serves as a raceway for amultitude of small supporting balls.

The supporting balls roll against the ballcup when the load ball turns.

Ball Transfer Units are designed so thatprecise rolling and full load-bearingcapability are ensured in any mountingorientation.

Ball Transfer Units require little mainten-ance, and almost every type is protectedagainst dirt by an oil-soaked felt seal.

Corrosion, caused by moisture or chemicalattack, can lead to impaired functioning oreven failure of the Ball Transfer Units.

offer simple protection against corrosion.In this type, the supporting balls and loadballs are made from standard antifriction

Galvanized covers and housings bearing steel and are protected fromcorrosive attack by the lubricant.

Consistent coating of all internals and theuse of corrosion-resistant steels for theantifriction bearing elements, similar to

Galvanized internals, corrosion-resistant steel balls

ISO 683-17, ensures comprehensivecorrosion protection such as specifiedin ASTM B117-97.

All parts made from rust and acidresistant steel(Antifriction bearing steel to EN 10 088)

This type is selected if the conveyed articlesare abrasive and/or there is exposure to anaggressive environment, especially tochemicals.

Since all versions have been designed tomeet the high standards of ISO 281, eventhis type is unsuitable for underwater use.

Technical Data

The stated load capacities apply to allmounting orientations and relate to106 rotations of the load ball. In caseof prolonged periods of use at speedsabove 1 m/sec, an increase in tempera-ture and reduced nominal life must beexpected as a function of the load,especially for sizes 60 to 90.

Load capacity

Vmax = 2 m/secConveying speed

The figures in the column headed Preloadare most important when choosing the sizefor these types. The mass of the conveyedarticle is divided in this case by the numberof load-bearing Ball Transfer Units.

Spring-loaded Ball Transfer Units

To determine the load for a Ball TransferUnit, the mass of the conveyed article isdivided by 3.If the load ball height tolerances are well-correlated, it is possible, depending on thenature of the conveyed article, to also per-form the calculation based on the numberof load-bearing Ball Transfer Units.

Example:

Mass = 3000 N

Ball Transfer Unit load

F = = 1000 N

Determining the load forBall Transfer Units

How the Ball Transfer Units should bearranged depends on the undersurfaceof the conveyed article. For articles witha uniform, smooth undersurface, such asboxes and cases, the distance between theBall Transfer Units is calculated simply bydividing the smallest edge length by 2.5.

Example:

Undersurface of the conveyed article= 500 x 1000 mmDistance between Ball Transfer Units

a = = 200 mm500 mm2.5
