General product information | Ball Transfer Units 5 5 Directives and standards: Rexroth Ball Transfer Units are suitable for dynamic and static applications. All users must comply with a series of standards and guidelines. The standards can vary significantly worldwide. It is therefore essential to understand the legislation and standards that apply in each particular region. This standard is entitled Safety of machinery – General principles for design – Risk assessment and risk reduction. It gives a general overview and contains a guide to the major developments governing machines and...

Ball Transfer Units | General product information Product description / selection guide 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. Applications Conveyor systems ▶▶ Ball transfer tables, turntables and switches for sorting ▶▶ Feed tables for sheet-metal working machines ▶▶ Fixtures for press brakes ▶▶ Crossover sections of continuous conveyors ▶▶ Feed devices for machining centers ▶▶ Drilling machine tables and motor-driven...

Ball Transfer Units | General product information Technical data Structural design of the Ball Transfer Units A hardened ball cup serves as a raceway for a multitude of small supporting balls. The supporting balls roll against the ball cup when the load ball turns. Rexroth Ball Transfer Units are designed so that precise rolling and full load-bearing capability are ensured in any mounting orientation. Ball Transfer Units require little maintenance, and almost every type is protected against dirt by an oil-soaked felt seal. 1 Ball cup 2 Housing 4 Ball retaining ring 5 Supporting ring 6...

Ball Transfer Units | General product information Technical data Arrangement of the Ball How the Ball Transfer Units should be arranged depends on the undersurface of the conveyed Transfer Units article. For articles with a uniform, smooth undersurface, such as boxes and cases, the distance between the Ball Transfer Units is calculated simply by dividing the smallest edge length by 2.5. Example: Undersurface of the conveyed article = 500 x 1000 mm Distance between Ball Transfer Units To determine the load for a Ball Transfer Unit, the weight of the conveyed article is divided by 3. Ball...

These guideline values apply to any mounting orientation for rolling contact on a hardened steel plate. Operating temperature Ball Transfer Unit with steel load ball At temperatures above 100 °C, only bright metal load balls without a felt seal should be used. Make allowance for reduction in load capacity....
