Downward Mount Ball Transfer Unit SI-12Problems It Solves
- Loads that need to change direction at the end of a conveyor without a powered diverter
- Operators pushing heavy cartons, pallets or steel sheets across a fixed deck plate
- Transfer tables between two lines running at right angles to each other
- Decks in wet or washdown areas where a carbon steel unit would corrode
- Mixed product weights that require several load ratings on the same table
Who It Is For
- Conveyor builders designing transfer and rotation points into a line
- Sheet metal shops loading heavy blanks onto cutting and forming machines
- Material handling equipment makers building ball decks and transfer tables
- Industrial distributors stocking ball transfer units by load rating and mounting type
Why This Range
- Ten models across two mounting types: flange mount and downward mount
- Load capacity from 15 kg to 600 kg, with max load capacity and unit weight published for each
- Ball material is steel; case material available in steel with galvanizing, chrome plating, or stainless steel
- Flange mount units allow for removal and service, downward mount units offer compact installation
- All models share consistent load ratings and mounting styles for easier procurement and design
Application Scenarios
- Ball decks at the discharge end of a roller conveyor
- Transfer tables between two conveyor lines
- Sheet metal loading tables feeding a press brake or laser cutter
- Die change trolleys where a heavy tool is pushed sideways into position
- Assembly stations where a fixture is turned by hand between operations
SI SD Series Questions
How do I work out how many ball transfer units I need?
Divide the load by the number of units in contact with it and choose a model whose rated load capacity covers that figure, keeping peak loads under the maximum load capacity.
What is the difference between flange mount and downward mount?
Flange mount units are bolted to the deck through a flange and can be removed for service, while downward mount units are pressed into a hole in the deck and install faster.
Can I get stainless steel ball transfer units?
Yes, the case material can be supplied in stainless steel for wet and washdown areas.
Which ball material should I use on painted panels?
A steel ball is used where marking is not a concern; a nylon ball is not available in this series.
Do you publish the weight of each unit?
Yes, load capacity, maximum load capacity and unit weight are listed for each model.
Which series should I look at first?
Start from the load per unit, then choose the series that offers that rating in the mounting style your deck plate allows.
