SI SD Series Ball Transfer Units
SI and SD units are the stainless-bodied machined range built for hygiene-critical and corrosive environments, where both the housing and the ball have to survive daily cleaning without plating to lose.

Plated carbon steel units in a wash-down bay fail from the inside: water sits in the support ball bed, rust forms under the plating and the ball stiffens long before the outside looks bad.
How to choose
Stainless is specified for the environment, not the load; where both high load and corrosion resistance are needed, check the rating of the stainless model against the equivalent carbon steel unit, which is normally higher.
Typical applications
- Meat, dairy and beverage packing lines
- Chemical and pharmaceutical handling benches
- Marine and coastal installations
- Outdoor transfer plates exposed to rain

Frequently Asked Questions
Which stainless grade is used?
Stainless models are commonly supplied in SUS304; the exact grade for a given model is confirmed on the drawing.
Can stainless units be steam cleaned?
They tolerate wash-down. Steam and aggressive chemicals should be confirmed against the seal and support ball materials for the specific model.
