What Is A Ball Transfer Unit

A Ball Transfer Unit is an omnidirectional load-bearing sphere housed in a metal fixture. It works like an inverted ball caster, supporting smooth 360-degree movement. Objects placed on top can be pushed, pulled, or rotated easily with minimal friction. This design makes ball transfer units ideal for conveyor systems, material handling, and automated equipment.

Product Range

Popular Models of Stainless Steel Ball Transfer Units

Our ss ball transfer units are available in various types to meet diverse load, space, and environmental requirements. From compact designs for tight installations to heavy-duty models for high-impact handling, we offer solutions that ensure smooth, multi-directional movement in any setting.

All Stainless Steel Type

Body, housing, and ball are all made of stainless steel (304/316), ideal for food processing, pharmaceutical, chemical, or marine environments.

Stainless Steel Ball with Carbon Steel Housing

Cost-effective option for general industrial use, offering basic corrosion resistance.

Heavy Duty Ball Transfer

Reinforced for heavy loads and impact applications such as mold handling or aircraft tooling.

Spring Loaded Ball Transfer Unit

Built-in spring offers shock absorption or return action, used for positioning or buffering.

Miniature Ball Transfer Units

Designed for tight spaces or cleanroom environments, often used in electronics or precision handling.

Embedded / Recessed Mount Type

Space-saving design mounted flush with surfaces, ideal for integration into automation systems.

Flange Mounted Ball Transfer

Easy to bolt down; commonly used on heavy-duty bases or modular conveyors.

Low Profile Ball Transfer

Compact height allows use in restricted spaces while maintaining smooth movement.

Material Specification

Choosing the Right Grade

304 Stainless

Standard grade for indoor machinery, automation, and dry or mildly humid environments. Good resistance to cleaning chemicals. Cost-effective for high-volume orders. Not suitable for continuous salt spray or chloride-heavy process environments.

Food · Automation · Indoor

316 / 316L

Marine and food-grade standard. 2–3% molybdenum addition raises chloride pitting resistance significantly above 304. Required for outdoor, marine, offshore, and food equipment with CIP chemical cleaning. Especially 316 stainless steel has excellent resistance to corrosive saltwater effects.

Marine · Chemical · Pumps

17-4PH

Precipitation-hardened martensitic grade. ≥ 1,310 MPa tensile strength in H900 condition — significantly stronger than 316 at equivalent cross-section. Specified for ball joints in motorsport, aerospace, and high-cycle fatigue applications where load ratings are the primary constraint.

Optimizing Ball Transfers to Prevent Premature Failures

Failures of ball transfer units (BTUs) often result from underestimating point loads, duty cycles, and exposure to contamination. Lightweight housings can deform under concentrated loads, causing uneven ball rotation and increased friction. Insufficient internal ball support accelerates wear and eventually leads to jamming. Profab Machine addresses these issues by manufacturing BTUs based on actual operating conditions. We manage real load paths by adjusting ball diameters, internal support layouts, and housing thickness.
