Part of the D Series range, used in Sheet Metal and Press Shops.
Key Benefits
- Carries 16 kg per unit in normal service and 20 kg at peak load
- Stud mount with M8 thread allows secure attachment to worktables without drilling a full hole
- Fine machined ball and seat reduce rolling resistance under light to moderate static load
- Nylon ball option protects painted or polished surfaces from marking
- Stainless steel ball and case option for use in wet or washdown environments
Application Scenarios
- Transfer points on a flat worktable where trays or small components need to be repositioned by hand
- Assembly line stations where a fixture must be rotated or aligned in any direction
- Feeding systems for packaging machinery requiring smooth, omnidirectional movement
- Processing machinery with curved work surfaces such as router tables or band saws
- Conveyor integration points where a flat load must be transferred between two lines
Who It Is For
- Conveyor system integrators building low-load transfer and alignment points
- Industrial equipment builders designing workstations with manual repositioning
- Packaging machinery manufacturers needing small omnidirectional transfer units
- Assembly line builders integrating manual alignment features into production lines
- Industrial distributors stocking ball transfer units by load rating and mounting type
Problems It Solves
- Flat loads that stick or drag when pushed across a fixed deck plate
- Workstations where product must be rotated or repositioned without powered alignment
- Operators struggling to move small loads by hand due to high friction or misalignment
- Need for a compact, fixed-mount ball transfer unit that does not require a recessed hole
- Requirement for a unit that can be easily replaced or maintained without removing the deck
Technical Features
- Fine machined ball and seat for consistent rolling under light static load
- Stud mount with M8 thread allows direct screwing into a worktable or deck plate
- 15.875 mm diameter ball provides a balance between load capacity and compact size
- Ball supplied in nylon, steel, or stainless steel to match surface protection needs
- Case supplied in steel or stainless steel for durability in dry or wet environments
- Overall dimensions of 24 mm diameter and 32.5 mm height for compact integration
Materials
- Nylon ball for non-marking contact with painted or polished surfaces
- Carbon steel ball and case for general industrial use in dry environments
- Stainless steel ball and case for wet, washdown, or corrosive conditions
Quality Control
- Load capacity verified against the 16 kg working load rating before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the ball and case option ordered
Customization Options
- Ball material selected between nylon, steel, and stainless steel
- Case material selected between steel and stainless steel
- Other D Series load ratings available where 16 kg is not the right size
Use Guide
- Divide the total load by the number of units in contact to ensure no unit exceeds 16 kg working load
- Keep peak and impact loading below the 20 kg maximum load figure
- Mount the unit on a flat, rigid surface so all balls sit at the same height
- Choose the nylon ball where the load surface must not be marked
- Choose stainless steel ball and case where the unit is exposed to moisture or cleaning agents

Machining of the case and ball seat to precise tolerances
Step 2
Assembly of the ball and support mechanism
Step 3
Drilling and threading of the stud mount for M8 attachment
Step 4
Final load check and visual inspection before packing
Compared With Other Options
| Flange mount ball transfer units | Stud mount screws directly into the deck, allowing easier removal and replacement than a flange that requires a bolted connection |
|---|---|
| Press fit ball transfer units | Stud mount provides a secure, removable attachment, while a press fit unit is faster to install but harder to service |
| Higher rated D Series units | The D-5HR is suited for 16 kg loads, so heavier applications require a larger unit with higher load capacity |
