Product Overview
The SP-8 is a press mount machined ball transfer unit with a 8 kg working load and 15 kg maximum load. It is designed to be pressed into a hole in a deck plate so that a light tray, panel or flat object can be moved and rotated in any direction by hand.

Key Benefits
- Carries 8 kg per unit in normal service and 15 kg at peak load
- Press mount fits into a drilled hole so the unit is fixed without bolts
- Fine machined ball seat keeps rolling effort low under light static load
- Stainless steel ball and case option for wet or washdown environments
- Nylon ball option protects painted or polished surfaces from marking
Application Scenarios
- Transfer points between two conveyor lines where light trays need to change direction
- Assembly stations where a small panel is rotated by hand between operations
- Feeding systems for packaging machinery handling flat, smooth components
- Processing tables where a light fixture or tool is repositioned manually
- Curved work surfaces on band saws or router tables requiring omnidirectional movement
Who It Is For
- Conveyor system integrators building low-load transfer points
- Material handling equipment builders designing light-duty transfer decks
- Industrial distributors stocking ball transfer units by load rating
- Packaging machinery manufacturers needing small omnidirectional transfer points
Problems It Solves
- Light loads that stick or drag when pushed across a fixed deck plate
- Transfer points where product must change direction without powered diverters
- Operators struggling to rotate a light load by hand at the end of a line
- Mixed decks where a single unit must handle both light and medium items
Technical Features
- Fine machined ball and seat rather than a pressed or stamped housing
- Press mount design fits into a drilled hole in the deck plate
- Main ball supplied in steel, stainless steel or nylon to suit the load surface
- Case supplied in steel, galvanized steel, chrome plated steel or stainless steel
- Unit weight of 15 g for deck load and shipping calculations
Materials
- Steel ball and case for general industrial use
- Stainless steel ball and case for wet or washdown environments
- Nylon ball for non marking contact with painted or polished surfaces
Quality Control
- Load capacity checked against the 8 kg 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 steel, stainless steel and nylon
- Case material selected between steel, galvanized steel, chrome plated steel and stainless steel
- Other SP Series load ratings available where 8 kg is not the right size
Use Guide
- Divide the load by the number of units in contact to check the 8 kg per unit rating
- Keep peak and impact loading below the 15 kg maximum load figure
- Mount units on a flat deck plate 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 deck is washed down

Compared With Other Options
| Flange mount ball transfer units | Press mount units are faster to install but harder to remove for service, while flange mount units are bolted and can be replaced |
|---|---|
| Higher rated SP Series units | The SP-8 suits 8 kg loads, so heavier decks are better served by a larger unit that rolls with less effort |
| Plain conveyor rollers | Ball transfer units allow movement in any direction, while rollers only move product along one axis |
