Key Benefits

  • Carries 12 kg per unit in normal service and 15 kg at peak load
  • Screw mount provides a secure, removable attachment to worktables and benches
  • 15.875 mm diameter ball allows smooth movement of flat, smooth objects
  • Nylon ball option protects painted or polished surfaces from marking
  • Stainless steel ball and case option for use in wet or corrosive environments

Application Scenarios

  • Transfer points on a flat worktable where trays or flat components need to be repositioned
  • Assembly lines where a fixture must be rotated or aligned by hand
  • Packaging machinery where flat items are moved between stations
  • Processing systems requiring 360-degree movement of a flat load
  • Feeding systems where a flat object is guided into a machine by hand

Who It Is For

  • Conveyor system integrators building manual transfer points
  • Industrial equipment builders integrating ball transfer units into workbenches
  • Assembly line designers needing manual repositioning of fixtures
  • Material handling equipment makers building modular workstations
  • Industrial distributors stocking small load ball transfer units by model

Problems It Solves

  • Flat loads that stick or drag when pushed across a fixed surface
  • Manual repositioning points where product must change direction without powered guidance
  • Worktables where a fixture must be turned or aligned by hand without resistance
  • Systems requiring a low-profile, fixed ball transfer unit with secure mounting
  • Applications where surface marking from steel balls must be avoided

Technical Features

  • 15.875 mm diameter ball allows consistent contact with flat surfaces
  • Two screw holes in the housing for secure, adjustable mounting
  • Screw mount design allows removal and replacement without damaging the deck
  • Fine machined ball seat ensures smooth rotation under load
  • Compact size with M30 x 60 mm overall dimensions for space-constrained setups

Materials

  • Nylon ball for non-marking contact with painted or polished surfaces
  • Carbon steel ball and case for general industrial use
  • Stainless steel ball and case (SUS304) for wet, washdown or corrosive environments

Quality Control

  • Load capacity verified against the 12 kg rating before packing
  • Ball rotation tested by hand for free movement in all directions
  • Material grade confirmed against the ball and case option ordered
  • Mounting holes checked for correct M30 thread size and alignment

Customization Options

  • Ball material selected between nylon, steel and stainless steel
  • Case material selected between steel and stainless steel
  • Other models in the NJ LW FB Series available for different load or mounting requirements

Use Guide

  • Ensure the load is distributed evenly across the ball surface to avoid exceeding the 12 kg working load
  • Keep peak and impact loading below the 15 kg maximum load figure
  • Mount the unit on a flat, rigid surface so all balls sit at the same height
  • Use the nylon ball where the load surface must not be marked
  • Use stainless steel ball and case where the unit is exposed to moisture or cleaning agents

Compared With Other Options

Press mount ball transfer unitsScrew mount allows secure attachment and easy removal, while press fit units are faster to install but harder to replace
Higher load rated unitsThe LW-16 is suited for 12 kg loads, so heavier applications require a larger model with higher capacity
Swivel castersScrew mount ball transfer units are fixed to a surface and do not roll on the floor, unlike casters used for mobile equipment

Screw Mount Ball Transfer Unit LW-16 Questions

What load can one LW-16 ball transfer unit carry?

The rated load capacity is 12 kg per unit and the maximum load capacity is 15 kg.

How is the LW-16 mounted?
