Product Overview

The NL-38A is a flange mount ball transfer unit with a 38.1 mm diameter nylon, steel or stainless steel main ball, rated for 25 kg working load and 35 kg maximum load. It is designed for use on flat deck plates in material handling systems where light to medium loads must be moved and rotated in any direction by hand. The unit weighs 420 g and is supplied with a nylon case. It is suitable for integration into conveyor transfer points, feeding systems, and processing machinery auxiliary equipment.

Part of the NL Series range, used in Warehouse and Distribution Centres.

Key Benefits

  • Carries 25 kg per unit in normal service and 35 kg at peak load
  • Flange mount allows secure attachment to deck plates with two mounting screws
  • 38.1 mm diameter ball provides stable support for flat, smooth items like trays
  • Nylon case resists corrosion and reduces noise during operation
  • Omni-directional movement allows product rotation and repositioning without powered diverters

Application Scenarios

  • Transfer points between two conveyor lines running at right angles
  • Feeding stations in packaging machinery where trays need to be rotated
  • Processing tables where flat components are manually repositioned
  • Assembly line workstations requiring 360-degree load adjustment
  • Conveyor end points where operators rotate cartons or trays by hand

Who It Is For

  • Conveyor system integrators building transfer and rotation points
  • Material handling equipment builders designing feeding and processing tables
  • Industrial distributors stocking ball transfer units by load rating
  • Assembly line and production line builders needing manual repositioning
  • Packaging machinery manufacturers requiring omni-directional movement

Problems It Solves

  • Loads that jam or bind when pushed across a fixed deck plate
  • Transfer points where product must change direction without powered components
  • Manual repositioning that requires excessive force due to high rolling resistance
  • Inconsistent load handling when using multiple uncoordinated components
  • Need for a single supplier to provide matching ball, case and mounting features

Technical Features

  • 38.1 mm diameter main ball for consistent contact with flat surfaces
  • Flange mount with two screw holes for secure attachment to deck plates
  • Nylon case provides corrosion resistance and low noise operation
  • Main ball available in nylon, steel or stainless steel to match load surface
  • Unit weight of 420 g for deck load and shipping calculations

Materials

  • Nylon ball for non-marking contact with painted or polished surfaces
  • Carbon steel ball for general industrial use with higher wear resistance
  • Stainless steel ball (SUS304) for wet, washdown or corrosive environments
  • Nylon case for resistance to moisture and chemical exposure
  • Steel case not available; only nylon case supplied

Quality Control

  • Load capacity verified against the 25 kg working load before packing
  • Ball rotation checked by hand for free movement in all directions
  • Material grade confirmed against the ball and case option ordered
  • Flange alignment checked to ensure even mounting on deck plates
  • Weight verified at 420 g for shipping and deck load calculations

Customization Options

  • Ball material selected between nylon, steel and stainless steel
  • Case material is fixed as nylon; no steel case option available
  • Other NL Series load ratings available where 25 kg is not the right size
  • Mounting hole pattern and flange diameter are standard for this model

Use Guide

  • Divide the total load by the number of units in contact to ensure no more than 25 kg per unit
  • Keep peak and impact loading below the 35 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 where the deck is washed down or exposed to moisture

Final inspection and packing

Compared With Other Options

Press fit ball transfer unitsFlange mount allows removal and replacement without damaging the deck, while press fit units are faster to install but harder to service
Lower rated NL Series unitsThe NL-38A suits 25 kg loads, so lighter applications are better served by a smaller unit with lower rolling resistance
Plain rollersBall transfer units allow movement in any direction, while rollers only move product along one axis

POM Ball Transfer Unit NL-38A Questions

What load can one NL-38A ball transfer unit carry?

The rated load capacity is 25 kg per unit and the maximum load capacity is 35 kg.

How is the NL-38A mounted?

It is a flange mount unit, so it is bolted through the flange onto the deck plate using two screws.

Which ball material should I choose?

Nylon for surfaces that must not be marked, carbon steel for general use, and stainless steel for wet or washdown areas.

Is a stainless steel version available?

Yes, the main ball can be supplied in stainless steel (SUS304).

How much does the unit weigh?

Each NL-38A weighs 420 g, which is used for deck load and shipping calculations.

Can I get other load ratings in the same series?

Yes, the NL Series includes other load ratings, so ask for the model that matches your load per unit.
