Product Overview

The NL-38B is a flange mount ball transfer unit with a 38.1 mm diameter nylon main ball, rated for 25 kg working load and 35 kg maximum load. It is constructed with a nylon case and bolts through a flange onto a deck plate, allowing smooth 360-degree movement of flat, smooth objects such as trays. The unit weighs 410 g and is designed for integration into conveyor systems, feeding lines, and processing machinery where directional flexibility is required.

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 and easy removal for maintenance
  • Nylon case resists corrosion and reduces noise during operation
  • 38.1 mm diameter ball enables smooth rolling of flat, rigid items
  • 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 on packaging or processing machinery where trays need to be rotated
  • Assembly line workstations where a fixture must be turned by hand
  • Loading tables for flat components entering a press or laser cutter
  • Conveyor decks where product alignment is adjusted manually before processing

Who It Is For

  • Conveyor system integrators building transfer and rotation points
  • Material handling equipment builders designing feeding and processing lines
  • Industrial distributors stocking ball transfer units by load and size
  • Assembly line builders requiring manual repositioning of fixtures
  • Packaging machinery builders needing omni-directional movement for trays

Problems It Solves

  • Product jams when pushed across a fixed deck due to lack of directional flexibility
  • Need to reposition flat items like trays without using powered turntables
  • Operators struggling to rotate heavy or rigid loads at the end of a line
  • Inconsistent performance when using multiple small rollers or casters
  • Difficulty in aligning items on a deck where movement must occur in any direction

Technical Features

  • 38.1 mm diameter main ball for stable rolling of flat, smooth surfaces
  • Flange mount with two screw holes for secure attachment to deck plates
  • Nylon case provides lightweight construction and resistance to moisture
  • Main ball available in nylon, steel, or stainless steel to match surface requirements
  • Unit weight of 410 g for deck load and shipping calculations

Materials

  • Nylon case for lightweight, corrosion-resistant use in dry or mildly humid environments
  • Nylon ball for non-marking contact with painted or polished surfaces
  • Steel ball for higher wear resistance under repeated load
  • Stainless steel ball (SUS304) for wet, washdown, or corrosive conditions

Quality Control

  • Load capacity verified against the 25 kg working rating before packing
  • Ball rotation checked by hand for free movement in all directions
  • Material grade confirmed against the ball and case option ordered
  • Flange and mounting holes inspected for correct alignment and finish

Customization Options

  • Ball material selected between nylon, steel, and stainless steel
  • Case material available in nylon for standard use
  • Other NL Series load ratings available for different load requirements

Use Guide

  • Divide the load by the number of units in contact to ensure no unit exceeds 25 kg working load
  • 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
  • Use stainless steel ball and case where the deck is exposed to washdown or moisture

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-38B suits 25 kg loads, so lighter applications are better served by a smaller unit with less rolling resistance
Standard casters or rollersBall transfer units allow movement in any direction, while casters and rollers only move product along a single axis

POM Ball Transfer Unit NL-38B Questions

What load can one NL-38B 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-38B mounted?

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

Which ball material should I choose?

Nylon for non-marking contact, steel for higher wear resistance, stainless steel for wet or corrosive environments.

Is a stainless steel version available?

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

How much does the unit weigh?

Each NL-38B weighs 410 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.
