Nylon Fixed Castors

Wheels and castors are essential components in internal transport systems. Whenever precise, stable straight-line tracking is crucial, fixed castors are the right choice: they reliably guide trolleys, equipment, or systems in one direction and prevent unwanted lateral movement

This page provides a clear guide to when Nylon fixed castors are useful, what types are available, and what you should consider when choosing them – from load capacity to bearings

What are fixed castors – and what is the difference between them and Swivel castors?

Fixed castors are stationary. They cannot swivel and only move in a straight line. Swivel castors are rotatable and allow changes of direction. In practice, both are often combined: swivel castors for manoeuvring, fixed castors for stability and tracking.

Nylon fixed castors: When are Nylon fixed castors the right choice?

< Nylon fixed castors are often used when a smooth, durable castor is required, and the castor needs to remain dimensionally stable under load. Typical applications include warehouses, workshops, manufacturing, and assembly – anywhere trolleys and racks need to reliably cover repetitive routes

  • True straight-line tracking: stable on defined routes
  • Robust for everyday use: Suitable for many standard industrial applications
  • Variety of options: different diameters, wheel widths, heights and bearings
 

Material & Series: Polyamide (PA6) – e.g. B. KN series

WICKE offers wheels from the KN series. as injection-moulded Nylon wheels made of high-quality polyamide PA6 Available in natural/white colour. Depending on the model, the wheels optionally with plain, roller or deep groove ball bearings Available. According to the product information, polyamide 6 is suitable for temperatures of -40°C to 90°C usable (depending on product/series)

 

Housing & Mounting: What matters in practice

For assembly, the following are particularly important: Base plate , Hole spacing and hole diameter Crucial. Ensure that the drilling pattern of your design matches the castor model so that installation is successful without rework

Example from the WICKE product range: Fixed forks with plate mounting Series B are made from reinforced pressed sheet steel and then galvanized The series is designed for manually moved load capacities up to 500 kg (depending on the version).

Selection guide: How to find the right Nylon fixed castors

1) Calculate load-bearing capacity correctly

Determine the total weight of the trolley/frame plus its maximum payload. Divide this value by the number of castors and include a safety margin (e.g., for floor irregularities, steps, or uneven load distribution)

2) Diameter, wheel width, overall height

Larger diameters often improve rolling resistance. Wheel width and height affect the stability and installation height of your structure.

3) Bearings suitable for use

  • Plain bearings: Robust standard solution
  • roller bearing:  good compromise between load capacity and running
  • Deep groove ball bearings: very smooth operation even with frequent movements

4) Consider the operating environment

Surface Conditions, temperature range, and dirt ingress directly influence running characteristics and service life. For recurring applications, a well-designed wheel, bearing, and housing is recommended

Typical areas of application

  • Transport and order picking trolleys in warehouse & shipping
  • Assembly and tool trolleys in manufacturing & workshop
  • Machine and aggregate frames with defined travel path
  • Mobile shelving and material supply in the production environment
 

FAQ

What is the advantage of fixed castors over swivel castors?

Fixed castors ensure straight-line stability and tracking. Swivel castors are ideal for manoeuvring. Their combination results in controllable handling.

What type of bearings is advisable?

For robust standard applications, a plain bearing is often sufficient. For frequent movement or when smoother running is desired, (grooved) ball bearings are often more suitable – depending on the load, travel distances, and application profile.
