Drawing-Based Quality Requirements
- Swivel rotation should be smooth, without dead spots or abnormal noise.
- The upper cover should remain secure without looseness.
- For the single-caster vertical-play test, measure at a point extending 200 mm outward from the center of the upper cover.
- Vertical movement during the specified test should not exceed 2 mm.
- Lubrication points should use No. 3 / No. 2 grease as specified in the drawing.
Applications
The 125 mm red industrial nylon wheel is intended for industrial carts, trolley assemblies and mobile equipment that require a compact swivel caster. The PA6 nylon wheel provides a rigid running surface, while the metal swivel bracket supports directional rotation. Buyers should confirm the load per caster, floor type, turning frequency, daily operating cycle and mounting structure before ordering. The working environment should also be reviewed when the caster is exposed to water, dust, cleaning agents or outdoor conditions. The Ø19.5–20.5 mm top mounting interface must match the equipment assembly.
Customization Options
Custom 125 mm industrial nylon wheels can be reviewed according to a 2D drawing, 3D model or physical sample. Buyers can specify the PA6 wheel diameter, wheel width, color, top mounting interface, caster offset, overall height, swivel bracket geometry, dimensional tolerance and packaging method. For an accurate quotation, please provide the cart type, load per caster, floor condition, indoor or outdoor use, turning frequency, required quantity and estimated annual volume. Material selection and tooling requirements depend on the product structure and application conditions.

FAQ
What is the diameter of this red industrial nylon wheel?
The nominal wheel diameter is 125 mm, which is approximately 5 inches. The complete swivel caster has an overall height of 155 ±1.0 mm. Wheel width is available upon request and should be confirmed according to the required cart or trolley assembly.
What material is used for the wheel?
The wheel is made of PA6 nylon. The supplied drawing also specifies a cold-rolled steel swivel bracket, cold-rolled steel upper and lower covers, PP cover plates and a PE steel-ball retainer. The required color for this product is red.
What are the mounting dimensions?
The drawing specifies a Ø19.5–20.5 mm top mounting interface, a 40 mm caster offset with a tolerance of +0.5 / -1.0 mm and a 96 mm height from the upper mounting surface to the wheel axle centerline.
What quality checks are specified for the swivel caster?
The caster should rotate smoothly without dead spots or abnormal noise. The cover should remain secure. During the specified vertical-play test, movement should not exceed 2 mm when measured at a point extending 200 mm outward from the center of the upper cover.
Can the color and mounting structure be customized?
Yes. Custom wheel colors, mounting interfaces, caster offsets, bracket structures and dimensional tolerances can be reviewed according to your 2D drawing, 3D model or physical sample. Tooling cost depends on the drawing and product structure.
Are samples available for testing?
Sample availability depends on the required wheel dimensions, PA6 material requirements, mounting interface, bracket structure, tooling status and quantity. Please provide your technical drawing or physical sample so that the specification can be reviewed before sample preparation.
