Carbon Steel & Stainless Spanner Bushings | CasterHQ

Spanner Bushings for Casters and Wheels


Carbon steel and stainless spanner bushings from CasterHQ are essential components that provide added durability and stability to your caster assemblies.


Carbon steel and stainless spanner bushings are made from durable materials that can withstand heavy loads and constant use. These spanner bushings are designed to resist corrosion, abrasion, and wear, ensuring long-lasting performance even in harsh environments. By using these spanners, you can ensure the longevity of your caster assemblies, reducing the need for frequent replacements.


Spanner bushings provide stability and support to caster assemblies, particularly in heavy-duty applications. These spanner bushings help distribute the weight evenly and reduce axle deflection, ensuring smooth and stable operation even when carrying heavy loads. By using high-quality spanner bushings, you can maximize the load-bearing capacity of your casters and improve overall performance.


Spanner bushings help dampen noise and reduce vibration, making them suitable for applications where noise reduction is important, such as offices or healthcare facilities. The reduced vibration also contributes to a smoother and more comfortable rolling experience.


Using carbon steel and stainless spanner bushings from CasterHQ offers durability, stability, easy installation, versatility, and reduced noise and vibration. These factors contribute to the overall performance and longevity of your caster assemblies, ensuring smooth and reliable mobility in a variety of applications. Investing in high-quality spanner bushings is a worthwhile choice for anyone seeking to enhance the durability and performance of their caster assemblies. Our caster company offers the best customer service and support, so if you have questions, don't hesitate to ask. Shop these best spanner bushings online today!



To make it easier please use the chart below when ordering spanners for casters. All spanners are made to fit with a specific width/hub lengths of caster wheels. If you are needing a spanner to fit a wheel that is 2" wide there is only one spanner that will fit that wheels hub length. Same goes for 1-1/4" Wide Wheels, 2", 2-1/2" and 3" Wide Wheels. Follow the list below if it is caster related. If you plan on using the spanners aside from casters please disregard the list below.
