Based on my observations, these caster bearings are an excellent choice for anyone who needs reliable EQUIPMENT in their workplace... They are very sturdy easy to install, and provide a smooth ride even when carrying heavy loads. Additionally, the bearings are very durable and have a long lifespan compared to other casters in the same category. However, the only downside is that they might be a bit too expensive for some budget-conscious buyers. Overall, i highly recommend these caster bearings See full review
