💡 How does operating speed affect load capacity in strut channel bearing trolleys?
Load ratings change with speed because bearing stress and heat increase as RPM goes up.

• Lower RPM allows higher safe working loads and better stability

• Keeping speeds under 300 RPM improves bearing life in overhead rails

• Higher speeds require reduced load to prevent bearing damage

• Sealed bearings help maintain quiet, wobble-free motion under load

This trolley set is a handy choice when you want quiet sliding, strong load support, and dependable performance for heavy duty handling without bulky hardware.
