REELY KBRM05 M4 plastový kĺbový klb s vnútorným závitom, igubal®, M4, 5 mm vŕtanie, bezúdržbový

In light-duty mechanical linkages, control rods, and automated fixtures, the REELY KBRM05 M4 plastic rod end bearing provides a corrosion-resistant, self-lubricating pivot point. Its igubal® design uses high-performance polymers for both housing and spherical ball, eliminating the need for external lubrication and withstanding humid or washdown environments.

Why choose it

The all-plastic construction eliminates metal-to-metal contact, reducing noise and wear while providing excellent resistance to corrosion and chemicals. The maintenance-free design lowers downtime and total cost of ownership in applications where regular lubrication is impractical.

Ideal use cases

• Light to medium load linkages in packaging, textile, and food machinery
• Corrosive environments such as marine, chemical, or outdoor equipment
• Applications requiring low friction and no lubrication
• Prototyping and custom mechanical assemblies

Good to know

The KBRM05 M4 is part of the igubal® KBRM series, known for dimensional interchangeability with many standard metal rod ends. Its M4 internal thread allows direct attachment to threaded rods or bolts.
