Aluminum Shaft End Support Blocks

Shaft support end blocks are mounting components used to hold the ends of round linear shafting in place, keeping the shaft aligned and helping reduce deflection under load. In a linear motion system, they provide a stable bolt-down support point for the shaft so bearings, carriages, or other moving components can travel smoothly along the supported axis. PBC Linear NSB Series aluminum linear shaft end support blocks are precision-machined for lightweight, durable shaft support in automation, robotics, and precision motion applications. Pre-drilled mounting holes allow fast bolt-down installation, while the aluminum construction provides a strong, corrosion-resistant support structure without adding unnecessary weight. These shaft support blocks work with multiple shaft types, including case-hardened steel, stainless steel, and ceramic-coated aluminum shafting. Available in inch sizes from 1/4 in to 2 in and metric sizes from 8mm to 50mm, the NSB Series provides versatile end or intermittent shaft support for a wide range of linear bearing and linear guide systems. Metric options are also available in a round flanged mount style for additional mounting flexibility.
