Thomson Industries SB16 Shaft Support 1 Inch Plain Shaft

Product Description

The THOMSON INDUSTRIES SB16 is a plain-shaft support block designed to hold and align round linear shafting in motion control and mechanical drive systems. Constructed from malleable iron alloy, the SB16 provides a rigid, stable mounting base for 1-inch diameter shafting with a tight diameter tolerance of -0.001 to +0.001 inches. Center height is 1.5 inches, placing the shaft centerline at a fixed, predictable elevation above the mounting surface. This part is typically installed by mechanical technicians and automation or motion-system integrators working on linear actuator assemblies, conveyor frames, or industrial drive systems.

The SB16 is suited for use in industrial and commercial motion control applications where plain round shafting must be supported at fixed intervals to prevent deflection or misalignment. Common scenarios include linear slide assemblies, machine tool tables, and automated material handling equipment. The mounting footprint uses two bolts on a 2.5-inch center-to-center spacing, fitting standard mounting patterns common in Thomson-compatible linear systems.

Key Features

• Malleable iron alloy construction for rigidity and durability in industrial environments
• 1.5-inch center height provides fixed, consistent shaft elevation above mounting surface
• Two-bolt mounting pattern with 2.5-inch center-to-center hole spacing
• 0.28-inch mounting hole diameter accommodates standard fastener sizes
• Compact profile with 3.25-inch overall length and 2.56-inch overall height

Compatibility

Designed as an OEM-style shaft support for 1-inch diameter plain round linear shafting in industrial motion control and linear guide systems.

Installation Notes

Installation is typically performed by mechanical technicians or automation integrators. Ensure all power and motion to the machine is fully locked out and tagged out before removing or installing shaft support components. Mount to a flat, rigid surface using fasteners appropriate for the load; verify bolt torque against machine documentation. Confirm shaft alignment across all support points before returning the assembly to service.
