Value Collection 1.19K1018ST-2 Round Linear Shaft

Product Description

The VALUE COLLECTION 1.19K1018ST-2 is a keyed round linear shaft machined from 1018 steel, designed for use in linear motion assemblies and mechanical drive systems. At 1.19 inches in diameter and 36 inches in overall length, this shaft provides a solid, dimensionally consistent component for applications that require a fixed keyway alignment feature. The 1/4-inch key size allows positive torque transfer between the shaft and mating components such as collars, sprockets, or hubs. It suits motion control builds in both industrial and light commercial settings where precise shaft positioning is essential.

This shaft is used in linear motion systems across a range of mechanical and industrial applications, including conveyor drives, actuator assemblies, and power transmission setups that rely on guided or keyed shaft arrangements. The 1018 steel construction provides adequate strength and machinability for standard duty motion control builds. It is a common replacement or new-build component for machine shops, maintenance technicians, and mechanical engineers working within the motion control and fluid power category.

Key Features

• Keyed shaft design with a 1/4-inch key size for positive torque transmission
• 1018 steel material grade offers good machinability and consistent mechanical properties
• 1.19-inch diameter conforms to 1-3/16-inch fractional sizing for standard bore components
• 36-inch overall length provides stock length suitable for cutting to custom sizes
• Round linear shaft profile compatible with standard linear bearings, bushings, and support rails

Compatibility

Designed as a standard-duty round linear shaft for use in motion control and power transmission assemblies requiring a 1-3/16-inch keyed shaft with a 1/4-inch key.

Installation Notes

Installation is typically performed by mechanical technicians or machinists as part of a motion control or drive assembly. De-energize all equipment and lock out power sources before removing or installing shafting. Ensure mating bores, bushings, and support blocks are sized and aligned to the 1.19-inch shaft diameter before assembly. Cut to length using appropriate metal cutting equipment if a shorter shaft is required, and deburr all cut ends before installation.
