Thomson Industries OPN101824 Open Linear Bearing

Product Description

The THOMSON INDUSTRIES OPN101824 is an open-style linear ball bushing bearing designed for use in linear motion systems requiring a fixed-alignment, round-bore configuration. With a 0.625-inch inside diameter and a 1.125-inch outside diameter, this bearing fits standard shaft sizes used across industrial and light commercial machinery. The open design exposes one side of the bearing, allowing it to travel along a shaft that has an obstruction or guide rail on one side. Dynamic load capacity reaches 150 pounds in the closed position, with an open dynamic load capacity of 105 pounds. At 0.15 pounds, this is a compact unit suited for precision linear assemblies.

This bearing is commonly installed in linear actuators, slide assemblies, CNC guide systems, and automated equipment where a shaft runs through a carriage or support block. The open configuration makes it practical for applications where the shaft cannot be fully enclosed, such as gantry systems, pick-and-place rigs, and pneumatic slide tables. It is typically specified by mechanical designers and installed by maintenance machinists or automation technicians during machine build or component replacement.

Key Features

• Open bearing style allows travel along partially obstructed or rail-mounted shafts
• 0.625-inch bore diameter fits standard fractional linear shafts
• 150-pound closed dynamic load capacity and 105-pound open dynamic load capacity
• 3 ball circuits in open configuration; 4 ball circuits in closed configuration
• Steel construction for durability in industrial linear motion applications
• Fixed alignment style for consistent, predictable shaft engagement

Compatibility

Designed as an OEM-style replacement or direct-fit component for linear motion assemblies that use a 0.625-inch round-bore open linear ball bushing with a 1.125-inch outside diameter and 1.485-inch overall length.

Installation Notes

Installation of linear ball bushings should be performed by a qualified mechanical technician or machinist. Power down and de-energize all actuators and motion systems before removing or installing any bearing components. Press-fit installation requires a properly sized arbor press to avoid damaging the ball retainer or bore surface - do not hammer directly on the bearing body. Verify shaft diameter and housing bore tolerances against manufacturer specifications before assembly.
