Thomson Industries A243848 Closed Linear Bearing 770 Lb

Product Description

The THOMSON INDUSTRIES A243848 is a closed-style ball bushing linear bearing designed for precision linear motion applications in industrial machinery and automation equipment. With a 1.5-inch bore diameter and a 2.375-inch outside diameter, this bearing supports a dynamic load capacity of 770 pounds in the closed configuration. The closed design uses 6 ball circuits to fully enclose the shaft, providing load support and contamination resistance in demanding environments. Mechanical technicians and machine builders install this bearing in linear actuators, slide assemblies, and motion-control systems where consistent, low-friction travel is required.

This bearing is suited for fixed-alignment linear motion installations in both industrial and commercial equipment. Its round bore and fixed alignment style make it compatible with standard linear shafting setups. The closed configuration is preferred when the application demands load capacity in all radial directions or when the installation environment exposes the bearing to particulate contamination. It fits into housings and pillow blocks designed for 1.5-inch bore linear bearings with a 2.375-inch OD and an overall length of approximately 2.98 inches.

Key Features

• Closed bearing style with 6 ball circuits for full 360-degree radial load support
• Dynamic load capacity of 770 pounds in closed configuration
• 1.5-inch bore diameter with round bore for standard linear shaft compatibility
• 2.375-inch outside diameter for use in standard linear bearing housings
• Fixed alignment style suited to rigid, precision-aligned linear guide systems
• Steel construction for durability in demanding mechanical environments

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial linear motion systems requiring a closed ball bushing bearing with a 1.5-inch bore, 2.375-inch outside diameter, and approximately 2.98-inch overall length.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with linear motion systems. Ensure the mating linear shaft and housing bore are clean, properly aligned, and free of burrs before pressing or sliding the bearing into position. De-energize and lock out all power sources before servicing any equipment containing this bearing. Avoid applying direct impact to the bearing races during installation; use a bearing press or appropriate installation tool to seat the component evenly.
