Thomson Industries A122026 Closed Linear Bearing 200 Lb

Product Description

The THOMSON INDUSTRIES A122026 is a closed-style linear ball bushing bearing designed for precision linear motion applications. It features a 0.75-inch bore diameter and a 1.25-inch outside diameter, with an overall length of 1.61 inches. The closed configuration provides a full complement of five ball circuits, delivering a dynamic load capacity of 200 pounds. This bearing is built from steel and uses a fixed alignment style with a round bore, making it suitable for demanding linear guide systems in industrial and mechanical assemblies. It is typically installed by maintenance technicians and mechanical engineers working with linear shaft and rail setups.

The A122026 is suited for use in linear motion systems where a compact, closed bearing housing is required. The closed design fully encloses the ball circuits, which helps retain lubrication and limit contamination ingress compared to open-style variants. With a bore diameter of 19.05 millimeters (0.75 inches) and five ball circuits, it provides higher load support than comparable open-style units, which are rated at 140 pounds dynamic load. Typical install scenarios include automated machinery, conveyor guides, actuator systems, and precision positioning equipment requiring repeatable, low-friction linear travel.

Key Features

• Closed bearing style with five ball circuits for maximum dynamic load support
• 200-pound dynamic load capacity in closed configuration
• 0.75-inch round bore with fixed alignment for stable shaft engagement
• Steel construction for durability in industrial environments
• Compact overall length of 1.61 inches suits space-constrained assemblies
• Retaining ring grooves allow secure axial positioning in housings

Compatibility

Designed as an OEM-style replacement or direct-fit closed linear ball bushing bearing for 0.75-inch diameter linear shafts in standard linear motion assemblies.

Installation Notes

Installation is typically performed by mechanical technicians familiar with linear motion systems. De-energize and lock out all power to the machine before servicing any bearing assembly. Press-fit or retaining-ring mounting should follow the housing manufacturer specifications to avoid damage to the bearing races or ball circuits. Do not apply impact directly to the bearing body during installation; use a proper bearing press or installation sleeve.
