Boston Gear 18810 Thrust Bearing Washer Steel 1/4 in Id

Product Description

The BOSTON GEAR 18810 is a steel thrust bearing washer designed to handle axial loads in rotating shaft assemblies. With a 0.25-inch inside diameter, 0.5-inch outside diameter, and a thickness of 0.094 inches (3/32 inch), this washer-style thrust bearing provides a low-profile solution for absorbing thrust forces between mating components. It is suited for use in gearboxes, drive shafts, and mechanical power transmission equipment where axial load management is required. Machinists, millwrights, and mechanical assembly technicians typically specify and install this type of component.

This thrust bearing washer is used in light-duty axial load applications across industrial machinery, conveyor systems, and mechanical drives. Its compact washer-style profile makes it appropriate for installations with tight clearances where a full thrust bearing assembly is not required. The steel construction provides durability under moderate load and speed conditions typical of industrial power transmission environments.

Key Features

• Washer-style thrust bearing for axial load handling in rotating assemblies
• 0.25-inch inside diameter fits standard quarter-inch shafts
• 0.5-inch outside diameter for a compact footprint
• 0.094-inch (3/32-inch) thickness suits tight axial clearance applications
• Steel construction for durability in industrial power transmission use
• Single-piece washer design simplifies installation and replacement

Compatibility

Designed as an OEM-style replacement or service part for mechanical assemblies requiring a washer-style thrust bearing with a 0.25-inch bore, 0.5-inch outside diameter, and 0.094-inch thickness.

Installation Notes

Installation is typically performed by millwrights or mechanical technicians during gearbox service or shaft assembly work. De-energize and lock out all power to the equipment before removing or installing thrust bearing components. Ensure mating surfaces are clean and free of burrs to achieve proper seating and load distribution. Do not reuse worn or deformed washers, as uneven contact surfaces will reduce axial load capacity.
