The CHICAGO PNEUMATIC c120326 is a replacement ball bearing designed for use in Chicago Pneumatic power tools and pneumatic equipment. Ball bearings of this type support rotating shafts and spindles, reducing friction and handling radial and axial loads during tool operation. This component is a direct OEM-style replacement part intended for service technicians and tool repair professionals who maintain or rebuild Chicago Pneumatic equipment. Proper bearing condition is critical to tool performance, service life, and operator safety.
This bearing is used in the repair and maintenance of Chicago Pneumatic power tools and accessories. It is typically installed during scheduled service intervals or when worn, noisy, or seized bearings are identified during inspection. Tool repair technicians working on pneumatic grinders, impact wrenches, drills, and similar equipment will encounter bearing replacements as a routine part of the rebuild process.
Designed as an OEM-style replacement bearing for Chicago Pneumatic power tools and accessories. Verify fitment against your specific tool model and service documentation before installation.
Bearing replacement should be performed by a qualified tool repair technician familiar with pneumatic tool disassembly procedures. Disconnect and depressurize the tool from its air supply before beginning any service work. Use a bearing press or appropriate driver to seat the bearing squarely without applying force to the rolling elements. Refer to the Chicago Pneumatic service manual for your specific tool model to confirm correct bearing orientation and assembly sequence.
