Product Description

The TORO 138-9770 is a ball bearing designed as a replacement component for Toro outdoor power equipment and lawn and garden machinery. Ball bearings reduce rotational friction and support radial and axial loads in spinning assemblies such as spindles, wheels, and drive shafts. This part is installed by experienced technicians and equipment service professionals performing routine maintenance or component-level repairs on Toro-branded equipment.

This bearing is used in lawn and garden applications where Toro equipment requires an OEM-specification replacement bearing. Typical installation scenarios include spindle assembly rebuilds, wheel hub service, and drivetrain component replacement on Toro mowers and outdoor power equipment. Service personnel should verify fitment against the equipment model and serial number before ordering.
