Review: Fits gravely 152z model # 991030 - Bought 2 bearings to replace the worn out ones in a spindle for my mower. Saved over a $100 replacing the bearings compared to buying a new spindle. Will see how long it lasts.
Review: MADE IN CHINA - Hoped to buy quality USA bearing, but these Timken Bearings are made in China. Four stars is arbitrary- hoping they are still quality bearings.
