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.

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.

High Quality Bearings
I have a Zeroturn PM260 from Gravely. It has a three spindle, 60inch mower deck. Each spindle has two of these bearings inside. These were a perfect match. They are sealed on both sides. You don't need the locking collar as the cores of the bearings are compressed together with a spacer in between inside the spindle. It took more time and effort to break loose the compression ring so the shaft can be pulled out and the bearings replaced. The bearings are nice and tight but spin smoothly. This quieted down the sound while running as the old bearings were pretty wore and loose. Timken makes very high quality transmission parts.
