These are replacement bearings for jack shaft housings and shafts that bolt on mower decks. These are much cheaper and much better bearings than factory replacements made in China. I pull both inside metal shields off before installing the bearings so the grease can reach the balls inside the races. Saved me lotsa money over having to replace complete jackshaft housings. Buying factory John Deere bearings are almost 3 times as much and are made in China. Nachi bearings say: Made in Japan.
CAME ON A TIMELY MANOR IN GOOD CONDITION
Got 2 of these for replacement motor bearings in a belt sander drive motor. They installed easily and are working fine --- it's like a new motor now! I've had good success in past repairs to various power tools with Nachi Bearings.
Thanks for the fast shipping. Amazing high quality for the best price.
Perfect fit, great customer responsiveness to get the right one. Very reasonable price.
