Nsk Bearings (2 Pack) 6203-2RS 6203DDU 6203VV Bearings 17X40X12MM Pressed Steel Cage,Deep Groove Ball Bearings

Fit perfectly in my 2013 Pentair Superflow model 348024 pump with 1.5 HP Century motor part number 196233. Took several days of internet searching, phone calls to both Pentair& Century was given incorrect information that's why I am posting this level of detail hopefully this helps someone else. BTW - INYOPOOL.COM was the only company with the correct information as some motors even use 2 different bearings - the correct bearings for this model 196233 Century motor are a pair (one on front & one on the rear of motor shaft) bearing part is 6203-2RS - I purchased the NSK brand which included 2 (a pair) of these bearings for about half the price of anywhere else $16 for both.I also purchased a set of 4 different size bearing pullers on Amazon for about $34 - excellent price.A hint to install new bearings 99% of instructional YouTube videos tell u to "hammer" them onto shaft using a steel pipe and rubber mallet while holding motor shaft assembly in a table vise. THIS IS A GREAT WAY TO DAMAGE/DESTROY NEW BEARINGS. Either they will fail immediately or within a short period of time, if u manage to hit pipe perfectly on inner ring of bearings it may not get damaged. THE FAR EASIER & SAFER METHOD is simple - turn on your oven set @115°C or 239°F, put new bearings on a cookie sheet or any small ovenproof pan with low sides for easy removal. I preheated oven & let bearings heat for about 15 minutes. My pump was in the yard 75' from oven in kitchen. I cleaned motor shaft using strips of 150-200 grit Emery cloth for metal to remove any rust, pitting and dirt stains, cleaned off residue with damp paper towel. After 15 minutes in oven grabbed pan with bearings using a pair of oven mitts and picked up one bearing at a time, slipped onto shaft like "butter" waited 20 seconds turned over to other side slipped on second bearing. Almost as soon as bearing is seated at bottom of shaft (lip) it expands as it cools and is firmly in place waiting 20 seconds may be overkill as the shaft itself is at ambient temperature and contains a lot more mass than the bearing so it absorbs the heat & cools down bearings in seconds. Both bearings after slip on installation- NO HAMMERING - spun freely, no damage to bearings, bearing plastic covers & no leakage of packing grease. Easy, safe way to install.

Worked out great for DIY upgrades to my cheapo mini metal lathe

48X inch (030001 - ) - ST541210 Though not shown on this drawing, these are the bearings for the Engine to deck drive pulleys. Not shown in the breakdown of this deck BUT sourced from the actual 6203DDU bearing shields. I guess JD would rather you buy 2 from them at the rather substantial price. I think I bought the two exposed pulleys and these bearings for the price for the one pulley (sheeve). Also, when replacing spindle bearaings, remove the inner shield for top and bottom bearing so that all that grease you were pumping into the shafts can actually get into your spindle bearings and you'll probably never have to replace them again. NOT necesarily JD's fault. ALL the spindle shafts of all the mowers (and they look to be from the same supplier) had that trick in there.

I replaced bearing on belt tensioner pulley, so far so good.

What I don’t like is the fact that when you search for a specific part number, Amazon will show you many other items. You have to be attentive or you will end up buying something you didn’t search for as I did. Still good bearings. Check numbers closely before clicking to buy.

Working on a 97 Mitsubishi and the A/C tensioner pulley needs to be replaced. Discontinued part from Mitsu and had a $120.00 list price. Was not able to find any A/M ones either. Cleaned up the bearing and pulled the numbers off the seal on the bearing.Fantastic to replace just the bearing with the same bearing that it came with! I have always had great luck with NSK bearings as well.

Ordered a pair of NSK 6203-2RS ( NSK part number for the same thing 6203DDU). I received 2 6203ZZ bearings with with metal side shields instead of rubber side shields. The NSK website says these are only suitable for electric motors, not for car engine bays where it can be dusty of get wet. On the plus side Amazon managed to send me NSK bearings of the correct size. 2 they are made in Poland where they are known for high quality machine tools.

Quality product.
