Del Mar Roller Corp. Two Wheeled Roller-No Markings

Hi,

The roller pictured is one of two rollers supporting a wooden framed sliding patio glass door. I believe the rollers are at least 10-15 years old and have worn down to the point where the door will no longer slide. Upon inspection, one of the rollers has worn down off its track of the ball bearings while the other has held up decently. I plan to replace both of them. I have also enclosed the top of the door with two little white wheels. I am assuming those are to guide the door on top. One is missing, but I don't believe this is the main problem. However, if you have a suggestion or replacement for two sets, please let me know.

We plan on renovating our house in the next 12 months so I don't need something that will last forever, but I do need something that will last so we can enjoy actually getting on to our back deck. I'm not sure if this will make a difference in what you recommend.

Thanks for the help!!!

Thanks! Is there any grease needed for the top rollers? Or should I clean out the interior track before replacing them? As you can see from the picture, the top rollers are pretty greased up/dirty so I wasn't sure the correct way to go. Also, do you recommend the track lubricant, and if so, how often?

Hi, I am looking to replace my assembly also, and this picture is the same as I have. I see you have 4 different models that all measure the same but vary significantly in price. Can you tell me the differences between them and which one would offer the best value for the money spent? Model #s are: 81-018 ; 81-149 ; 81-141 ; 81-137. The door is a wooden inner door between porches and not exposed to weather. Thank you.

Thanks for the explanation Tom. Can you explain the differences between 018 and 141 then? THey appear to have the same measurements. I am not sure which to order except that 141 appears a bit sturdier than 018. Also the top gap between the metal seems to be slightly wider on the 141 (which is more similar to mine). Thank you.

"d-uh"!!! LOL, I just didn't see that! Thanks for pointing that out. Tabs on the bottom for me! I appreciate the help and will be ordering these.

Thanks for the pictures. Having same issue as Arlington but home was built in '85 with a Morgan door. The 81-018 looks like the answer and have ordered them.
