Review of Redline Seals for Trailer Bearings SL150


Today were going to review part number SL150. This is the red line grease seal. This is a single lip design grease seal which is designed for use on an agricultural hub. This does have an overall diameter of 2.332 and an internal diameter right here of 1.500. This grease seal, if you go to the product page for this part number, itll also list a seal cross-reference chart and it will list the different brands of seals that are out there and then itll list the part number for that brand that would match this part number SL150. So you can use that if you have a different part number and you can cross-reference it.

And that should do it for a review on part number SL150.

I liked the video ..but..what I'd like to know is ...my spindle mjked out at 1.500 O.D and my hub miked out at 2.125 I.D so do I order the part that is same size as the i.d and o.d or do I order a seal that is a slight bit bigger o.d. so it holds the hub seal from moving? Thanks Niles

@NilesF You order to match your ID's and OD's. As expected, they fit snugly and must be carefully driven into place. I have attached a video demonstrating the replacement of bearing and seals. The closest seal we have is the Redline # SL150 which has a 1.500 ID, BUT a 2.332 OD. I would re-check your OD measurement on the hub rather than the bearing that may have been distorted when it was pulled out. Also report back any part number that is etched on the seal.
