Boat Trailer Bearings

We supply bearings for all types of boat trailers - both tapered roller and ball bearings
The most popular bearings fitted to trailers are Tapered Roller Bearings
They come as two separate parts called the cup and cone (see diagram below).
Some are supplied with a seal built in as an integral part of the bearing cone.
Most bearings are stamped with an identification number by the manufacturer, so when you are looking for
replacements clean all old grease and dirt from the bearing and see if you can find any markings.
If there are no numbers then the bearing can be identified by its dimensions - please call for advice.
The most common bearings used on boat trailers are L44643 - L44610 and L44643L - L44610
Bearing number L44643 refers to the bearing cone without built in seal as shown on the left in both pictures.
Bearing number L44643 L refers to the bearing cone with built in seal as shown on the right in both pictures.
The same cup is used for both having the number L44610.

We also supply bearings for old style Mini hubs - these use ball bearings of the type 14/LJT 7/8”
The bearings are a single row thrust bearing - 2” outside x 7/8” bore x 9/16” wide
There are usually two bearings per hub with an oilseal which is 2.1/8” x 1.3/8” x 5/16”. See picture below.
