No packing bearings or installing seals—this CE Smith hub comes ready to go. It’s pre-greased with heavy-duty marine grease and already has the inner and outer bearings (L44649), races (L44610), grease seal, grease cap, lug nuts, and cotter pin in place. Just slide it onto your BTR spindle and torque the 1/2" studs. Each hub supports 1,350 lbs for use on 2,700-lb axles, so you can get back on the road or water fast.
This hub’s galvanized finish holds up against corrosion from saltwater and wet conditions. Even the small parts—lug nuts, cotter pin, and grease cap—get zinc plating to fight rust. That marine-grade build makes it ideal for trailers that see launch ramps or long seasons outdoors.
The included case keeps everything together until you need it. It’s compact enough to store in your tow vehicle or toolbox so you can carry a spare hub ready for an emergency swap. When a bearing fails on the roadside, you’ve got a full replacement kit in one spot.
Designed for BTR spindles with 1.063" bearing surfaces, this hub uses the standard 5 on 4-1/2" bolt pattern for wheels up to 14". The grease seal (#34823) has a 1.249" inner diameter and 1.983" outer diameter for a snug fit that helps keep water out. It’s a simple, proven setup many trailers already use.
The sturdy iron hub body is built to take steady loads trip after trip. Combined with marine-grade grease and corrosion protection, this CE Smith assembly is made to keep your wheels turning smoothly whether you’re hauling equipment or launching at the dock.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Hi Eric, this hub is designed for a BTR spindle which is slightly longer than the common BT8 spindle. You more than likely have a BT8 spindle that takes 1" L44643 diameter bearings for both the inner and outer. You need CE smith idler hub part # CE13215 for a BT8 spindle. You will want to double check the inner diameter of your current bearings to make sure this will work however I am about 95% sure this is what you need because it's a common mistake. Let me see if I can help you with returning the this one.
