Which Bearings and Hubs Fit Heavy Duty 3,500 Lb Timbren Axle-Less Trailer Suspension  


I bought these axels a few months back. I was wondering what size hubs/bearings fit these? My bolt pattern is 5 x 4.5

The Timbren Axle-Less Trailer Suspension # ASR35HDS05 is the heavy duty model. The heavy duty Timbren uses a spindle that is a size up from the axle capacity, so the inner bearing is the # 25580 and the outer bearing can be the # 14125A or # 15123 which is standard for 5,200-7,000 lb axles.

Unfortunately, that means that a 5 on 4-1/2 pattern won't be an option. A hub that fits will either have a 6 on 5-1/2 or 8 on 6-1/2 bolt pattern. You will either need new wheels to match the bolt pattern or a different Timbren system. If you want to stick with your current system you can use the # AKIHUB-655-6-EZ-K for an idler hub or # AKHD-655-6-EZ-K for a hub and drum.

The # ASR3500S05 uses a standard 3,500 lb spindle with # L68149 inner and # L44649 outer bearings. This would allow you to use an idler hub like # AKIHUB-545-35-EZ-K or hub and drum assembly like # AKHD-545-35-EZ-K with a 5 on 4-1/2 bolt pattern.
