Avoid Bearing Failures

25 Sep 2013

The number ONE reason for boat trailer nightmares is Bearing Failure?

 Get your bearings serviced regularly – at least once per 6 months, and definitely before a major trip. Even if your trailer is not being used, condensation of air occurs in the bearing cavity and can cause rust to commence. Deterioration can happen quickly; and often results in problems occurring at the worst possible time.

 Check the grease levels yourself, either by removing the cap or looking through the clear lens of the Durahubs (that Duralite use). Milky grease is a sign that it has been compromised by water.  Repack the bearing with grease if required, but never overfill the cavity. 

 Ensure your bearings have a cap, cover or bearing buddy. Covers can and do fall off; however they should be replaced immediately. So not submerge the bearings of the trailer in the water, without a bearing cover of sorts. You’re only inviting water in, and major problems down the line. All Duralite trailers are supplied with high quality bearing buddies or covers.

Wait for the bearings to cool off before submerging the trailer in water. After a long trip to the ramp, your bearings & grease will have heated up – but once the bearings are submerged, the cool temperature will cause the grease to contract and ‘suck in’ water into the bearing cavity.

Feel your hubs for excess heat when travelling.  They should not feel any hotter than a cup of coffee. If they are ‘overheating’ then if prepared, attend to them yourself, or head to the nearest garage/ workshop for some assistance.

Use the correct grease with your bearings; this should be high temperature marine grease, ideally lithium based, which will not degrade with water.

Carry a spare set of bearings with you; and better still a spare hub with bearings in it – to make any changeover very easy. Also ensure that you have the correct bearings, and that these are well seated in the hub. 

Use double lip marine grease seals for better protection against water ingress. Duralite uses the highest quality seals in the industry.

Ensure your trailer is built with the best quality componentsDuralite trailers are built in a quality controlled environment, with quality components and trailers are backed up by a proven warranty.

Duralite uses the highest quality bearings, and a high lithium, high temperature marine grease.  Duralite has quality control systems in its factory and specialised equipment for injecting grease into the bearing & cavity of the hub. Hubs are cleaned prior to assembly to ensure no dust or metal filings are present.
