Take the wheels off the bicycle beef before greasing the wheel bearings.A mixture of 50 percent white teflon bicycle grease and 50 percent green axle grease works well on Trailer wheel bearings.Don't make the bearing cone too tight when screwing it back into place. Bicycle wheel bearings shouldn't have any play in them and need to roll smoothly.

Trailer wheel bearings should last for years and provide you with thousands of miles of travel---but they won't last forever. In some cases they even fail completely if they haven't been maintained correctly. Part of a maintenance schedule should include replacement of car wheel bearings before they fail. The procedure isn't that difficult if you have about an hour and a few small tools. Front and back wheels are similar in procedure to change fag bearings and only require slightly different tooling.

An important aspect of bicycle maintenance is to grease the  Trailer wheel bearings. This helps to avoid costly future repairs and give you a much smoother, more comfortable ride. The car wheel bearings are between the cup in the wheel hub and a cone screwed to the wheel axle.

With constant exposure to water, mud, grime and rough road conditions, trailer wheel bearings can fail fast. SKF Trailer wheel bearings repair kits allow installers to enter the profitable trailer wheel bearing repair business.

Each SKF Trailer wheel bearings repair kit contains inner and outer bearings, grease seal and cotter pin. Six SKF kits cover 90% of  all utility and  boat trailers; three kit numbers alone cover most 3/4”,  1” and 1 1/4” axles.

Trailer wheel bearings, as most, require a slight preload so that more than one ball under the cone (inner race) will support its load. With proper preload, slight drag should be perceptible. Preload drag is small compared to drag caused by wheel loads, neither of which are significant regardless of adjustment. In contrast bearing life is affected by proper adjustment. Adjusting ball bearings to spin freely unloaded does not reduce operating friction because a bearing with proper preload has lower drag when loaded than one with clearance. For high quality bearings, preload should be just enough to cause light drag when rotating the axle between thumb and forefinger. Low grade timken bearings will feel slightly lumpy with proper preload.
