Trailer wheel bearings

Trailer wheel Bearings

Trailer wheel bearings come in many variations and sizes of either sealed or taper roller bearings. The variations of trailer wheel bearings are vast due todifferent weights and manufacturers of axles. Towing and trailers can offer a choice of economy andpremium bearings. Our premium bearings come frommanufacturers such asTimken, NTN, Koyo and more. Yourbearings maybe identified by a unique number which can befound marked on the bearing. If the number has worn off your bearings over time, You canidentify your bearing with accurate Internal diameter, externaldiameter and widthmeasurements.

Sealed Bearings

Sealed bearings come ready to fit and do not require greasing. Usually a large 1 piece bearing that is tightly fitted in to the hub, often secured by a circlip. To fit and remove a sealed bearing we recommend the use of a press because they are such a tight fit. European Axles were the first to introduce sealed bearingsbut they are are becoming more popular in the UK.Sealed bearings are also known as Sealed for life (SFL) this basically means that the unit is sealed and can not be maintained. The most common use for a sealed bearing is on the following drums and trailers;

  • Al-ko drums
  • Knott SFL (P, X, Y series) hubs and drums
  • Ifor Williams manufactured after 1992
  • Some peak, Indespension and Meridith and eyre
  • Erde and daxara (some)
Most Sealed bearings need to be torqued correctly to offer maximum bearing life.

Taper Roller Bearings

Trailers still commonly use taper roller bearings. It is easyto maintain and inspect taper roller bearings. Although it is possible to change taper roller bearings without a press it is easier with a press. When tightening taper roller bearings werecommended to torque to 70Nm, rotate the wheel at least 1 full revolution then loosen off and tighten finger tight, as over tightening will destroy the bearings. Ourextensive range of taper roller bearings willsuit a variety of hubs and brake drums.

These include;

  • Knott Hubs and drums (A, C,E, N, R & V series),
  • Al-ko Drums,
  • Bradley Drums (All),
  • Indespension (most)
  • Meredith & Eyre
  • Peak trailers (most)
  • Erde and daxara (some)
  • Ifor Williams Pre 1992
  • and many more
