TRAMPA's very own Mountainboard Bearings measure 12 x 28 x 8mm & will fit in to all of the Hubs that TRAMPA has to offer. 

TRAMPA's precision made Bearings are polished to an internationally recognised ABEC 7 quality. (ABEC 3-5 is recognised as the industry standard). ABEC 7 polishing gives you a super smooth, super fast ride with extendend free rolling & top end roll speeds.

The Bearings are designed to fit TRAMPA wheels directly to 12mm axles, however using Bearing Reducer Spacers you are able to make 6001-2RS Bearings fit to Mini Spring Truck or 12FIFTIES Truck which both use 9.525mm Axles... Using Bearing reducer sleeves on 9.525mm Axles gives a very neat flush finish to the assembly insuring your Bearings spin freely.

Mountainboard Bearings are officially known as 6001 2RS Bearings. 6001 tells you the bearings size whilst 2RS means the bearing has 2 Removable Sides. During production the rubber coated sidewalls are inserted into the Outer raceway & are in contact with the inner raceway, they protect the single row of lubricated ball bearings housed within the enclosed raceways from the ingress of moisture, dust & dirt, retaining the pre-filled grease within the bearing, maintaining maximum performance to the board & rider for as long as possible. The rubber coated sidewalls come in RED, BLUE & BLACK or CERAMIC GREEN & are embossed with the TRAMPA logo proving the Top Quality!

The sidewalls are removable so you can service your bearings... Servicing your bearings on a regular basis will ensure they run well for you. Remove your wheels & take out your bearings, then using a pointy object simply pick off one side of the bearings & pop them into some solvent or fuel to dissolve any grease, i use an old tooth brush to rub the bearings gently, hopefully removing all the dirt that gets in... I pop them into another pot of clean fuel & make sure the fuel stays clean so i know the bearings are clean.. Once clean i take them out, placing onto some tissue or similar to dry out, you can rub them or blow them dry with an air line which is fun as they mae a whizzy noise! once dry i add a few tiny drops of sewing machine oil & place the bearing, open side into the wheel leaving the 1 side that still has the rubber sidewall in the outer position protecting your bearings from the further ingress of dirt getting in.... Repeat according to your riding demands, more riding = more servicing if you want best performance!

Internal Bearing support spacer used with 8mm O-Ring on 9.525mm axles - 9.525 x 13.525 x 16.5mm

This special Spacer measures 12mm (id) x 16mm (od) x 16.5mm (long) & is known as a Bearing Support Spacer. This Bearing Support Spacer fits between the Bearings, along side the 10mm O-Ring when fitting Bearings into a TRAMPA hub when mounting the wheel onto 12mm Axles.

Over time, during the usage of your board, the bearings & spacers are put under a lot of force. Ultimately this force has to go somewhere... The Bearings use a Steel ring in their assembly where as the Bearing Support Spacers are made from Aluminum. Steel is much stronger than Aluminum & when forced against each the aluminum will loose out every time! This is what happens to your spacers between the bearings, the Bearings put force onto your spacers as a consequence over time the spacers shrink... With enough time its possible for an annoying rattle to start.... That's when you fit these 16.5mm spacers with the little 10mm O-Rings to prevent the rattles!! :-)

12mm Bearing for TRAMPA All Terrain Boards 12x 28x 8mm with BLUE sidewalls & Embossed TRAMPA Logo ABEC 5 6001 2RS

Bearing conversion Spacer converts 12mm Bearings to fit 9.525mm Skate & Spring Truck TiTanium Axles

Use this handy little part to convert 12mm TRAMPA bearings to fit onto 9.525mm (3/8ths of an inch) Axles... You will commonly find 9.525mm axles on Skate Trucks or Trucks with Titanium Axles. Simply slip the Conversion Spacer into your 12mm Bearing & then insert the Wheel back onto the axle.... Couldnt be easier.... :-)

The pressed aluminium is accurately made so it fits snugly into your bearing and tightly slides over the axle. The flanged Rim allows the axle nut to tighten without squashing the bearing wall, ensuring free spinning maximum performance from your bearings at all times. The sleeve can be re used over and over again but remember to replace your bearings regularly....

8mm Rubber O-Ring to fit in Bearings - 2mm Section x 8mm Bore NITRILE 70

This O-Ring should be fitted when a 9.525 x 16.5mm Bearing Support Spacer is fitted into the wheel assembly when fitting a wheel onto 9.525mm Axles. It fits alongside the Bearing Support Spacer, in-between the Bearings. This O-Ring prevents rattles from the spacer against the bearings. Over time, during the usage of your board, the bearings & spacers are put under a lot of force. Ultimately this force has to go somewhere... The Bearings use a Steel ring in their assembly where as the Bearing Support Spacers are made from Aluminum. Steel is much stringer than Aluminum & when forced against each the aluminum will loose out every time! This is what happens to your spacers between the bearings, the Bearings put force onto your spacers as a consequence over time the spacers shrink... With enough time its possible for an annoying rattle to start.... That's when you fit these little O-Rings!! :-)
