RWB Kit Beta - RR - RS - Xtrainer 2008-2018 RWK-B-001
Our advanced premium off-road wheel bearing kit contains all elements required for a full service of your wheel hub. Our oil seals and ball bearings have established a categorical improvement over conventional bearings. Factory-Links ball bearing features a dedicated off-road design dust seals that offers the ultimate protection against the intrusion of contaminants such as water, mud and dust.
Factory-Links bearings are packed with a heavy duty premium marine grease and an addition of a special complex thickeners which allows it to be virtually waterproof. It provides unsurpassed rust and corrosion protection.
Also to keep any moisture out, we have gone from 30% grease filling to a 60% for harsh conditions.
Our Factory-Links ball bearings are specially developed for an Off-Road use, unlike Industrial 2RS type ball bearings that offer low torque resistance and hence weak resistance to water intrusion.

Swing Arm Bearing Kit: SAK-B-001
Our off-road premium swing arm kit is designed from ground up to be the most comprehensive OEM replacement kit available on the market. It contains all OEM quality elements required for a complete overhaul of your swing arm bearings.
Our premium kits contain all elements required for a full OEM quality service of your swing arm. Our dedicated off-road design of needle bearings, collars, pins and dust seals are specifically manufactured in order to reach the stringent OEM quality requirements, in terms of materials, dimension tolerances, hardness and surface roughness.
Our kits will bring your bike swing arm back to its former condition as defined by manufacturers.
HEAVY DUTY THRUST NEEDLE BEARINGS
Heavy duty thrust needle bearings handle much larger radial and thrust loads. Unlike cheaper solution as POM, they also provide a much lower coefficient of friction between the swing arm and frame.
PINS
Pins are precision turned, induction hardened and polished in accordance with tolerances set by vehicles' manufacturer. The material employed is SAE52100 high grade bearing steel, it is hardened to above HRC60 and then the raceway is precision grounded.
COLLARS
Collars are precision turned, polished, hardened to HRC48 and then Zinc plated. The material used is automotive standard SPCC steel.
DUST SEALS
Dust seals are made of Nitrile Butadiene Rubber and strictly molded to exact OEM specifications. They prevent abrasives, corrosive moisture and other harmful contaminants from entering bearings.
HEAVY DUTY NEEDLE BEARINGS
Heavy duty needle bearings are full complement drawn cup, induction hardened SPCC steel with internal clearances particularly suitable to off road racing use (high shocks and loads).
