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’s 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).
