Hard Six Bearings

A chromium steel six ball bearing in a re-designed nylon retainer. By increasing the ball size and using a premium retainer, there is less friction, and you get quicker acceleration, more speed and increase durability.
-Larger stainless steel balls, create for less friction and the same wheel RPM
-Less Friction =facter speed, longer roll
-Higher speed, quicker acceleration
-Greater strength and durability
-Newly redesigned reinforced nylon ball retainers
-lubricated impregnated nylon retainers (holds the lube inside the retainer longer helping reduce friction
-updated improved deep grove channel helps support the strength and tolerance of the Hard luck 6 ball 608 design.

    Stainless Steel Good Times Bearings

    These are truly an all-terrain bearing with stainless steel balls and casing to provide you with a bearing that can withstand the elements.  These have a nylon ball retainer and removable rubber shields for maintenance.  The rain will not stop these bearings from rolling but as with all bearings the cleaner you keep them the longer they will roll.

    -Stainless steel races
    -Dual noncontact removable shields
    -Highest quality nylon retainers (lighter than metal and impact resistant)
    -Prelubed with Hard Luck speed Serum
    -Deep groove outer race to withstand impact

      Ceramic Great Times All-Weather Rulers

      Great Times Black Ball ceramics are the highest grade black ball ceramic speed bearings around.  The lighter ceramic balls help accelerate faster and provide less friction, and because of the strength of a ceramic, the bearings self-heal when outside debris invades the insides of the races.
      -Black ball ceramic  balls
      -Stainless Steel races
      -Dual noncontact removable shields
      -High speed nylon retainers (lighter than metal and impact resistant)
      -Pre-lubed with  Hard Luck speed serum
      -Top performance and unbelievable durability
