Keep a surgical reactivity driving with the official rocket bearing OTK (Original OTK Kart Parts), calibrated with the dimensions of 10 x 26 mm. This high precision bearing is the original spare part essential to ensure the perfect and friction-free pivoting of your front rockets on the frame of the group chassis OTK.
Subject to enormous radial and axial stresses during intensive turning phases and repeated passages on the vibrators, this bearing benefits from a higher factory manufacturing quality. Its treated steel balls and its optimized sealing flanges limit the intrusion of brake dust and track gum debris. A rocket bearing in perfect condition eliminates the hard points and the parasitic game in the column, guaranteeing a direct feedback from the front train in your hands.
Technical characteristics:
-
Inner diameter (axis): 10 mm
-
Outside diameter: 26 mm
-
Application: Front rocket pivot (rocket / chassis connection)
-
Chassis compatibility: All chassis of the group OTK (Tony Kart, Kosmic Racing Kart, wished, Redspeed, LN Kart, Gillard) equipped with rockets with axes of 10 mm.
👨🔧 -. The Tip in Michel (the corner of the expert)
* "Hi the artists of the rope point! We go hours to refine the pressure of the tires or the carburation, but we too often forget these small bearings hidden in the heart of the front rocket. Yet a tired or seized rocket bearing, it is a direction Heavy, a kart that" refuses "to turn or engages a sharp blow. In short, it's impossible to be regular at the time !
My old sea trick to check your pivots: the test of the free rocket !
Regularly put your kart on the carriage, disconnect your two direction rods directly at the rockets, and rotate each rocket with the left right. You must feel an ultra-fluid movement, as if it floed in the air. If you feel the slightest "cran", a hard point or a sound of sand that cracks, do not look: the bearing is dead, stuffed with platelet dust or gum.
When installing the new 10x26 mm bearing in the rocket, use a good diameter socket to support only on the outer ring rolling during insertion. If you tap on the inner ring to push it off, you will mark the new balls before you have asked the kart on the ground. A little light lubricant spray (Avoid thick fat that holds dirt) and your train before will find a precision of Formula 1! "*
📐 -. The replacement guide: step by step
1.Dimony of the front train:5 min.Place the kart on its track trolley. Remove the front wheel as well as the hub. Unscrew the steering rod connected to the rocket, and remove the central pivot screw (10 mm rocket screw) to completely release the chassis rocket.
2.Extraction old bearings:10 min.Using a bronze jet or a suitable rolling extractor, gently hitch the two old bearings housed in the body of the rocket. Meticulously clean the inside of the brake cleaner rocket housing to remove the old black fat.
3.Insertion bearings OTK new:5 min.Follow the trick in Michel: Present the first bearing of 10x26 mm straight. Press it by applying the effort on its outer ring until it stops. Return the rocket, insert the internal spacer (if present) and install the second bearing in the same way.
4.Remontage and game control:5 min.Reposition the rocket on the c of the chassis. Reinsert the 10 mm axis by adjusting your croken / hunting / hunting eccentric. Tighten the nut to the couple, reconnect your rod and check that the rocket rotates freely and without any vertical game.
❓ -. FAQ SEO (Frequently Asked Questions)
Q: How many bearings need to be karted ?
A: Each front rocket usually requires 2 bearings (upper bearing and lower bearing) to guide the 10 mm pivot axis in a perfectly stable manner. If you want to rebuild the entire front train (right side and left side), you will need to order a total of 4 bearings.
Q: Does this 10 x 26 mm bearing suitable for minimal / cadet kart rockets ?
A: The group OTK historically uses 10 mm pivot axes on the majority of its adult chassis (OK, KZ, Rotax), ride 10x26 mm a must-have standard. However, on some small category chassis (microphone, mini, rookie) or older generations, the dimensions may vary (8 mm axes for example). We advise you to measure the diameter of your rocket screw axis before placing an order.
Q: Should we grease this rocket bearing before assembly ?
A: This original turnover OTK comes pre-lubricated and equipped with flanges of sealing protection. It does not require adding inner grease before installation. For maintenance during the season, a simple exterior cleaning followed by a fluid lubricant spray (WD-40 type or lubricant to the PTFE) is enough to maintain its freedom of rotation without attracting the abrasive debris from the track.
