Front hub CRG all. 17 m Double Bearing

2. Complete description of the product (H1: front hub CRG Aluminum Ø17 mm - Size M - Double Routing Version)

The front hub CRG 17 mm in size m (Medium) is a high-end frame of the original manufacturer chassis (Original CRG Share), specially developed to refine the guidance of 17 mm rockets (currents on the chassis of the categories Mini, minimal, cadet, mini 60).

The great particularity of this version lies in its internal architecture to double bearing. Unlike standard hubs that only use one bearing at each end, this model integrates two juxtaposed bearings on each side. This technique makes it possible to double the contact surface on the rocket, offering a distribution of colossal loads and increased rigidity of the front train. By limiting the flexion of the rocket axis during large supports or passages on the vibrators, this hub guarantees a perfect and constant geometry of your front tires.

Technical characteristics:

• Inner diameter (bore): 17 mm (rockets of 17)

• Size: M (medium) - offers the perfect compromise between mechanical agility and stability

• Material: High Density Aeronautical Aluminum, CNC Machine

• Technology: Double bearing by face for ultra-rigid guidance and minimized wear

• Compatibility: Chassis of the group's brands CRG (CRG, Maranello, Dr Kart, etc.) and 3x58 mm intermedial standards

- 3. Tip in Michel (the corner of the expert)

* "Hi mechanos and future champions! This double-bearing hub in size M is a sacred technical trick. When the grip rises on the track or the young people start to climb the vibrators a little strong, the rockets of 17 can suffer and flex Subtly. With four bearings in the front, the train is locked, it's hyper precise driving !

My obligatory trick for this model: be hyper pickle on the cleanliness of the rocket. As there are twice as many rolling surface that slides on the axis, the slightest dust or small metal burr will block the hub halfway. Pass a very fine emery shot if your rocket is marked, then clean the brake cleaner.

Put a veil of WD40 or very fluid fat on the axle before threading the hub. When tightening the rocket nut, go step by step: if you taste the bearings too against each other, the wheel will not turn more freely. We want it to turn like a clock so you do not lose advance speed! "*

❓ 5. FAQ SEO (Frequently Asked Questions)

Q: What is the advantage of the double bearing relative to a single rolling hub ?

A: The double bearing increases the support surface on the axis of the rocket. This makes it possible to better distribute the lateral loads in turn and drastically reduce the flexion of the 17 mm rocket. On the track, this results in a more stable front, a more precise guidance in the sinuous and a more uniform wear of the bearings.

Q: Is this hub compatible with 25 mm rockets (adult categories ok / Rotax) ?

A: Not. This hub has an internal 17 mm bore, which matches the standard of rockets for mini, minimal or cadet category karts. Adult karts use 25 mm or 40 mm (for KZ) rockets.

Q: Is it coming complete with its integrated bearings ?

A: Yes, this model is delivered "complete", which means that the four high precision bearings as well as the internal spacers essential to their good alignment are already assembled at the factory inside the aluminum hub body.
