Our choice of Bearings
These are angular contact ball bearings that have precision ceramic balls fitted into a precision steel race. This arrangement offers several distinct advantages over bearing-steel balls.
Ceramic balls have 60% less mass than steel balls. This is significant because as a ball bearing is operating, particularly at high rotational speeds, centrifugal forces push the balls to the outer race, and even begin to deform the shape of the ball. The deformation leads to rapid wear and bearing deterioration. A ceramic ball, with less mass, will not be affected as much at the same speed. The result is that much higher rotational speeds are possible. Acceleration and deceleration times are reduced as well.
Ceramic balls do not react with the steel raceways. One of the modes of bearing failures is surface wear created by microscopic cold welding of ball material to the raceway. The cold welds actually break as the bearing rotated, creating surface roughness that leads to heat generation and bearing failure. Ceramic balls drastically reduces this mechanism, resulting in longer bearing life.
Due to the nearly perfect roundness of the ceramic balls they generate much less heat as they rotate, which results in longer bearing life. Also, vibration levels are lower when compared to steels balls.
Less lubrication is required. Hybrid ceramic bearings are more tolerant to lack of lubrication.

We build unusual projects BlueBird K7
Read more about this unusual project we undertook as we grew up In the North of England and watching DC when 7 yrs old it was a fascinating project to undertake and provide her with JJ3000 jet power was even better...
With several customers now building there own K7's we may have started a trend for constructing this fantastic model..*
News 4th January 1967...
Donald Campbell killed at 300mph
On 4 January 1967, weather conditions were finally suitable for an attempt. Campbell commenced the first run of his last record attempt at just after 8.45 am. Bluebird moved slowly out towards the middle of the lake, where she paused for a brief second as Donald lined her up. With a deafening blast of power, Campbell now applied full throttle and Bluebird began to surge forward. Clouds of spray issued from the jet-pipe, water poured over the rear spar and after a few hundred yards, at 70 mph, Bluebird unstuck from the surface and rocketed off towards the southern end of the lake, producing her characteristic comets tail of spray. She entered the measured kilometre at 8.46. Leo Villa witnessed her passing the first marker buoy at about 285 mph (459 km/h) in perfect steady planing trim, her nose slightly down, still accelerating. 7.525 seconds later, Keith Harrison saw her leave the measured kilometre at a speed of over 310 mph (500 km/h). The average speed for the first run was 297.6 mph (478.9 km/h). Campbell lifted his foot from the throttle about 3/10 of a second before passing the southern kilometre marker. As Bluebird left the measured kilometre, Keith Harrison and Eric Shaw in a course boat at the southern end of the measured kilo both noticed that she was very light around the bows, riding on her front stabilising fins. Her planing trim was no worse than she had exhibited when equipped with the Beryl engine, but it was markedly different to that observed by Leo Villa at the northern end of the kilometre, when she was under full acceleration. Campbell had made his usual commentary throughout the run.
