The Concentric Maxi Torque keyless hub-to-shaft connection system. http://cmtco.com/concentric-maxi-torque ,, 
http://cmt.shotgunflat6.com/images/uploads/cmtspreadblue2crop.png Engineers at Custom Machine and Tool Co., Inc. found that fasteners used to connect components to high speed shafts had to have lower intertia and create fewer vibrations. We also knew that component alignment, accuracy, holding ability and runout became critical at higher speeds. When no other company could offer a compact bushing for shafts less than an inch in diameter, CMT was up to the task. We decided to design, build and patent one.

=== Hour glass ===
http://www.kinematicsmfg.com/quality/hourglass-technology/ (Scan design with laser scanner and reproduce 3d printer)
Kinematics’ patented hourglass design is unique because it can withstand a survivability load that is four to nine times greater than loads carried by typical slewing drives. The special hourglass shape of the drive allows more teeth to be engaged at one time, enabling much higher torque endurance. Our technology delivers a stronger and more durable drive so your equipment can perform longer and more reliably.
=== plastic ball bearing ===
http://www.youtube.com/watch?v=0sfNEHDPucs xiros
Free from maintenance and lubricants, suitable for extreme environments
Xiros plastic ball bearings from igus are designed for applications where the use of grease or lubricants is prohibited. The food and drinks industry, in particular, bans the use of such substances altogether. The design of igus xiros ball bearings is the same as conventional steel bearings, consisting of an inner and outer race, a cage and a number of balls; the only difference being that the races and cage are made from igus tribological polymer materials. These plastic materials are self-lubricating and thus negate the need for lubricants.

=== Worm gear ===
http://www.thingiverse.com/thing:8821
Description
Ok, once you have an involute gear library AND a trapezoid thread library, you can easily make the simplest of worm drives, i.e. the non-throated kind.
Like all worm drives, the gear advances by one tooth for each revolution of the screw but with non-throated ones, there is only a single point of contact at any one time, and so torque and wear capabilities are limited.
UPDATE:
As I pointed out in the comments, AFAIK a trapezoidal profile for the worm screw is all you need to match the worm gear's involute.
To make them mesh, all I did was to make sure that: 
1. the pitch is the same (distance from crest to crest), 
2. the pressure angle of the gear is equal to the angle of the sides of the screw profile, 
3. the distance between screw and gear is equal to the gear's radial pitch plus the screw's mid-profile radius, and 
4. the twist on the gear is equal to the gear's pitch radius divided by the screw's mid profile radius, with a sign depending on the screw's handedness.
Many methods have been used for control of backlash in geartrains. George W. Michalec's book Precision Gearing: Theory and Practice, published in 1966, has a good description of many different methods. Most have disadvantages such as increased size, weight, and cost. Examples are split, spring-loaded scissor gears and the use of auxiliary geartrains. from https://www.google.ch/patents/US6285339

ZZ means it has a metal shield on both sides, 2RS means it has rubber seals on both sides. The rubber seals will keep more crud out of the bearings. There may be some bearings or manufacturers to stay away from, but I am not aware of any. The tolerance differences between the various ABEC ratings are so small(>.0005") that it doesn't matter what the ABEC rating is.

https://www.skf.com/africa/en/products/plain-bearings/spherical-plain-bearings-rod-ends/rod-ends Rod ends consist of an eye-shaped head with integral shank that forms a housing for a spherical plain bearing. As a rule, rod ends are available with left- or right-hand female (internal) or male (external) threads. SKF supplies rod ends with a threaded shank with a right-hand thread as standard. With the exception of rod ends with the designation suffix VZ019, all rod ends are also available with a left-hand thread. They are identified by the designation prefix L.

https://www.youtube.com/watch?v=foyZLBneV08 Rod end bearings are a very popular component used in homebuilt experimental aircraft. This short video demonstrates some of the important details about properly installing these components to keep them safe and reliable in your aircraft. 
https://www.youtube.com/watch?v=YUqpI1FoGIA rjoint and spherical 
https://www.youtube.com/watch?v=JeAYfEh_I_0 Rod end ball joints (also called Heim joints) are used in applications where three degrees of rotational freedom are needed. They are typically heavy duty items (metal construction) and rated to withstand thousands of pounds of load. The interface between the ball and its socket is usually snug: this is beneficial because it eliminates any play at the interface; however, if the application calls for very low friction in the joint it will generally loosen up over time.
