The ice hockey puck works despite having a high coefficient of friction because of the ice surface. You have one high friction surface (puck) that is offset by a virtually frictionless surface (ice). In the case of the roller hockey puck, the relationships are inverted. The playing surface generates much more friction than ice, so we needed to reduce the frictional resistance of the surface of the hockey puck.
We've done this in two ways:
1- Reduce the coefficient of friction of the puck materials.
This was easy enough to do. Utilizing a thermoplastic polymer glide peg to raise the rubber off the playing surface enabled the puck to slide freely on most non-ice surfaces. Most roller hockey pucks perform effectively in this regard, however there is one caveat to their success:
They only function when the puck is perfectly horizontal.
2- Reduce the puck's 'coverage'.
Below we take a look at the coverage area of our three hockey puck examples:
Hockey puck coverage
The Ice Hockey Puck basically has 100% coverage, the entire flat side of the puck is in contact with the playing surface. The ProPuck has much less coverage (and less friction) and the Plastic Roller Hockey Puck, even less.
How ProPuck's Coverage Is Better
Less coverage means less friction, but no coverage isn't good either. And the hockey puck spends a lot of game time at angles greater than zero.
To reap the benefits of a low coefficient of friction, the puck to playing surface contact must be maintained when the puck is in a dynamic state.
In the above illustrations, the range of motion of the Hockey Puck is shown in relation to the horizontal plane (playing surface). The illustration above left shows the puck spinning about its center axis 'X' with a full 360 degrees of free rotation. The illustration above right show the puck's range of motion from horizontal (0 degrees) to vertical (90 degrees) and back down to horizontal for a total of 180 degrees of motion.
ProPuck in motion As noted previously, a puck in motion will both slide and rotate about its center axis at the same time. But the fact that the puck will also move at angles greater than zero creates an interesting dynamic during gameplay that lent to the creation of a glide peg that was shaped intelligently; addressing the need to maintain an uninterrupted low friction state over the entire range of motion.
The ProPuck glide peg design provides continuous and uninterrupted coverage over 360 degrees of rotation at angles from zero to almost ninety degrees.
