What carbides should I use?
Carbide Length also is a very important consideration. If you are a trail rider running 96 or fewer studs, we recommend you go with a 4.5-6” carbide. If you run more than 96 studs, we suggest going with an 8-9” carbide. If you are a mountain/powder rider, a shorter 4-6” carbide will suffice.
Are longer carbides better?
A 121” track with more than 96 studs may also require a longer carbide length. A 6” carbide length is good for the intermediate riders who occasionally push their sleds to the limits. When the sled is maxed out with studs, and/or has a 144” or longer track with paddles, an 8” or longer carbide is acceptable.
What do carbide runners do?
Sharp angle carbide sections in the runner improve the steering control on an icy surface when they are new & sharp but are also the primary wear surface which dulls the sharp edge very quickly.
Are Wearbars and carbides the same thing?
Wear bars are made out of regular steel. They are usually OEM ski runners. Carbide runners are made out of carbide steel and are preferred by enthusiasts and hard-core snowmobilers. Wear bars are perfect for beginners and casual riders, where carbide runners are more durable and last longer.
Can you sharpen carbides?
Carbide teeth are so hard, they can only be sharpened using an exceptionally fine grit diamond wheel. Contrary to some information found online, a diamond blade used for cutting ceramic tile is way too coarse for this purpose and will ruin the carbide tip.
Does CBN sharpen carbide?
CBN wheels will even sharpen pure carbide bits and tools, although the life of the wheel will be compromised enough to probably not make it economically worthwhile. A wet CBN cutoff wheel will slice through carbide at the same speed as a diamond wheel, it just wears faster.
When should you change carbides on a snowmobile?
Registered. When the carbide inserts are flush with the host bar (or torn out) it’s time to replace. I’ve used bergstrom triple point skegs for the last 4 years and they outlast the others by a long shot.
