There are 3 types of Sugihara Guidebar – Pro Laminated, Pro Solid and Light Type pro. Have a look at the second picture above in the gallery to see how these bars differ.

What makes a Sugihara bar so good? This is a difficult question to summarise easily.

Sugihara bars started manufacturing chainsaw bars in 1967 by Hideo Sugihara. Japan has always had a reputation for excellence forging and working steel. Having the knowledge to manufacture quality chainsaw bars is not something that is gained overnight. It is a complex process of which cutting out the initial bar is only one part.


Steel has different properties dependant on how it is heated then cooled. Sugihara bars may go through the process of heating and cooling up to 4 times on different parts of the bar in order to gain maximum performance. The rails need to be accurately cut and hardened but over hardening can make them brittle. The bar body needs to be stiff yet flexible. We have used a number of different chainsaw bars over the years including all the major manufactures. Sugihara bars are the hardest wearing bars out there. Even their laminated bars will outlast rivals.

On the single piece pro and light type bars the hardness of the rails is measured at HRC 60. Compare this to Stihl at HRC 57 and Oregon at HRC 55 and it is clear why these bars last longer. They are so hard they resist most flat files when it comes to bar dressing (we recommend a diamond dressing knife which can be found here).


However bear in mind they are more ‘thoroughbred’ in that if they are mistreated and the bar gets over heated they are more prone to chipping. In the wrong hands these bars have a far shorter lifespan so please be aware of your bar maintenance:

  1. Check your drive rim/drive sprocket BEFORE you buy a new bar – if worn you MUST change this before running a brand new high tolerance bar

  2. Old chains [yes if they have a been used ‘a few’ times this counts as old – must NOT be run on a new bar [or you can but you will likely wear the bar much faster]. If in doubt do not do it.

  3. DO bed in your new bar and allow all the different parts to begin the bedding in process

Excellent Service

I needed a longer bar and chain for my chainsaw as I had to deal with a fallen tree that was bigger diameter than my existing 18” bar could cut even cutting from both sides.
I didn’t want to over extend my saw and the selection tool on the website made it so easy to specify the 20” bar and associated chains (1 crosscut and one ripping chain)
The prices were good and much better value and availability than the saw manufacturers options.
Delivery was prompt and the best bit is that the conversion to a 20” saw has transformed it!
By keeping within the maximum bar parameters the engine is still able to rev fully under load without bogging down and the cutting rate is improved more than the 11% bar length increase.
I have already recommended this upgrade to someone I work with and they have ordered the same upgrade but from a 16” to 18”.
I will order again- Thanks
