What are the specifications of chainsaw chains?

Chainsaw chains are available in 3 sizes.
Saw chain parameters mainly include pitch, thickness of intermediate guide teeth, and shape of cutter teeth.

1. Pitch: The pitch of the saw chain is the distance of 3 rivets divided by 2; it corresponds to the pitch of the sprocket. Including 1/4, 0.325, small 3/8, large 3/8, 0.404 (in inches; 1 inch = 25.4mm).
2. Thickness of the middle guide tooth: corresponding to the width of the guide groove of the guide plate. Includes 0.043, 0.050, 0.058, 0.063 (in inches; 1 inch = 25.4mm).
3. Tooth shape: Determines the smoothness of the cut wood. Including rounded corners, right angles, and arcs.
Chain saw, also known as chain saw, is a portable saw powered by a gasoline engine. It is mainly used for logging and wood building. Its working principle is to perform shearing action by the lateral movement of the staggered L-shaped blades on the saw chain. Chain saws are generally divided into motorized chainsaws, non-motorized chainsaws, etc.
According to the same source, chain saws are divided into: gasoline saws, electric saws, pneumatic saws, and hydraulic saws. The advantages and disadvantages of these four types of power chain saws are obvious:
Gasoline saw: strong mobility, suitable for field mobile work. However, it is noisy, troublesome to maintain, and generates more heat.
Electric chainsaw: stable power, quick start, bulkier than other saws. But if the line is too long, it will be inconvenient to move.
Pneumatic chainsaw: safe and pollution-free, with low noise and light weight. However, an air compressor must be attached, which increases the floor space and is subject to conditions.
Hydraulic chainsaw: The power is sufficient, but the start-up is slow and the work is stable. The volume of the hydraulic pump station is smaller than that of the air compressor. higher cost.
