Timing belt (synchronous belt) and pulley (synchronous wheel) are very important for linear motion system or motor driving system

It can transmit the power force from engine/motor to the linear motion system or other motion unit perfectly

It also can be used for speed reducer to make sure the transmission more stable

Different materials of timing belt pulley: Aluminum, steel, brass based

But the aluminum pulley is most popular in laser cutting machine applicationt

Different types timing belt pulley with different shapes

In laser industry, the AF types 3mm tooth pitch used very popular

The key spec for a timing belt pulley such as pulley shapes: AF type, BF type, BS type & CF type

Also the total amount of booths, pitch of tooth, the timing belt width matched, the hole size of pulley are very important

In laser cutting machine industry, the 3mm tooth pitch, 20 or 24 amount pulley tooths, 15mm pulley belt width are very popular one

The different packing way for pulley and timing belt

The closed rubber timing belt HTD228-3M and timing belt pulley AF 3mm tooth pitch with 20 amount tooths

Different types rubber timing belt (synchronous belt): STPD type and HTD type

And the HTD types is very popular in laser cutting machine, for example HTD3M-15mm

It means the 3mm timing belt tooth pitch and 15mm width timing belt

The different material based timing-belt: Rubber timing belt and PU timing belt

The rubber timing belt with higher quality and life

The closed loop timing belt and open timing belt also used in laser cutting machine together

loop timing belt for xy aixs speed reducer of motor, and open timing belt for xy linear guide rail system

The popular open timing belt such as: HTD3M-15mm, HTD3M-20mm and others
