OPTIBELT Timing Belt Pulley Steel 50 mm 8 mm Pitch 72 Tooth TB 72 8M 50

OPTIBELT TB 72 8M 50 timing belt pulley is a precision-engineered mechanical power transmission component manufactured from robust steel. It is designed for use in industrial and manufacturing settings requiring reliable belt-driven motion control. The pulley has 72 teeth with an 8 mm pitch, making it compatible with HTD (High Torque Drive) belts of metric 8M profile.

This pulley accepts belts with a width of 50 mm, ensuring efficient power transfer in heavy-duty applications. The tapered bore design allows for easy mounting and secure fit on shafts with 9WF taper bushings, specifically the 2517 type, which enhances assembly precision and reduces vibrations during operation.

The flanged construction provides additional support for the belt, reducing slippage and wear, thereby increasing the pulley’s service life. Its outer dimensions include an outside diameter of 181.97 mm and a flange diameter of 192 mm, accommodating precise mechanical fittings. The pitch circle diameter is 182.35 mm, aligning perfectly with compatible timing belts.

Certified to meet RoHS requirements, this pulley represents a commitment to environmentally friendly production while maintaining high-performance standards. It is suitable for industrial machinery, manufacturing equipment, mechanical drives, and other power transmission systems that demand durability and accuracy.

Applications include mechanical, fluid power, and tool industries where timing belt pulleys are essential for synchronizing movement and driving loads with high torque. This product supports maintenance and upgrade needs for industrial belt transmission mechanisms.

The pulley features a 50 mm belt width suitable for 8M profile timing belts. Constructed from high-quality steel ensuring durability and strength. Designed with a tapered bore type and flanged design for secure assembly and operation.

Measures an outside diameter of 181.97 mm and flange diameter of 192 mm. Complies with RoHS standards indicating environmentally responsible manufacturing. Compatible with 9WF taper bushing type 2517 for secure mounting.
