Ball bearing pulley with 8 mm deep U-groove, 250 kg, metal pulley for lifting guide, inner diameter (40 x 13 mm)

There are two carbon steel ball bearings inside the pulley to reduce wheel friction. The pulley rotates more smoothly and quietly. Made of bearing steel, it is rustproof and corrosion-resistant. It also prevents the pulley from corroding when used outdoors. Compared to other pulleys, the pulley wheel support plate is thicker, the wheel is stronger, and the load-bearing capacity is higher. Applications: Steel cable pulleys, transmission equipment, industrial pulleys. Offers durable resistance to heat, impact, and corrosion.
