Zero-Max C138801 Two-Way Crown Drive, 1:1, 3 8" Shaft, 90 Degrees, 2000 RPM Max

Description:

The Zero-Max C138801 is a compact two-way crown gear right-angle drive designed to transmit power between intersecting shafts at a 90-degree angle. It features a 1:1 gear ratio, meaning input and output speeds are equal while changing the direction of rotation. The unit uses hardened spiral bevel gears for smooth, quiet operation with minimal backlash, and is housed in an anodized cast aluminum enclosure for durability and heat dissipation.

Applications:

The Zero-Max C138801 crown drive is used in packaging machinery, conveyors, automation systems, and material handling equipment. The Zero-Max drive is commonly installed where space is limited and power must be transferred between perpendicular shafts with high efficiency and reliability.
