Lenze Locking Bush Steel 34mm Bore Diameter 25mm OD, 43mm Length, 250Nm Torque Rating ETP CLASSIC 25MM

Lenze ETP CLASSIC 25MM is a high-precision locking bush engineered for mechanical power transmission systems requiring secure and exact mounting of components.

Manufactured from robust steel, this locking bush features a 34mm bore diameter and a 25mm outer diameter, with an overall length of 43mm. It is designed to withstand torque ratings up to 250Nm, ensuring reliable performance in demanding industrial environments.

The ETP CLASSIC series offers unique hydraulic shaft-to-hub locking capabilities that enable infinite radial and axial adjustment. This feature is critical for manufacturers and maintenance professionals focused on precision alignment and quick servicing of gears, pulleys, sprockets, and similar machinery components.

High concentricity with radial concentricity of 0.04mm provides self-centering for excellent alignment accuracy. The bush enables fast, easy locking and unlocking via a minimal number of pressure screws, alongside automatic release once unlocked, thereby streamlining installation and maintenance processes.

This locking bush supports H7-h7 hub bore and shaft tolerances and operates efficiently within a temperature range from -30°C to +85°C. The product should be installed considering the external diameter requirements of the hub to safely withstand operational stresses, following guidelines for material type factors (steel × 1.7).

Steel construction ensures durability and resistance to wear under industrial conditions. Unique hydraulic locking mechanism allows precise radial and axial adjustments. Facilitates quick and reliable assembly and dismantling with minimal pressure screws.

Operates within a broad temperature range with consistent performance. Ideal for industrial power transmission, manufacturing machinery maintenance, and repair tasks. Designed for smaller diameter hubs with H7 tolerance specifications.

Manufactured in Japan, ensuring high-quality engineering standards.

Lenze locking bushes are favored in industries requiring frequent disassembly and reassembly with guaranteed repeat accuracy, such as conveyor systems, automated manufacturing lines, and precision mechanical engineering.
