Worm Reducer-Replacement of SITI Series I-MI90 Single Gearbox and Geared Motor

Product Introduction

The I series compact metric worm gearbox is ideal for applications where other gearboxes cannot be used. Compared to similar American square cast iron designs, it is smaller in size and lighter in weight, saving space and cost. Its transmission ratio can reach up to 8,000:1, with a torque range of 140-26,500 pound-inches. It is an ideal choice for commercial and industrial applications that require high dimensional requirements. Our worm gearbox is specifically designed to replace the SITI Worm Geared Motor, with excellent performance and reliability. Our company offers replacement worm gear reducers for this brand at a reasonable price, emphasizing that our products are replacement parts, not original parts. If you need to purchase original parts, please contact the original supplier for purchase.

Worm Reducer

Product Structure

The worm reducer is composed of several key components:

  • Worm shaft
  • Worm gear
  • Housing
  • Bearing
  • Seal
  • Lubrication system

The worm shaft transmits power from the motor to the worm gear, which in turn transfers power to the output shaft. The housing provides protection for the internal components, while the bearing supports the shafts. The seal helps prevent lubricant leakage. The lubrication system ensures that the gearbox is properly lubricated for optimal performance.
