Tigear 2 Worm Gear Reducer

TIGEAR-2 is the only complete line of single-reduction, right-angle worm speed reducers specifically engineered with advanced sealing and bushing system technology that can actually lower your total cost of ownership.

TIGEAR-2 is offered in 10 sizes covering center distances from 1.33” (Size 13) to 4.75” (Size 47). It has a 30% increase on average output torque (up to 6,800 in-lbs.), and because of the consistent torque capacity increments between case sizes, equipment designers can optimize reducer size selections for cost, performance, and life.

The DODGE TIGEAR-2 reducer design has a totally enclosed, ventless sealing system that contains a factory-filled synthetic lubricant that actually runs cooler, as well as eliminates the need for routine oil changes. Its precision-manufactured gear geometry balances multiple gear parameters for dramatic improvements in torque capacity, efficiency, and operating temperatures. TIGEAR-2 is the only worm reducer with the GRIP TIGHT® tapered bushing system.

All combined, TIGEAR-2 raises the bar, offering you innovation and manufacturing expertise that is unmatched in the industry.

How to order example:
30=Case Size (in this example 3" shaft center distance)

L=Left Output
56=Motor frame size

Case size Options

  • 13 (1.33" shaft centers)
  • 15 (1.5" shaft centers)
  • 17 (1.75" shaft centers)
  • 20 (2" shaft centers)
  • 23 (2.25" shaft centers)
  • 26 (2.625" shaft centers)
  • 30 (3" shaft centers)
  • 35 (3.5" shaft centers)
  • 40 (4" shaft centers)

Input Options

  • Q=Quill or C-Face
  • A= Adaptable (3pc coupled with C-Face bell-housing)
  • S=Separate (solid input shaft for belted or coupled motor connection)

Ratios from 5:1 to 60:1

Output Options

  • L=Left output shaft (when looking at motor input shaft)
  • R=Right output shaft
  • LR=dual output shaft
  • H=Hollow output shaft (HA=alternate diameter hollow output)

Motor Frame Sizes

  • 56= Nema 56C motor frames
  • 14= Nema 140TC series motor frames
  • 18= Nema 180TC series motor frames
  • 21=Nema 210TC series motor frames
  • 25=Nema 250TC series motor frames

EZ Kleen models are designated with a Z between the Input option and ratio, for example 30QZ60L56.  E-Z Kleen reducers are washdown capable with a 13-step coating with stainless color top coat.  They also feature 300 series stainless shafts and hardware.  Harsh duty seals are also included.

Ultra-Kleen Tigear 2 reducers are the ultimate in paint-free washdown reducers.  Housings are 316 stainless steel, shafts are 300 series stainless and they have harsh duty seals.  Ultra-Kleen models are designated with a SSat the beginining of the part#, i.e. SS30Q60L56.
