## Description

Boston Gear NB16B Spur Gear, 14.5 Pressure Angle, Steel, Inch, 16 Pitch, 0.500" Bore, 1.125" OD, 0.500" Face Width, 16 Teeth

## Features

- Make sure this fits by entering your model number.
- Transmits torque between parallel shafts to provide rotational power to another part of a motorized system
- Pressure angle of 14.5 degrees for a higher contact ratio between gears, resulting in quieter operation than larger pressure angles
- Diametral pitch of 16 for applications requiring a balance between transferring torque and controlling changes in speed and direction of rotation with precision
- Low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    No set screw? No problem
  

*by 1***4 on Reviewed in the United States 🇺🇸 on April 3, 2021*

Quality product at a decent price and extremely fast shipping. Does not have a keyway or a set screw BUT you also don't have to have either. If you know how to drill a hole then you are in luck. Just drill a hole where you want a set screw and also through the shaft you are mounting this to. Then install a spring pin through the gear and shaft. That will handle more torque then a screw and keep the gear in place. No need to weld it

### ⭐⭐⭐⭐⭐ 







  
  
    Great replacement
  

*by J***N on Reviewed in the United States 🇺🇸 on May 6, 2021*

I have a metal lathe that needed this gear size. After modifying the gear it works great

### ⭐⭐⭐⭐⭐ 







  
  
    These gears need a locking screw and need to be heat treated to reduce wear.
  

*by E***A on Reviewed in the United States 🇺🇸 on December 23, 2020*

The overall dimensions were perfect, missing locking screw.
