Description of Boston Gear NJ21B Pressure Angle

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 6 for applications where transferring torque is more important than 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.

Great Pressure Angle Gears

The gears I purchased from Boston Gear are exceptional. According to my experience, they are durable and reliable with minimal noise .The pressure angle is perfect for my machinery and runs smoothly. The only con I experienced was a higher price point, but the quality of the product justifies the cost..

Pros
  • Durable and reliable with minimal noise
Cons
  • Higher price point

Heavier gears than I expected.

Bought these for a side roller I was making. Worked great but ended up with a huge bead roller and I'm not sure when I'll need it. But it's fun to build.

Pros
  • Gears
Cons
  • Slightly torn
