Made from low carbon steel with a 0.500" bore and 1.375" mounting distance, it delivers reliable torque transmission between perpendicular shafts. Ideal for industrial applications requiring precise, durable, and efficient power transfer. ## Description This steel Boston Gear L series miter gear has a 20 degree pressure angle (PA) and a straight miter to transmit torque between perpendicular shafts to provide rotational power to another part of a motorized system. This gear has a plain bore, is made of low carbon steel (.2 percent carbon), and has unhardened teeth for 1:1 gear ratio applications where hardness and strength are not needed to transmit torque and motion. The 20 degree pressure angle provides a lower contact ratio between gears than a 14.5 degree pressure angle, resulting in higher load capacity. This gear is intended for use only with identical gears because miter gears can mesh only with gears that have the same pressure angle, number of teeth, and diametral pitch (number of teeth per inch). This Boston Gear miter gear is suitable for use in a variety of commercial and industrial applications, such as construction equipment, aeronautics, conveyors, and manufacturing equipment, among others.Miter gears have a blunt-end cone shape with teeth along the cone face and are used for transmitting torque and motion between perpendicular rotating shafts. A miter gear's pressure angle (PA), spiral angle, diametral pitch (also called DP or pitch), and its material are important factors to consider when purchasing. Gears come in several types for use in different power transmission configurations and for different applications, including spur gears (for rotating shafts parallel to each other), change gears (to increase or decrease torque and speed), helical gears (for high rates of rotational speed), internal gears (where one gear is nested inside the other), rack and pinion gears (for turning rotational motion into linear motion), and worm gears (for perpendicular shafts in tight spaces and quiet operation). Gears are suitable for use in the agriculture, automotive, construction, mining, and packaging industries, and can be found in a variety of machines, including bicycles, automobiles, and elevators, among others.Boston Gear manufactures a variety of gear drives, variable speed drives, clutches, and the components that comprise these systems including sprockets and bearings. Their manufacturing designs, production, and inspection meet International Organization for Standardization (ISO) standards for quality assurance. The company, founded in 1877, is headquartered in Charlotte, NC. ## Features - Straight miter 90 degree mesh transmits mechanical power between perpendicular shafts - Pressure angle of 20 degrees for a lower contact ratio between gears, resulting in higher load capacity than smaller pressure angles - 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 - Unhardened teeth for 1:1 gear ratio applications where hardness and strength are not needed to transmit torque and motion ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000L9P7B2 | | Best Sellers Rank | #737,088 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #13 in Mechanical Miter Gears | | Brand Name | Boston Gear | | Customer Reviews | 4.1 4.1 out of 5 stars (32) | | Item Diameter | 1.59 inches | | Manufacturer | Boston Gear | | Material Type | Alloy Steel | | Model | L112Y | | Number of Items | 1 | | Number of Teeth | 24 | | Part Number | L112Y | | Pitch Diameter | 16 inches | | UPC | 781711121566 | | Unit Count | 1 Count | ## Images ![Boston Gear L112Y Miter Gear, 1:1 Ratio, 20 Degree Pressure Angle, 0.500" Bore, 1.375" Mounting Distance, 16 Pitch, 24 Teeth, Steel - Image 1](https://m.media-amazon.com/images/I/41SblW-muGL.jpg) ![Boston Gear L112Y Miter Gear, 1:1 Ratio, 20 Degree Pressure Angle, 0.500" Bore, 1.375" Mounting Distance, 16 Pitch, 24 Teeth, Steel - Image 2](https://m.media-amazon.com/images/I/41HLAGXyhDL.jpg) ![Boston Gear L112Y Miter Gear, 1:1 Ratio, 20 Degree Pressure Angle, 0.500" Bore, 1.375" Mounting Distance, 16 Pitch, 24 Teeth, Steel - Image 3](https://m.media-amazon.com/images/I/51DQEQe7xeL.jpg) ## Available Options This product comes in different **Bore Diameter String, Face Width String, Number Of Teeth, Pitch Diameter String, Item Diameter String** options. ## Questions & Answers **Q: Is this item for 1 gear or a matched pair?** A: matched pair **Q: There were 7 in stock so i ordered 1. it said it would take 2 days to arrive. i added another gear and now it will take up to a month. why?** A: Are you sure you ordered this from us - E.B. Atmus? There is plenty of stock in N. Carolina, so there would be no reason for you to have to wait a month. I don't have enough information about your order to know if you are asking the right company. If ordered today it should ship today and depending on where you are located take 2-5 days to get to you. **Q: Do these come in paires or single? Thanks** A: They come as singles. You would need to order two. **Q: There are two answers to the question "do they come in singles or in pairs" . (1)they come in singles, order two (2) comes in pairs Which is it?** A: Here is the review I wrote in 2012, when I ordered and received one gear: First, I was delighted to find that Amazon had this gear, with free shipping. This sort of thing is not sold at the local hardware store and I had expected to be charged for UPS shipping from an industrial supply house. The gear was a perfect mate to the older L99Y gear on my machine vise. (I had found an old, but unfinished product that had never had the second gear installed.) The new gear did not have a locking hole in the hub, so I drilled and tapped for a set screw. This was another good experience with Amazon. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/124609964-boston-gear-l112y-miter-gear-1-1-ratio-20-degree](https://www.desertcart.us/products/124609964-boston-gear-l112y-miter-gear-1-1-ratio-20-degree) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-28*
