## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-2319-4008-0030:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-2319-4008-0030:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This 8mm REX™ bore 2319 Series Miter Gear is designed to mesh with another 2319 Series Miter Gear while achieving positive drive on 8mm REX™ shafting.

A miter gear is a specific type of bevel gear. When meshed together, a pair of miter gears creates a 1:1 ratio and transmits power at a 90 degree angle due to the 45 degree pitch cone angle.

### Engineered for High-Torque Applications

The 2319 Series Miter Gears are specially designed to maximize performance in high-torque applications. The large teeth extend the length of the gear to increase the area of the gear-to-gear mesh, and the long length of the “barrel” bore provides for maximal gear-to-shaft contact. Both qualities result in highly precise, no-slip rotation on a shaft.

Set-screws are absent in favor of a simple slip-fit installation. The underneath side of the gear is strategically designed so that when you space the gear 1.5mm from the inside wall of 1120 Series U-Channel (or any 43mm wide structure), the gears will mesh perfectly. In that vein, it’s convenient that a 1611 Series Flanged Ball Bearing protrudes 1.5mm into channel when installed on the outside. Alternatively, you can install the bearing on the inside—and still achieve the same 1.5mm distance—by installing a 0.5mm thick shim between the gear and bearing.

### Titanium Nitride Finish

A titanium nitride finish provides high-grade, low-friction material performance in tandem with the gear’s already robust steel construction. Titanium nitride is the same finish commonly found on heavy-duty equipment like drill bits; as such, this gear’s resistance to wear is off-the-charts!
