## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-1519-0014-0400:1` (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-1519-0014-0400:1.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

Turn the open end of a 4103 Series tube into a bolt-on flange, and axially constrain it in a motion assembly without machining a thing. Four M4 screws into the end of the tube is all it takes.

Tubing that creeps through its own bearing is a familiar headache. At 36mm outer diameter, this endcap is sized to contact the inner race of a 32mm bore bearing, so the tube is positively constrained rather than free to wander.

Made from acetal(Delrin), each cap adds only 4.2g to a rotating assembly. Eight Ø4mm clearance holes across 16mm and 24mm spacings let you index the cap to whichever pattern lines up, and the 14mm central bore leaves room for a shaft or fastener to pass straight through.

At just 4mm thick, it stays compact enough to fit and rotate inside 1120 Series U-Channel, and pairing it with a 1505 Series Counterbored Pattern Spacer reverses the direction of constraint when you need it the other way around.

### Features

- Adds only 4.2g per cap to a rotating assembly, thanks to lightweight acetal construction
- 36mm outer diameter contacts the inner race of a 32mm bore bearing, giving the tube a positive axial stop
- Eight Ø4mm holes across two spacings give you multiple indexing options when bolting to the tube end
- 4mm profile fits and rotates inside 1120 Series U-Channel, so it suits tight internal assemblies
- Combines with a 1505 Series Counterbored Pattern Spacer to constrain the tube in the opposite direction
- Genuine goBILDA part, so it lands exactly on the system's M4 hardware, 32mm bearings and pillow blocks
