It combines an 8mm **R**ound profile with a 7mm h**EX** to provide the best of both worlds: you can use it with 8mm round bore bearings and spacers, while simultaneously achieving positive drive with 8mm REX™ bore motion components throughout the build system—such as hubs (like those included in this Pack), as well as gears, wheels, sprockets, and pulleys (purchasable separately). ### Bundle Contents: | SKU | Qty | Name | |---|---|---| | [1309-0016-4008](https://core-electronics.com.au/1309-series-sonic-hub-8mm-rex-bore.html) | 4 | 1309 Series Sonic Hub (8mm REX™ Bore) | | [1310-0016-4008](https://core-electronics.com.au/1310-series-hyper-hub-8mm-rex-bore.html) | 4 | 1310 Series Hyper Hub (8mm REX™ Bore) | | [1522-0010-0020](https://core-electronics.com.au/1522-series-8mm-id-spacer-10mm-od-2mm-length-4-pack.html) | 1 | 1522 Series 8mm ID Spacer (10mm OD, 2mm Length) - 4 Pack | | [1522-0010-0040](https://core-electronics.com.au/1522-series-8mm-id-spacer-10mm-od-4mm-length-4-pack.html) | 1 | 1522 Series 8mm ID Spacer (10mm OD, 4mm Length) - 4 Pack | | [1522-0010-0060](https://core-electronics.com.au/1522-series-8mm-id-spacer-10mm-od-6mm-length-4-pack.html) | 1 | 1522 Series 8mm ID Spacer (10mm OD, 6mm Length) - 4 Pack | | [1522-0010-0080](https://core-electronics.com.au/gobilda-1522-series-8mm-id-spacer-10mm-od-8mm-length-4-pack.html) | 1 | 1522 Series 8mm ID Spacer (10mm OD, 8mm Length) - 4 Pack | | [1522-0010-0120](https://core-electronics.com.au/1522-series-8mm-id-spacer-10mm-od-12mm-length-4-pack.html) | 4 | 1522 Series 8mm ID Spacer (10mm OD, 12mm Length) - 4 Pack | | [1611-0514-4008](https://core-electronics.com.au/1611-series-flanged-ball-bearing-8mm-rex-id-x-14mm-od-5mm-thickness-2-pack.html) | 8 | 1611 Series Flanged Ball Bearing (8mm REX™ ID x 14mm OD, 5mm Thickness) - 2 Pack | | [2106-4008-0540](https://core-electronics.com.au/2106-series-stainless-steel-rex-shaft-8mm-diameter-54mm-length.html) | 1 | 8mm REX™ Shaft with E-Clip (Stainless Steel, 54mm Length) | | [2106-4008-0640](https://core-electronics.com.au/2106-series-stainless-steel-rex-shaft-8mm-diameter-64mm-length.html) | 2 | 8mm REX™ Shaft with E-Clip (Stainless Steel, 64mm Length) | | [2106-4008-0800](https://core-electronics.com.au/2106-series-stainless-steel-rex-shaft-8mm-diameter-80mm-length.html) | 2 | 8mm REX™ Shaft with E-Clip (Stainless Steel, 80mm Length) | | [2106-4008-0960](https://core-electronics.com.au/2106-series-stainless-steel-rex-shaft-8mm-diameter-96mm-length.html) | 2 | 8mm REX™ Shaft with E-Clip (Stainless Steel, 96mm Length) | | [2106-4008-1200](https://core-electronics.com.au/2106-series-stainless-steel-rex-shaft-8mm-diameter-120mm-length.html) | 2 | 8mm REX™ Shaft with E-Clip (Stainless Steel, 120mm Length) | | [2106-4008-1920](https://core-electronics.com.au/2106-series-stainless-steel-rex-shaft-8mm-diameter-192mm-length.html) | 1 | 8mm REX™ Shaft with E-Clip (Stainless Steel, 192mm Length) | | [2800-0004-0012](https://core-electronics.com.au/2800-series-zinc-plated-steel-socket-head-screw-m4-x-07mm-12mm-length-25-pack.html) | 1 | M4 x 0.7mm Zinc-Plated Socket Head Screw (12mm Length) - 25 Pack | | [2801-0004-0011](https://core-electronics.com.au/2801-series-zinc-plated-steel-washer-4mm-id-x-11mm-od-25-pack.html) | 1 | 2801 Series Zinc-Plated Steel Washer (4mm ID x 11mm OD) - 25 Pack | | [2807-0811-0500](https://core-electronics.com.au/2807-series-stainless-steel-shim-8mm-id-x-11mm-od-050mm-thickness-12-pack.html) | 1 | 8mm ID Stainless Steel Shim (11mm OD, 0.50mm Thickness) - 12 Pack | | [2910-0920-4008](https://core-electronics.com.au/2910-series-aluminum-clamping-collar-8mm-rex-id-x-20mm-od-9mm-length.html) | 2 | 2910 Series Aluminum Clamping Collar (8mm REX™ ID x 20mm OD, 9mm Length) | | [4007-4008-4008](https://core-electronics.com.au/4007-series-hyper-coupler-8mm-rex-bore-to-8mm-rex-bore.html) | 1 | 4007 Series Hyper Coupler (8mm REX™ Bore to 8mm REX™ Bore) | | [5027104001](https://core-electronics.com.au/wera-tools-3mm-ball-end-hex-plus-l-key.html) | 1 | Wera Tools 3mm Ball End Hex-Plus L-Key | ### Downloads - [ STEP File ](https://core-electronics.com.au/attachments/localcontent/3201-0008-0001_6251151174d.zip) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/G/B/GB-3201-0008-0001-1.jpg)
