Solid V-Wheel Bearing Kit for V-slot Aluminum Extrusion

From the shop's description

The Solid V-wheel kit can be used directly for linear motion sliding system with the V-slot rails. It is made for heavier loads as it has more resistance to deflection and deformation when load is applied. Many of these wheels could be added to a gantry to allow an even distribution of the load across them. Each wheel is carefully milled for consistent high precision and tolerance. kit Includes: Openbuilds Solid V wheels x 1 Ball bearings - 625 2RS X 2 5 mm precision shim x 2 Aluminum Spacer (M5 - 6mm) x 1 Lock nut with Nylon Insert x 1 Screw (M5 - 25mm )x 1
