This 5-hole Round-End Pattern Plate is made of 2.5mm thick aluminum - striking a great balance between weight and strength. The 16mm goBILDA pattern, which has been slotted to 24mm across center, repeats down the length of the plate providing many mounting options. The 14mm holes can be used for 14mm OD bearings as well as parts which contain a 14mm protrusion (like hubs) to ensure concentricity. The 32mm width makes for a more compact option when compared to 1123 Series Pattern Plates. The rounded shape provides added clearance for nearby rotating components.
