Center nut for hub AL-KO 1637/2051

Product detailed description

• Central self-locking nut for wheel unit hubs AL-KO 1637 and AL-KO 2051 with double row ball bearing
• The nut is designed for one-time assembly. A new nut must be used after disassembly. When the nut is reused, sufficient securing of the hub is not guaranteed.
• The prescribed tightening torque of 280 - 300 Nm must be observed. Incorrect tightening torque can result in bearing damage or hub loosening.
• Tightening the nut to the specified tightening torque automatically defines the clearance of the double row hub bearing.
• The nut is not intended for hubs AL-KO equipped with two tapered roller bearings or hubs from other manufacturers.
• We recommend that the installation be entrusted to a trained AL-KO service center.
