FAQ Question?What is the recommended tightening torque for the M6 screws on the TLK450 40×65? Question?The manufacturer specifies a tightening torque (Ms) of 17 Nm for the M6 screws on this model. It is crucial to use a calibrated torque wrench and follow a criss-cross pattern for even pressure. Question?Can the Tollok TLK450 be used in an oily environment? Question?Yes, but the transmittable torque values are based on clean, dry, and grease-free contact surfaces (shaft and hub bore). If oil or grease is present, the transmittable torque will be reduced. Ensure all surfaces are thoroughly degreased before installation for optimal performance. Question?Is this TLK450 locking assembly self-centering? Question?The Tollok TLK450 series is a self-centering design. This feature ensures excellent concentricity between the hub and the shaft, which is critical for high-speed applications to minimize vibration.
