Bevel Gear Boxes Housing Aluminum * Deviating from DIN 6885 ** Theoretically usable hub diameter -- Aluminum -- Sealed to prevent dust entry -- Anodized, natural color AN Information Bevel gear boxes GN 3971 can transmit high torque despite their very compact dimensions. They can readily be used for a multitude of applications, such as height adjustments or to change the direction of shaft rotation. The numerous fastening holes allow for simple mounting in any orientation or position. The parallel keys can take any angular positions. see also... • Worm Gear Reducers GN 3975 → Page 4 gear...
