The Bonvario BL series worm gearbox is made of high-quality materials to ensure maximum reliability and strength, thereby extending the service life of the gearbox. The worm is made of steel and undergoes surface hardening treatment, with a hardness of 58-60 HRC and formed grinding. In the allowable gear ratio of the modulus, thread grinding adopts the ZI type, which improves the contact between the tooth surfaces, thereby improving the performance of the gearbox. It also reduces the operating noise of the gearbox. The worm wheel adopts the G20 cast iron wheel hub, and the hub is equipped with an AS 1 bronze ring cast component. The gearbox housing and flange of this series are made of aluminum alloy, with a maximum size of 90. All sizes of this series of gearboxes have universal installation options. The gearboxes below 90 use ISO VG 320 synthetic oil, which requires almost no maintenance and does not need to be changed during its service life. Gearboxes with specifications of 63 and above are equipped with two tapered roller bearings on the worm shaft to increase the mechanical resistance to the axial thrust generated by the worm wheel.

The Worm Reducer-Replacement of Bonvario BL Series Worm Gearbox Size 30 is a high-quality replacement part manufactured by Raydafon. Our products are of good quality and competitive price. It is important to note that our products are replacement parts and not original parts. If you need original parts, please contact the original supplier for purchase.


The working principle of Worm Reducer-Replacement of Bonvario BL Series Worm Gearbox Size 30 is that the worm on the input shaft drives the worm wheel on the output shaft to rotate, and then the output shaft realizes the deceleration effect. The worm gear reducer has a large ratio of transmission, a smooth transmission, and a stable operation. It can be used for forward and reverse transmission and has self-locking function.


Our Raydafon brand provides high-quality replacement of Bonvario Worm Gear Unit. Our products have the following advantages:
