Varvel continues to score successes in its product range completion with the new hollow output shaft speed reducers 'Series RN-RO-RV'.
Each size of this new series - displayed at the former Hannover Fair, April 2007 - is designed with a common base body that gives rise to three different speed reducer lines by the means of the appropriate input module fitting: RN shaft mount, RO horizontal and RV vertical input bevel/helical.
Speed reducers are designed in six sizes - aluminium pressure die cast for the smallest three and grey cast iron for the bigger ones - with 30 reduction ratios in two and three stages, and output torques from 180 Nm to 3200 Nm.
Multiple foot-, flange- or torque arm mountings are available as well as hollow output shafts (keyed, shrink-disk, splined) and solid simple or double sided.
Same fixing footprint for the three versions, high flexibility, easy mounting and quick lead times are the pluses that make the speed reducers RN-RO-RV a really new and advanced range.

The Anglgear,the original right angle drive, is widely recognized and is in use worldwide. The Anglgear provides manual or power transmission of rotary motion in a compact, standardized right angle unit.
Our standard line of bevel gearboxes are available from stock in both an Inch and Metric Series, single or dual output shafts, 1:1 or 2:1 ratios, are grease lubricated for life and have an operating temperature range of -65 degrees F to + 200 degrees F ( -54degrees C to + 93degrees C). Utilizing carburized case-hardened Coniflex* bevel gears, all AnglGear units employ completely enclosed & sealed ball bearings.
The cast aluminum housings are precision machined, on our CNC machining center and then coated with a chemical film to protect the material, and use flanged ends and side bosses for compact installation in a wide range of applications.
The shaft material used for sizes 1,2,and 3 is # 416 stainless steel. On the 2:1 models, the pinion shaft is carbon steel. For the sizes 4 & 5, the material is black oxide carbon steel. Shafts can be provided with special extensions ( with flats, splines, holes,etc.) and /or specific lengths upon request.
In addition to our standard models, we will modify our units to meet your design specifications! Our sales and engineering departments are ready to assist you with your specific application requirements.
