Helical Gearmotor R Series

Products

In six single-stage and fourteen two-stage
and three-stage sizes, the helical gearmotors by SEW-EURODRIVE ensure
an optimum ratio between power and space requirements.

Your advantages

High torque density

Long service life

R37 … R167 Reduced backlash option

RM series, specially designed for agitating applications

The tried and tested modular concept and our
strict quality criteria allow SEW-EURODRIVE to provide a diverse
range of torques and reduction ratios with incomparably finely tuned
gradings. With this exceptional diversity, SEW-EURODRIVE sets new
standards in the field of drive engineering.

Available versions

Single-stage or multi-stage

Foot-mounted or flange-mounted

Foot-mounted and flange-mounted

Flange-mounted with extended bearing hub

	RX series (single-stage)
	For high output speeds, the exclusively single-stage gear units RX57 to RX107 offer compact solutions for your system design.

Technical data
Gear unit reduction ratio	[i]	1.30 – 8.65
Output torque	[Nm] ([in-lb])	69 – 830 (610 – 7340)
Motor power range	[kW] ([Hp])	0.12 – 45 (0.16 to 60)

R
series (two-stage and three-stage)

Our complete range
of helical gearmotors provides the optimum size and power solution
for every drive task. And for applications where weight is an issue, our
multi-stage gear units provide something special: Thanks to their
die-cast aluminum design, the models R07, R17 and R27 are three
particularly efficient lightweights – ideal as satellite drives
and for use in light machine constructions. Reduced backlash helical
gear units are also available for particularly precise requirements.

Technical data
Gear unit reduction ratio	[i]	3.21 – 289.74
Multi-stage gear unit reduction ratio	[i]	90 – 27001
Output torque	[Nm] ([in-lb])	50 – 18000 (440 to 159300)
Motor power range	[kW] ([hp])	0.12 – 90 (0.16 to 120)

	RM series
	RM gearmotors with extended output bearing hub are a special type of helical gearmotor. They were designed especially for agitating applications and allow for high overhung and axial loads and bending moments. The remaining data corresponds to that of standard helical gearmotors.

Technical data
Gear unit reduction ratio	[i]	4.29 to 289.74
Multi-stage gear unit reduction ratio	[i]	134 to 27001
Output torque	[Nm] ([in-lb])	270 to 18000 (2380 to 159300)
Motor power range	[kW] ([hp])	0.12 to 160 (0.16 to 215)
