R Series Inline Helical Geared Motor

Tunsing Transmission

R Series Inline Helical Geared Motor

Tunsing’s R series uses helical gearing in an inline gearmotor arrangement. Its company-hosted illustrated catalog lists foot and flange mounting, solid-shaft output and combinatorial drive variants. On the official R-series selection table, the R37 column shows an input-power range of 0.18 to 3 kW and 200 Nm permissible torque. The page also diagrams mounting positions M1 through M6 and terminal-box rotations of 0, 90, 180 and 270 degrees. These are configuration options, not performance guarantees for every motor choice. For a comparison, specify the intended R frame, ratio, input motor, output shaft and service load, then confirm the exact table cell and drawing with the maker.

FF Parallel-Shaft Helical Geared Motor

Xinghai Reducer

FF Parallel-Shaft Helical Geared Motor

Xinghai’s FF series is a parallel-shaft helical geared motor designed for installations where an inline drive would occupy too much length. The official page lists foot, flange and shaft-mounted arrangements, a headline output-speed envelope of 0.1 to 752 rpm, and up to 12,000 Nm output torque. It also gives a motor-power envelope of 0.12 to 90 kW. A frame table spans multiple sizes and mounting structures; its row values must be checked individually because the fastest speed, highest torque and largest motor do not describe a single gearbox. Gear material and processing are described as alloy steel with carburizing, hardening and tooth grinding. Confirm the selected FF frame, input motor and service factor with Xinghai.

R Series Inline Helical Geared Motor

Feluoka Heavy Industry Transmission

R Series Inline Helical Geared Motor

The Feluoka R series uses an inline helical arrangement rather than the K series’ right-angle helical-bevel path. On its official page, the maker lists rated output torque of 130 to 18,000 Nm across the series, motor power of 0.12 to 160 kW at 1,400 rpm input, and ratios from 3.37 to 229.71. The family supports foot or flange mounting and IEC or servo motor interfaces. As with any broad series range, the upper torque, power and ratio belong to different possible configurations unless a frame-specific selection confirms otherwise. Buyers should compare the output speed, thermal duty, mounting dimensions and service factor for their actual R-frame order.

JCR Helical Geared Motors

Jiacheng / Chen Chao

JCR Helical Geared Motors

JCR is Jiacheng’s modular helical geared-motor family. The source lists models 37–177, ratios from 3.77 to 267.77 and an input-power envelope from 0.12 to 250 kW. Its published output-torque range spans 3.5–56,845 Nm across the family. The manufacturer describes an integral cast housing and use in frequent starting or reversing duties; an application still needs a service-factor and thermal check. Provide the load cycle, motor requirements and mounting arrangement so the supplier can confirm a complete combination. Do not combine the largest torque and highest ratio into an assumed standard unit.

TR Hardened-Tooth Helical Reducers

TONGLI

TR Hardened-Tooth Helical Reducers

The TR family uses helical gearing for compact industrial speed reduction. TONGLI lists TR18 through TR188 frame designations and a ratio envelope from 3.37 to 289.74. Its 50,000 Nm maximum is the top of the series, not the torque available from every frame or at the highest ratio. The published output-speed and motor-power envelopes also span multiple configurations. This range is intended for machinery such as conveying and mixing equipment. Ask TONGLI to select the complete frame, motor, reduction stages and service factor from your actual load cycle before comparing quotations.

WR Inline Helical Gear Reducers

WUMA

WR Inline Helical Gear Reducers

WR is an inline helical-reducer range with two- and three-stage gear trains. WUMA lists HT250 cast iron for the housing and foot, shaft and flange installation options. The source identifies thirteen frame designations and a family efficiency envelope of 94–98%, rather than a single efficiency valid at every load. WR and the newer modular MR range are separately named by the manufacturer; this page documents WR only. For replacement work, compare the complete mounting drawing and motor connection, then ask for a model-specific ratio and torque rating at the intended input speed.

RX Single-Stage Helical Gear Units

SEW-EURODRIVE Tianjin

RX Single-Stage Helical Gear Units

Single-stage RX helical gear units in six sizes. The low-ratio range is suited to higher output speeds. Published maximum torque is a frame-dependent envelope, not the rating of every size.

MTH Heavy-Duty Helical Gearbox

TANHON

MTH Heavy-Duty Helical Gearbox

Heavy-duty helical gearbox family with horizontal and vertical arrangements. Power, output speed and torque envelopes span multiple sizes and stages; they must not be combined into an assumed configuration.

ER Helical Geared Reducers

EVERGEAR

ER Helical Geared Reducers

Coaxial helical reducer family with foot and flange mounting. These specifications follow the current Chinese ER product page; confirm a model-specific selection before using the maximum output torque in a design.

H / B Industrial Gearboxes

Boneng

H / B Industrial Gearboxes

Modular helical and bevel-helical gearboxes for industrial drives. H and B have different ratio and power envelopes; size, mounting, thermal capacity and service factor determine the final selection.
