STM STANDARD PRODUCTS

Standard Gearboxes and Geared Motors, thanks to their flexibility in application, are the solutions which ensure the best value for money.

worm gearboxes

WORM GEARBOXES

Worm gearboxes have been the first products of STM S.p.A. and they have been recently updated. 

All aluminium components are die casted (from size 28 to size 110) to increase resistance to torsional and structure flexibility.

 ZI teething profile (section and involute) has been adopted to increase efficiency and silentness and, finally, a modular attachable output flange (FL, FA, and FB) has been adopted to increase flexibility.

Worm gearboxes R, universal worm gearboxes U,
double worm gearboxes RR, helical worm gearboxes
CR ensure high efficiency, longevity and the highest
transmittable torque: the compromise cost/performances is particularly centered in the middle range reduction ratios.

Mechanical speed variators

MECHANICAL SPEED VARIATORS

STM Mechanical speed variators WMF are characterised by the integral motor flange to the housing and by the completely modular structure for the output flange and the feet.

These features allow to reduce the dimensions and the stock warehouse improving and increasing the flexibility and overall economicity.

Right angle gearboxes

RIGHT ANGLE GEARBOXES

Right angle gearboxes Z are characterised by one body piece in cast iron with all the external faces machined, their gears are Gleason and their bearings are overrated as well.

Aluminium right angle gearboxes ZL have a strong one house piece in aluminium.

Both gearbox series ensure a favourable relationship
between power and dimension and a silent and regular working, also at high speed.

STM HIGH TECH PRODUCTS

High Tech Gearboxes and Geared Motors are designed to provide the best results in those applications requiring top performance in continual use. High Tech Gearboxes: when durability is the best
solution.

Inline gearboxes

INLINE GEARBOXES

STM Inline gearboxes and geared motors are based on one body piece casting giving increased rigidity. 

This allows the application of high loads without risks of deformation which might negatively affect technical performances.

The particular internal shape of the body directs the oil flow in a way to reach all moving parts while reducing noise levels and improving sealing tightness.

Another new feature is the modular output flange that allows a great versatility of application. Single stage inline gearboxes A/1 ensure the right ratio between torque and price for industrial applications where a high number of revolutions is
required on the output shaft.

parallel gearboxes

PARALLEL GEARBOXES

Parallel gearboxes are extremely robust due to the single piece, cast housing, which, combined with the possibility to have both direct compact PAM and PAM with bell housing and elastic coupling

This places the product at the high-end of the market in terms of quality and performance.

Parallel shaft mounted gearboxes P, universal parallel gearboxes RXP 700 and high torque parallel gearboxes with long center distance RXP 800 are an effective response to the power transmission needs of medium-heavy and heavy industry

Having adequate sizing which ensures constant and optimum reliability in the toughest working conditions.

shaft mounted gearboxes

SHAFT MOUNTED GEARBOXES

The sturdy shaft mounted gearboxes and geared
motors are extremely robust due to the monolithic
casing with inspection cover.

They are ideal for the material handling industry,
especially for the quarry and mine applications.

Shaft mounted gearboxes PT, parallel shaft mounted
gearboxes P and parallel shaft mounted gearboxes
with long center distance PL ensure absolute reliability and low maintenance.

BEVEL HELICAL GEARBOXES

BEVEL HELICAL GEARBOXES

Bevel helical gearboxes and geared motors are
extremely robust due to the single piece, cast housing, which, combined with the technical choice to have two and three stages reduction ratios.

This places the product at the high-end of the market in terms of quality and performance.

These gearboxes ensure an effective response to the
power transmission needs of medium-heavy and
heavy industry, having adequate sizing which ensures constant and optimum reliability in the toughest working conditions.

Bevel helical gearboxes O, skew bevel helical gearboxes SM, universal bevel helical gearboxes RXO/700, high torque bevel helical gearboxes RXO/800, cooling tower gearboxes RXO/TR, bucket elevator gearboxes RXO-O 800, extruder gearboxes RXO-V-EST 700-800, mining gearboxes RXMaster, GSMoveRX and GSMineRX have been designed to be used in a wide range of applications.

PLANETARY GEARBOXES

PLANETARY GEARBOXES

Planetary gearboxes and geared motors are compact, and yet extremely powerful.

Their planetary drive train makes them the ideal choice for all the severe duty applications where shock loadings and impacts are more the rule than the exception.

Product configuration is highly versatile, due to
several options as far as the mounting, the gear layout, the output shaft and the motor interface.

Planetary gearboxes EX, high torque planetary gearboxes EX, bevel helical planetary gearboxes EXB and high torque bevel helical planetary gearboxes EXR grant power without compromise.
