The textbook says: Gearboxes are systems for converting and translating motion. The designer says: bearings for industrial gearboxes are a means of supporting the torque and speeds of the drive end to the required turning moments and speeds of the engine – according to the individual and specific operating processes. And what does the engineer say from experience? Above all, bearings for modern industrial drive systems face the most demanding and most versatile requirements. Features, including sufficient availability, long life, economy and best combination features of weight and performance, are only a few examples out of many.

Just as versatile as their functions

To achieve the desired torque and speed, a certain degree of fatigue strength and life needs to be guaranteed for all components. In addition, sufficient cooling and noise levels need to be achieved for maximum performance. These features have always been fundamental for gear operation. Considering the various areas of application, the number of gear types is increasing, as are the demands for smooth gear operation.


For example, environmental conditions (such as contamination, water and shock loads) affect bearing performance, as do specific operation modes, such as stop-start mode or stand-by operation. The inherent operating requirements for precision gears, such as employed in press printing machines, vary from those employed in wind generator plants, which require a high degree of maintenance free operation.

FV BEARINGS FOR GEAR-BOX       



When selecting a suitable bearing type the special operating conditions at the respective bearing location is taken into consideration.


  1. Full complement cylindrical roller bearing for low speed and high radial loads.

  2. Spherical roller bearings for ultra-high loads and components in oblique arrangement.

  3. Cylindrical roller bearings for high speed and high loads, functioning as a floating bearing.

  4. Four-point bearing, acting as the locating bearing for the high speed stage, while the cylindrical roller bearing takes the radial load.


Hypoid bevel gears

The larger-sized pinion which is part of this hypoid 

bevel gear integrating an offset pinion shaft, 

facilitates lower peripheral force while the turning 

moment (torque) remains constant. The offset axis 

provides for higher strength of pinion support in both 

directions. Low noise generation is a further advantage. 

However, a disadvantage is increased friction due to 

additional sliding motion.

Worm gear

A particular advantage is translating motion in a single 

stage. In most cases the axis of worm and worm gear 

intersect below 90°, provided there is sufficiently high 

clearance between the axes. During operation vibration 

is absorbed to a high degree and noise generation 

during operation is low. However, the high friction 

reduces the degree of efficiency. This gear is usually 

employed in combination with a globoid gear with 

cylindrical worm made from steel, because these 

can be subjected to tempering and grinding.

Planet gear

Utilizing planetary wheels with internal gears, 

epicyclic gearboxes have significant advantages

over other gearbox types. Volume and weight are

reduced. Due to low rolling speed and low sliding

speed within the tooth system, noise generation

can also be reduced. An increased degree of efficiency

can be achieved due to the fact that part of the

energy is translated to the coupling performance – 

these advantages often compensate for increased 

maintenance.

Spur gear

Parallel axis gears generally fall into two main types – 

Spur gears and Helical gears. While spur gears have the 

advantage of ease of manufacture and accuracy, 

smooth operation and high load capacity are achieved 

through helical gears (albeit with the need to react the 

thrust loads). Double helical gears constitute a sub-type 

with increased load capacity and larger face width.

Bevel gear

There are three types of design depending on tooth 

traced characteristics. If spur gearing is used, tooth 

engagement cangenerate noise. Although Helical 

bevel gears also use straight tooth profiles, they 

have reduced noise levels, due to improved mesh 

characteristics. The third type of design employs 

spiral bevel gears and curved tooth bevel gears. This 

type of design operates at the lowest noise levels.

Gearbox is an important equipment in industry. The rotating gear is inseparable from the support of the bearing. High quality bearings can bring efficient power conversion to gearbox.
