Industrial gearboxes

Long-term technical experience and top products
NSK – the world's leading supplier to manufacturers of all types of gearboxes
Close cooperation with experienced technicians from the represented manufacturers
Individual customer support during development of new products, and help solving complicated problems

Our warehouses and those of our suppliers contain a wide range of bearings.

Our range of gearbox types is constantly expanding, with different sizes and functions, as well as gearboxes designed for various complex conditions. When selecting a suitable bearing type, we always take into account the special operating conditions at the bearing’s destination:

Full-complement cylindrical roller bearing for low speed and high radial loads
Spherical roller bearings for very high loads and components in oblique arrangement
Cylindrical roller bearings for high speed and high loads, functioning as a floating bearing
Four-point bearing, acting as the locating bearing for the high-speed stage, while the cylindrical roller bearing takes the radial load

We offer an innovative TF bearing series made from special bearing steel, offering a significantly extended bearing life, especially in contaminated environments.

We supply various designs of metric and inch, tapered roller bearings. Our special bearings for demanding conditions combine long service life with an excellent resistance to humidity and contaminated environments.

HPS spherical roller bearings feature a progressive, optimised internal design and special tough materials, doubling operating life in comparison to conventional products.

EM/EW cyllindrical roller bearings, with a larger number of rollers than standard types, achieve higher load capacity and excellent performance in vibration devices.

Spherical roller bearings made of special TF steels and CAM cages
Taper roller bearings made of special TF steels
Bearings with special anticorrosive coating

Benefits of innovated bearings

Extremely tough, with crack resistance
Higher load capacity
Low noise
Higher resistance
Extended bearing life
Reduced maintenance costs

Example of solving bearings defects in a wind turbine gearboxes

Fail description: Cracking - White etching crack (WEC). Flaking - White Structure Flaking (WCF). The appearance of white cracks on the surface of rings and raceways, but also deep inside the material, white structure flaking.

Target: Eliminate this defect and achieve a wind turbine gearbox lifetime of 20 years

Solution: Newly developed material AWS-TF

(High purity material + special heat treatment + residual austenite control)

A new bearing steel was developed, which has a homogeneous structure that significantly reduces cracking. The material tougness was improved by applying a new heat treatment and a special coating was used for even greater protection against external influences. As a result, the lifetime of wind turbine gearbox is up to seven times longer. Check out the AWS-TF Brochure.
