Development of New Steering Wheel Locking Mechanism for improved Safety during Automobile Collisions
This new technology could certainly makes a difference in personal safety during car crash. Conventionally, the steering system in the vehicle is responsible to translate the movement of the steering wheel to the wheels in terms of steering angle and force as the driver turns the steering wheel to turn his/her vehicle in the desired direction. In addition to this the steering system provides drivers with the mean of adjusting the steering wheel to the desired position in their vehicle. Furthermore, during collision, the steering column has been designed to collapse in order to soften its impact on the driver, in addition to introduction of airbags and seatbelts. Normally, the steering column which houses the driver’s airbag is required to sustain a strong impact, without moving up and down, as its airbag is deployed. Conventional steering column locking mechanism normally employs a multi-plate method which involves the layering of multiple steel plates to create friction in order to lock the steering wheel in place, however at the unlocked position this method does not provide enough clearance between the steel plates resulting in undesirable operation of steering system.

Development of a New Ball Bearings resulting in More Compact Automotive Transmissions
NSK has announced the development of a new ultra-long-life ball bearing for automotive transmission system. The new design makes the bearings more compact and lightweight, with less friction, hence contributing to reduction of automotive transmission size and weight and greater fuel efficiency. Read more
Release of Cage-Equipped Thrust Ball Bearing in Hydraulic Static Transmission for Agricultural Machinery
NSK has rolled out a new high-performance and longevity cage-equipped thrust bearing, designed for hydraulic static transmission (HST) in agricultural machinery. The new NSK bearing uses EP steel in outer and inner races due to its strength against sub-surface fatigue. In addition to this, NSK applies a special heat treatment, which also adds resistance to surface fatigue, for the inner as well as outer races and balls. Read more
Development of Silent Bearing for Automotive Electric Motors by NSK
In an effort to make automotive engine quieter, NSK has introduced a long-lasting silent bearing for automotive engine through use of improved lubrication performance and noise control and sound isolation technology. NSK new bearings remains silent for an extended period of time at a high temperature through use of newly developed grease in addition to conventional noise damping technique based on optimization of internal design.

The new Ball bearing offers an improved axial load carrying capacity from 1.1 to 2.8 times with smaller size and longer service life. Read more
Development of High-Precision Angular Contact Ball Bearings for Machine Tool Application by NSK
NSK has released of small-bore, angular contact ball bearings with seals which has been designed specifically for use in the main spindles of machine tools. The new angular contact ball bearings have an inner diameter of 6 to 25 mm. The new product incorporates specially designed non-contact seals plus a low vibration cage. Read more
Development of New Roller Guide with High Performance Side Seals by NSK
Roller guides offers both high rigidity and large load capacity, making them ideal for such application as machine tools used in production environments. The currently used roller guides are susceptible to fine dust particles that can find their way into roller guide slider causing abnormal abrasion of the raceway, resulting in impairment of the rotation of the rolling element. While conventional roller guides are enclosed in covers to prevent penetration of dust particles, the covers fail to completely stop particle penetration. In response to this, NSK has developed a new roller guide which is equipped with high performance side seals, featuring durability under harsh operating conditions where the lubrication tends to dry out or become contaminated by dust.
