Manual Transmission
Overview
Manual transmissions must adequately meet driver expectations of control by conveying a smooth, precise, and crisp feeling. Transmissions must also be compact, lightweight, and be able to deliver excellent fuel efficiency for the increased number of gears that are appearing in newer vehicles. The bearings and synchronized parts created by NSK play a key role in supporting the future of manual transmissions with their unsurpassed reliability and capability developed with tribology technology.
Products
Long life has been achieved by specially designed seals for transmissions. The seals prevent ingress of contaminants in the oil. Size reductions from standard open type bearings can be achieved.
High capacity cylindrical roller bearings for radial load, as well as axial load from gear meshing.
Superior roller stability after assembling the cup and the cone achieves quick and high precision preload setting. The set preload is maintained at higher levels for longer periods.
Smooth rotation and sliding have been achieved in a compact size.
Reduced weight and costs have been achieved by using of plastic cages with superior oil and heat resistance.
Best for preventing fretting generated at the time of non-relative rotation between gear and shaft.
Self-centering clutch release bearings with reduced weight and costs have been achieved by reducing the number of parts combined with press technology.
Reduced costs have been achieved by using original material that allows for press forming and through hardening. Superior friction characteristics from precision taper surface processing technology contribute to smoother shifting.
