These design features help in meeting these critical application requirements and help in achieving higher service life & reliability.
A Typical Manual Transmission
Transmissions help convert the power supplied by the Engine into usable toque. Based on the Pass Car type, various gearbox variants are used – Manual, Transaxle, Dual Clutch Transmission, E gearboxes, PHEV, Hybrids, etc. Following critical positions are present in these applications
- Input Shaft/Counter Shaft
- Differential Shaft
- Gear Blanks
The critical application requirements of bearings –
- High Speeds for E gearboxes
- Lesser Bearing Envelopes
- Contaminated operating conditions
- High Static Loading
- Shafts with high aspect ratios
- Higher component/system reliability
- Higher Service life
NBC Engine Bearing Solutions:
Following specialized features offers cater to application specific requirements:
- lower friction & NVH solutions
