Rolling bearings normally comprise bearing rings, rolling elements and a cage.
Rolling elements are arranged between inner and outer rings with a cage, which retains the rolling elements in correct relative position, so they do not touch one another. With this structure, a smooth rolling motion is realized during operation.
There are many types of bearings such as Deep Groove Ball Bearing, Angular Contact Ball Bearing, Cylindrical Roller Bearing, Spherical Roller Bearing, Tapered Roller Bearing, Thrust Ball Bearing, Needle Roller Bearing and etc.
A drive shaft acts as an intermediate between a driving shaft and driven shaft that are not aligned on the same axis, and transfer running torque smoothly.
A drive shaft has two universal joints, enabling a flexible connection between a driving shaft and driven shaft. Each universal joint (cross bearing) has four rolling bearings, realizing low friction and minimizing torque losses.
Oil seals work to prevent leakage of sealed objects such as lubricants from inside and also to prevent the entry of dust and contaminants from outside.
- Lightweight, compact, and energy-saving
- High sealing performance by optimum lip design
- Low heat generation and long service life by highly self-lubricating rubber materials.
- High sealing performance and long service life by hydrodynamic ribs (Perfect Seal, Helix Seal, Super Helix Seal)
