Search by product type

Deep Groove Ball BearingsThis is the most commonly used ball bearing. It simultaneously receives radial and axial load.
Angular Contact Ball BearingsSuitable for applications requiring high accuracy and high rotational speed. It receives a radial and axial combined load.
Special Environment Ball BearingsA high performance bearing series strong in special environments such as clean/vacuum/high-temperature and corrosive environments.
Thrust Ball BearingsAvailable in single type and double type, the single type thrust ball bearing receives unidirectional axial load, while the double type receives bi-directional axial load.
Self-Aligning Ball BearingsThis bearing self-aligns to correct misalignment between the axis and housing centers, axis deflection, etc. by a tilt of its inner ring, balls and cage.
Spherical Roller BearingsThis bearing has an aligning property to allow for housing deflection and center displacement, and is suitable for applications at low/medium speed which involve heavy load and impact.
Tapered Roller Bearingshe tapered shape enables a long line contact, making this bearing suitable for applications with heavy load and impact load.
Cylindrical Roller BearingsThere is line contact between the rollers and raceway, therefore radial load capability is high, making this bearing superior in regards to its ability to withstand heavy loads and impact loads.
Needle Roller BearingsDue to its small cross-sectional height, this bearing helps keep machines lightweight and compact and is widely adopted across all fields.
Oil SealsContributing to weight reduction, size reduction and resource-saving, this oil seal offers excellent sealing performance due to an optimal lip structure. It is also low-heat generating and long-life.
