INA ball bearings include INA angular contact ball bearings,INA double row angular contact ball bearings,INA-aligning ball bearings
INA angular contact ball bearings:
Single row angular contact ball bearings with solid inner and outer rings, and balls and nylon, steel or brass cage components of self-sustaining unit. Inner and outer ring raceways in the bearing of the axial offset each other. There are open and sealed bearings.Their self-aligning capability is very small. Many sizes of angular contact ball bearings are X-life design. These bearings are shown in the dimension table. X-life quality has improved bearing raceway shape and optimized surface. This allows the bearing fatigue limit load has been significantly improved. Life in the revised calculations, the value of life improved more than 50%. Thus, in certain applications, when necessary, use a smaller bearings.
INA double row angular contact ball bearings
Double row angular contact ball bearings inside and outside the ring by the entity, and the ball and by the polyamide, stamping steel or brass cage formed unit. Their structure with a pair of O shaped layout of the single row angular contact ball bearings are similar, but more compact. They have different sizes of the contact angle and the bearing ring design. Bearing can be open and sealed. As the production technology used, open bearingsThe outer ring for seals or dust cover on the cutting slot. Sealed bearings require no maintenance, especially for the economy bearing applications.
INA-aligning ball bearings:
Self-aligning ball bearing with a concave groove from the outer plate of the solid cylindrical or conical hole with inner and ball and cage assembly consisting of two-column retention unit. These bearings can be vented, there are enclosed.
