Single row radial ball bearings are the most widely used bearings and utilize an uninterrupted raceway, which makes these bearings suitable for radial loads, or a combination of thrust and radial loads. This design permits precision tolerances even at high speed operation. Shielded bearings are protected on one, or both sides (suffixes Z and ZZ, respectively) by metal shields fastened to the outer ring. This close clearance labyrinth seal retains the lubricant and prevents the entrance of foreign matter. Sealed bearings incorporate steel reinforced rubber seals securely fastened to a groove on the outer ring. Contact with the inner ring is by sealing lip (Contact Suffix LLU). Or, non-contact with the inner ring is by labyrinth seal (Non-contact Suffix LLB) to provide positive sealing at all times.
NTN is one of the three largest bearing companies in the world with more than ninety years of manufacturing expertise in ball bearings.
1.Details about deep groove ball bearing
Open Deep Groove Ball Bearings: One of the most commonly used bearings, the open types are manufactured without seals to allow for the free circulation of either oil or grease, used in gearboxes and other environments where no foreign matter would be present and a lubricant supply is available.
Metal Shielded Deep Groove Ball Bearings: One of the most commonly used bearings, these types are manufactured with metal shields inserted into the outer raceway, these fit in closely to the inner race providing protection against light mechanical damage, some protection against the ingress of moisture, dust and other foreign matter and serve to retain the pre-filled grease in the bearing. Shields can be easily removed for applications that only require 1 shield
2.NTN Bearing Features:
1. Deep groove geometry for high speeds
2. Single row for supporting radial loads
3. Steel cage evenly spaces balls for reduced friction, vibration and noise
4. Rubber seal on the side of the bearing exposed to contaminants and open on the other for applying lubricant
5. CN (normal) radial internal clearance for applications that do not involve thermal expansion or atypical precision
