BNR/BER Series Ultra-high Speed Sealed Angular Contact Ball Bearings

BNR BER Ultra High Speed Sealed Angular Contact Ball Bearings

BNR/BER series ultra high speed sealed angular contact ball bearings are add with dust-proof seals, sealing rings on the outer ring to prevent dust, dirt, and other pollutants entering the bearing, effectively reducing the impact of pollutants on bearing performance, extending bearing service life, and reducing maintenance costs. This series is BNR/BER29 and 20 sealing series, with two contact angles of 18 ° (BNR) and 25 ° (BER). The ball materials include steel balls (S), ultra long life bearing rolling elements (E), and ceramic balls (H, X). The cage includes four types: outer ring guided phenolic resin cage (T), outer ring guided PPS resin cage (TSR), and rolling element guided polyamide resin cage (TYN). Due to the sealing structure design, the lubricant inside the bearing can maintain cleanliness for a long time, reduce friction and wear, and improve rotational accuracy. This design is widely used in high-precision mechanical equipment.

The adoption of non-contact sealing structure in BNR/BER series ultra high speed sealed angular contact ball bearings does not significantly affect the high-speed performance of the bearings, and can also maintain stable operation under high-speed rotation. This feature makes it widely used in high-speed motors, turbochargers and other equipment. This series adopts a pre lubrication design, which does not require additional lubrication during installation, simplifying the installation process to a certain extent and improving efficiency. Sealed angular contact ball bearings reduce the possibility of lubricant leakage, significantly reduce maintenance costs, support long-term use in equipment, and reduce the frequency and cost of bearing replacement. Sealed bearings have excellent durability performance. The BNR/BER series ultra high speed sealed angular contact ball bearings prevent grease leakage through optimized design of the gap between the sealing ring and the cage, as well as the labyrinth structure of the sealing ring. The bearings of the 29 and 20 series have been specially designed to increase the amount of grease filling, suppress temperature rise, and achieve long grease life while preventing external foreign objects from entering. Note that the sealed bearing is filled with high-grade, low viscosity grease, which accounts for approximately 15% of its free space. Sealed bearings do not require lubrication under normal operating conditions. Bearings that have been filled with grease and bearings with sealing rings do not need to be cleaned during installation, but external rust proof oil should be wiped off with a clean cloth before installation.

Our company has professional sales and technical engineers who are responsible for providing users with technical consultation, technical services and product technical training on precision bearing data and installation and use. Perfect pre-sales, in-sales and after-sales services constitute a guarantee system for high-quality services, providing users with reliable quality bearing products and creating excellent user experience and rich benefits for every customer.
