NB110AR0 Bearing Product Overview & Core Advantages
The NB110AR0 is a single row angular contact ball bearing engineered for precision applications requiring high reliability. Featuring an Endura-kote chromium plating surface treatment, this bearing delivers enhanced corrosion resistance and extended service life. Its 30° contact angle design provides superior performance in handling combined radial and axial loads simultaneously. Manufactured to ABEC-1 precision standards with inch dimensions (11" bore × 11.625" OD), this bearing offers exceptional dimensional stability and is pre-lubricated for immediate installation and operation across a wide temperature range from -30°C to 110°C.

| Code Segment | Technical Meaning |
| NB110 | Basic bearing designation with inch sizing |
| A | Angular contact design with 30° contact angle |
| R0 | Open construction (no seals/shields) |
NB110AR0 Bearing Structural Features & Performance Benefits
Premium Material Construction: Manufactured from chrome steel for both rings and balls, with a brass cage that ensures optimal ball guidance and high-speed capability. The Endura-kote chromium plating provides superior surface hardness and corrosion resistance.
High Load Capacity: Engineered to handle significant combined loads with a radial dynamic load rating of 1540 lbf and axial static load capacity of 4000 lbf. The 30° contact angle optimizes axial load transmission while maintaining radial load capability.
Precision Engineering: Built to ABEC-1 tolerance class with tight dimensional control (bore/OD tolerance: -0.0014" to 0"). Features minimal radial internal clearance (0.0000" – 0.0005") for precise positioning applications.
Thin-Section Design: With a compact 0.3125" width, this bearing offers space-saving advantages while maintaining structural integrity and load-bearing capacity.
