6018 NR Bearing Product Overview & Core Advantages
The 6018 NR is a single row deep groove ball bearing designed for exceptional performance in demanding radial load applications. Its key advantage lies in its snap ring groove and fitted snap ring on the outer ring, which provides secure axial location within a housing, simplifying assembly and reducing overall design space. Manufactured from high-grade chrome steel with a stainless steel cage, it offers reliable operation, high durability, and is suitable for a wide operating temperature range. This bearing is an ideal choice for applications requiring a compact, easily mounted, and robust precision bearing solution.
6018 NR Bearing Model Code Explained, Specifications & Naming Convention
The model number 6018 NR can be broken down as follows:
- 60: Deep Groove Ball Bearing Series.
- 18: Bore diameter code, indicating a 90 mm bore.
- NR: Signifies that the bearing is equipped with a snap ring groove and a fitted snap ring on the outer ring. This feature allows for simplified axial positioning.
Additional Standard Specifications:
- Seal Type: Open - Designed for applications where external sealing is provided separately.
- Tolerance Class: P0 (Normal) - Standard grade for general applications.
- Radial Internal Clearance: CN (Normal) - Standard clearance for common operating conditions.
6018 NR Bearing Structural Features & Performance Benefits
The design of the 6018 NR incorporates several key features that deliver distinct performance benefits:
- Snap Ring Groove & Fitted Snap Ring: This critical feature eliminates the need for complex housing shoulders or end caps, enabling a more compact and cost-effective housing design. It ensures secure axial location, preventing creep under load and simplifying maintenance.
- High Load Capacity: The optimized single row deep groove raceway geometry enables the bearing to support high radial loads (13,601 lbf dynamic / 11,240 lbf static).
- Stainless Steel Cage: The use of a stainless steel cage provides high strength and corrosion resistance, contributing to the bearing's reliability and long service life, even in challenging environments.
- Precision Engineering: Manufactured to standard P0 tolerance and CN radial clearance, this bearing ensures consistent performance and smooth operation, making it a dependable precision bearing component.
