6818 2rs Bearing Product Overview & Core Advantages
The 6818 2RS is a metric single row deep groove ball bearing designed for reliable performance in demanding applications. Its sealed construction provides robust protection against contaminants, making it an excellent choice for environments where maintenance access is limited. This bearing is engineered to primarily handle radial loads with high efficiency, featuring a compact cross-section that saves valuable space in machinery design. Manufactured to ABEC-1 precision tolerances, it delivers consistent operation and is pre-lubricated for immediate installation and long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6818 | Basic bearing designation indicating a single row deep groove ball bearing with a 90mm bore diameter, 115mm outside diameter, and 13mm width. |
| 2RS | Signifies double rubber contact seals on both sides, providing superior protection against contamination and moisture ingress while retaining lubrication. |
6818 2rs Bearing Structural Features & Performance Benefits
Robust Sealed Design: The double rubber seals (2RS) create an effective barrier against dust, dirt, and other contaminants, significantly extending bearing service life in harsh operating conditions. This sealed configuration also helps retain lubrication, reducing maintenance requirements.
Optimized Load Capacity: Engineered with chrome steel rings and balls, this bearing delivers excellent radial load capacity with dynamic and static ratings of 4118 lbf and 4388 lbf respectively. The deep groove raceway geometry ensures smooth operation under varying load conditions.
Precision Performance: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (C0) of 0.012mm to 0.036mm, this bearing provides consistent running accuracy and minimal vibration for reliable machine operation.
Durability & Compatibility: The stainless steel cage ensures dimensional stability and corrosion resistance, while the bearing's compliance with ROHS and REACH standards makes it suitable for various industrial applications with environmental considerations.
