RLS 18 Bearing Product Overview & Core Advantages
The RLS 18 is a high-precision, single row deep groove ball bearing designed for demanding industrial applications. Engineered to P6 tolerance class, it delivers exceptional running accuracy and dimensional stability. Its primary function is to support substantial radial loads, as evidenced by its high dynamic and static load ratings. Manufactured from Chrome Steel for both rings and balls, and featuring a Stainless Steel cage, the RLS 18 offers excellent durability and reliable performance in a wide operating temperature range. Its open design allows for custom lubrication schemes to suit specific application needs, making it a versatile and robust choice for high-performance machinery.
RLS 18 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| RLS 18 | The base model number, indicating a specific bearing size and internal design in the inch series. |
| (No Suffix) | The absence of a suffix denotes an Open (unsealed) bearing, allowing for high-speed operation and custom lubrication. |
| (Implied) | Manufactured to a P6 tolerance class for superior dimensional precision and running accuracy. |
| (Implied) | Standard CN radial internal clearance is supplied. |
RLS 18 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The single row deep groove design, combined with P6 tolerance and tight dimensional tolerances on the bore diameter and outside diameter, ensures precise shaft positioning and high system rigidity.
- Superior Load Capacity: Engineered to handle high radial loads with a dynamic load rating of 11847 lbf and a static load rating of 8093 lbf, providing reliable support in strenuous conditions.
- Optimized for High Speeds: The Stainless Steel cage provides strength and stability, contributing to a high limiting speed of 8000 rpm. The open design minimizes friction and heat generation.
- Versatile Application Potential: The open seal type and none pre-applied lubrication offer flexibility. It can be lubricated with grease or oil best suited for the specific operating environment, including within its temperature range of -30°C to 120°C.
- Durable Construction: The use of Chrome Steel for critical components ensures high wear resistance and a long operational life.
