RLS 8 Bearing Product Overview & Core Advantages
The RLS 8 is a single row deep groove ball bearing manufactured to inch dimensions, designed for high-precision radial load applications. This bearing features a P6 tolerance class for exceptional dimensional accuracy and running precision, making it ideal for applications demanding high rotational accuracy and reliability. Its open design allows for versatile lubrication options and facilitates high-speed operation. Constructed entirely from high-grade chrome steel for the rings and balls, with a durable stainless steel cage, it offers robust performance and long service life.
RLS 8 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| RLS 8 | Basic model designation for a specific inch series single row deep groove ball bearing. | Defines the core bearing geometry and size series. |
| Open (Seal Type) | No integral seals or shields. | Enables high-speed operation and allows for custom lubrication schemes. |
| P6 (Tolerance) | Dimensional and running accuracy superior to standard (ABEC 1) classes. | Ensures precise shaft positioning, reduced vibration, and smooth operation. |
| CN (Clearance) | Standard radial internal clearance for normal operating conditions. | Provides optimal fit and performance under standard loads and temperatures. |
RLS 8 Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Manufactured to a P6 tolerance class with tight bore and OD tolerances, this bearing ensures minimal runout and high system rigidity for precise shaft rotation.
Radial Load Capacity: As a deep groove ball bearing, it is primarily designed to support significant radial loads (Dynamic: 4002 lbf, Static: 2169 lbf), making it a workhorse for many industrial applications.
High-Speed Capability: The combination of an open design, a precision-ground chrome steel raceway, and a lightweight stainless steel cage allows for a high limiting speed of 17,000 rpm.
Durability & Compliance: The use of chrome steel for rolling elements and rings ensures high hardness and wear resistance. The bearing is compliant with ROHS and REACH environmental standards.
