RW2-6 Bearing Product Overview & Core Advantages
The RW2-6 is a high-precision single row ball bearing designed for demanding applications requiring reliable performance in inch-sized machinery. Engineered with chrome steel rings and balls along with a stainless steel cage, it delivers excellent durability and corrosion resistance. Its extended inner ring facilitates easier mounting and axial location. This bearing is optimized for radial load applications and operates effectively across a wide temperature range from -86 to 230 °F, making it a versatile component for various precision assemblies.
RW2-6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| RW2-6 | Standard inch series designation for a single row radial ball bearing with specific bore and outside diameters. |
| Open (Seal Type) | The bearing is unsealed, allowing for custom lubrication schemes but requiring a clean operating environment. |
| Extended Inner Ring | The inner ring protrudes beyond the bearing width, simplifying axial positioning and locking. |
RW2-6 Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring consistent running accuracy and smooth operation.
Optimized Load Capacity: Features 7 high-grade chrome steel balls, providing a dynamic load rating of 122 lbf and a static load rating of 41 lbf for reliable performance under radial stresses.
High-Speed Capability: The lightweight stainless steel cage and precision geometry enable a limiting speed of 53,000 rpm, suitable for high-velocity applications.
Material Superiority: The use of chrome steel for rings and balls ensures high hardness and wear resistance, contributing to a long service life.
