Overview
The RBC Bearings B16LFSS is an industrial-duty spherical plain bearing designed for heavy radial load support with angular misalignment tolerance. This sealed variant features RBC’s signature fractured outer race design for simplified installation and removal, making it an ideal replacement or upgrade for existing bearing assemblies in demanding motion control and power transmission systems.
Key Features
- Sealed design with thermal plastic elastomer seals to exclude contaminants and retain grease
- Fractured outer ring enables tool-free, rapid assembly and disassembly
- 52100 bearing-quality steel construction, hardened to HRC 56 minimum for wear resistance
- Supports high oscillating radial loads and moderate thrust loads with 13° misalignment tolerance
- Phosphate-treated and dry-film lubricated surfaces for static and low-speed applications
- Oil holes and lubrication grooves in both inner and outer rings for field relubrication
