Why Choose SN Series

Key Features & Improvements

Engineering advancements that make the SN Series the smarter, longer-lasting choice.

  • Split-Housing Design: The horizontal split allows for easy assembly and disassembly, reducing downtime during maintenance or bearing inspections.
  • Axial Flexibility: The bearing seat is precision-machined to be wider than the bearing. This provides "axial freedom," allowing the shaft to expand or move naturally.
  • Fixed Positioning: For applications requiring a fixed (locating) bearing, the SN series can be easily converted by inserting one or two locating rings.
  • Optimized Lubrication: Designed specifically for grease lubrication to ensure smooth operation. We can provide high-quality felt strips and grease nipples upon request.
