Product Description

2206 2RS Bearing Overview

The 2206 2RS bearing is engineered for reliability in demanding industrial environments. With an inner diameter of 30mm and double nitrile rubber seals, it offers optimal protection against contaminants while handling radial loads up to 12.3 kN. Ideal for mining equipment, medical devices, and heavy machinery, this self aligning ball bearing combines precision grinding (P0/P6 grades) with high-purity GCr15 steel for unmatched durability in demanding bearing applications.

Technical Specifications

Parameter Specification

Key Advantages

  • Double Seals (2RS): IP6X-rated double rubber seals prevent dust, water, and debris ingress into the bearing raceways.
  • Self-Aligning & High Load: Compensates for shaft misalignment while maintaining reliable performance under dynamic loads.
  • Customizable Design: Flexible options for fluorocarbon seals, ceramic hybrid balls, and solid lubricants for high-vibration equipment.

Where It's Used

  • Metallurgy Machinery: Resists thermal deformation in rolling mill roller bearing and ball bearing setups.
  • Medical Imaging Devices: Low-noise operation ensures smooth rotation in MRI and CT scanner bearings.
  • Port Logistics Equipment: Triple-lip seal variants provide high corrosion resistance in coastal crane bearings.

Quality Assurance & Delivery

Every 2206 2RS bearing undergoes spectral steel purity checks, laser-guided grinding verification (≤0.005mm), and 72-hour load simulations. Standard self aligning bearings ship in 48 hours with 15–20 day turnaround for custom orders.
