Table of Contents

1. Product Overview & Specifications

The 1217/1217K series features stainless steel (AISI 420) construction with GCr15 bearing-grade steel balls, enabling corrosion resistance and high-grade steel balls. Key specifications.

Parameter 1217 1217K
Bore Diameter (mm) 85 85
Outer Diameter (mm) 150 150
Dynamic Load Capacity (kN) 53.2 48.7
Seal Type Open Double Shielded

Competitor Comparison. 15% higher load capacity than standard 1200-series bearings due to GCr15 hardening process.

2. Key Applications & Industries

Primary industrial uses include.

  • Food Processing: FDA-compliant lubrication withstands washdowns
  • Marine Shaft Systems: Saltwater corrosion resistance (IP66 rating)
  • Mining Conveyors: Self-aligning capability compensates for ±3° shaft misalignment

3. Installation & Maintenance Guide

Mounting Procedure.

  1. Clean shaft/housing (Ra ≤ 1.6μm surface roughness)
  2. Heat bearing to 80°C max via induction heater
  3. Axial press-fit with <3kN force

Lubrication. Use ISO VG 32 synthetic grease (relubrication interval: 2,000 hrs @ 1,800 RPM).

4. Real-World Use Cases

Case 1: Paper Mill Roller System

  • Problem: Frequent failures in 95°C steam environment
  • Solution: 1217K with high-temp seals
  • Result: 3x lifespan increase (from 6 to 18 months)
