GEBK Series Radial Spherical Plain Bearing Steel Brass 52100 Hard Chrome Plated 4 Piece ISO Standard

GEBK Series Radial Spherical Plain Bearing — 52100 Steel, Brass Liner, DIN ISO 12240-1

The GEBK series is a comprehensive range of radial spherical plain bearings conforming to DIN ISO 12240-1 dimension series K. Built with a robust 4-piece maintenance-required construction, each bearing combines a 52100 bearing steel inner ring with hard chromium plating, a brass insert liner, and a carbon steel outer ring for reliable performance in grease-lubricated applications.

Key Features

• 52100 Bearing Steel Inner Ring: Premium-grade 52100 (100Cr6) bearing steel, hardened, precision-ground, and treated with hard chromium plating on the spherical sliding surface for superior wear resistance
• Brass Insert Liner: High-quality brass liner provides an excellent sliding partner to the hard chrome plated inner ring, delivering smooth operation with proper grease lubrication
• Steel/Brass Sliding Contact: Optimized material pairing ensures reliable tribological performance and extended service life under maintained lubrication conditions
• 4-Piece Construction: Robust multi-piece design for secure assembly, consistent dimensional stability, and ease of installation
• DIN ISO 12240-1 Compliant: Manufactured to international dimension series K standards for guaranteed interchangeability with major bearing brands
• Carbon Steel Outer Ring: Formed carbon steel with protective oil coating, designed for press-fit housing installation
• Wide Temperature Range: Suitable for applications from -50°C to +150°C when paired with appropriate high-performance grease
• Maintenance Required: Designed for periodic grease relubrication to maximize bearing life in demanding applications
