Bearing Set - Inner Diameter 30.2, Outer Diameter 44 - GCr15

Bearing Set designed for dependable performance in precision machinery, this unit features an inner diameter of 30.2 mm and an outer diameter of 44 mm, crafted from high-grade GCr15 bearing steel. Built to handle demanding conditions, it delivers steady, long-lasting rotation in industrial, automotive, and robotics applications.

Why GCr15 matters

GCr15 is a high carbon chromium bearing steel renowned for hardness, wear resistance, and fatigue strength. In this bearing set, heat-treated GCr15 provides a robust race and raceway surface that withstands repetitive loads, minimizes wear, and promotes consistent performance over time. The result is reliable operation in environments where durability and precision matter most.

Key features that drive real-world value

• 
  Exact bore and OD sizing: 30.2 mm bore paired with a 44 mm outer diameter—designed to fit standard shafts and housings with tight, predictable clearance.
• 
  Hard-wearing construction: Heat-treated GCr15 steel offers superior hardness and wear resistance for extended service life in high-cycle applications.
• 
  Consistent performance: Precision-ground surfaces and controlled geometry support smooth rotation, reducing vibration and improving overall machine reliability.
• 
  Versatile compatibility: Ideal for radial bearing needs in CNC machines, automation gear, robotic joints, motor housings, and other machinery requiring precise 30.2/44 configurations.

Ideal use cases

• Replacement bearings in robotic actuators and CNC tooling where shaft diameters are specified around 30.2 mm.
• Automotive assemblies and agricultural equipment that demand durable, long-lasting bearing performance under repetitive loads.
• Industrial equipment housings and frames requiring a reliable, ready-to-install bearing of this exact size.
• Custom machinery projects where consistent bore/OD tolerances help ensure smooth, quiet operation and easy maintenance.

How this bearing set supports your project

Choosing a bearing set with a precise 30.2 mm bore and 44 mm outer diameter made from GCr15 delivers:

• Improved shaft alignment and reduced runout, contributing to higher machining accuracy and longer tool life.
• Lower maintenance costs thanks to enhanced wear resistance and fatigue strength under heavy or repetitive loads.
• Greater uptime with predictable performance, minimizing unexpected downtime and replacement frequency.

Practical care and installation tips

• Verify that shaft and housing dimensions match the 30.2 mm bore and 44 mm OD for a proper fit.
• Use appropriate lubrication and follow your equipment manufacturer’s lubrication schedule to maximize life and performance.
• Keep bearing surfaces clean during installation to prevent contamination that can compromise performance.
• Store in a dry environment to preserve the surface integrity of the GCr15 steel until installation.

Engineered for reliability, this Bearing Set—built from durable GCr15 steel with precise 30.2 mm bore and 44 mm outer diameter—offers a practical, long-term solution for demanding machines and assemblies. Whether upgrading existing equipment or building new systems, it provides the solid foundation your shaft and housing require for smooth, efficient operation.
