45# Steel Precision Spacer (Spacer Ring)

Product Overview
The 45# Steel Precision Spacer (Spacer Ring) is a critical internal component used to adjust the spacing between mechanical parts and precisely position bearings or gears. Through meticulous surface grinding, these spacers ensure micron-level axial accuracy, preventing component displacement during high-speed operation. They are widely utilized in gearboxes, machine tool spindles, and heavy-duty transmission systems.

Key Features

1. High Parallelism & Flatness

Utilizing double-disc precision grinding, we ensure that both end faces are highly parallel (typically within 0.005mm - 0.02mm), guaranteeing the assembly accuracy of bearing sets or gear trains.

2. Excellent Compressive Strength

The hardness of 45# steel after Quenching & Tempering (HB 220-250) ensures it won't undergo elastic deformation under massive axial clamping forces, maintaining long-term stable positioning.

3. Customizable Dimensions

We provide full customization for Outer Diameter (OD), Inner Diameter (ID), and Thickness to meet the specific spacing requirements of non-standard mechanical designs.

4. Cost-Effective & Reliable 1045 Steel

Compared to expensive alloy steel spacers, ASTM 1045 (45#) steel offers sufficient strength with a much higher cost-benefit ratio, and the stable material supply allows for efficient mass production.
