3/16" Chrome Steel G25 Precision Bearing Ball

Introduction

PGN 3/16" Chrome Steel Bearing Balls are designed for compact mechanical systems that require consistent spherical geometry, a smooth surface, and durable steel construction. Measuring 3/16 inch, or 4.7625 mm, this size provides a practical solution for small bearing assemblies, positioning mechanisms, and replacement applications where component dimensions must be carefully matched.

Manufactured from chrome steel and classified as G25, this bearing ball is intended for compatible applications involving rolling contact, controlled movement, and repeated mechanical interaction. Chrome steel offers good wear resistance when properly specified, while the finished surface supports smooth contact with races, tracks, seats, and surrounding components.

With a listed unit weight of approximately 0.01566 ounces, or 0.44398 grams, the 3/16 inch format is well suited to compact mechanisms where component mass, available space, and responsive movement are relevant design considerations. Final suitability depends on the complete assembly, operating environment, lubrication, and engineering requirements.

Compact Diameter for Responsive Mechanisms

The 3/16 inch diameter provides a compact spherical component for mechanisms where available space is limited and controlled movement is required. Its smaller mass may support responsive operation in properly designed indexing, positioning, and rolling systems.

Correct sizing remains essential because even small dimensional differences can affect clearance, fit, contact pattern, and movement within the assembly.

Chrome Steel for Repeated Mechanical Interaction

Chrome steel is commonly used for bearing-related components because it offers durability and good wear resistance under suitable operating conditions. This makes it appropriate for compatible mechanisms involving repeated rolling, contact, or positional movement.

Chrome steel is not stainless steel and may corrode when exposed to moisture. Proper lubrication, handling, and dry storage may help protect the surface.

G25 Precision for Consistent Geometry

The G25 classification identifies the precision level of the bearing ball and supports applications where consistent diameter and spherical form are important.

This dimensional consistency may contribute to more predictable contact and movement when the ball is properly matched with compatible races, seats, guides, or other mechanical interfaces. G25 alone does not determine the load, speed, or service capability of the complete system.

Smooth Surface for Rolling and Positioning Contact

The finished spherical surface is intended to support smooth interaction with surrounding components. Surface consistency is particularly relevant in mechanisms involving rolling motion, repeated positioning, or controlled contact.

Final performance depends on the condition and alignment of the complete assembly, as well as lubrication, contamination control, operating speed, and applied loads.

Lightweight Component for Detailed Assemblies

The listed unit weight is approximately 0.01566 ounces, or 0.44398 grams. This relatively low individual mass makes the 3/16 inch ball suitable for compact systems where component weight may influence movement, response, or mechanical balance.

The ball may also be used in prototyping, maintenance, and replacement work when its diameter, material, and precision classification match the application requirements.
