Ball Retainer / Recirculation System (Ball Screw only) Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A precision mechanical component in ball screws that houses and guides the recirculating balls between the screw shaft and nut. It maintains proper ball spacing, prevents jamming, and ensures continuous, low-friction linear motion by facilitating the return of balls through a recirculation path after completing one revolution.

Working Principle

The system captures balls as they exit the load-bearing zone and redirects them through a return tube or internal channel back to the starting point, creating a continuous recirculation loop. This allows unlimited travel length while maintaining consistent ball contact and load distribution.

Materials

Typically made from hardened steel (AISI 52100/SUJ2), stainless steel (AISI 440C), or engineering plastics (POM, PA) for corrosion resistance and durability. Surface hardness: 58-62 HRC for metal components.

Technical Parameters

Lubrication Grease or oil
Ball Diameter 1mm to 10mm
Load Capacity Dynamic: 5-500 kN
Recirculation Type External tube/Internal deflector
Operating Temperature -30°C to 120°C

Standards

ISO 3408, DIN 69051
