Component Specifications

Definition
Ball screw wipers and seals are critical protective components installed at the ends of ball screw assemblies. They function as barriers that prevent external contaminants (dust, chips, moisture) from entering the precision ball-nut interface while simultaneously retaining internal lubrication. These components maintain the cleanliness of the ball recirculation system, reduce abrasive wear, and extend the operational lifespan of the entire linear motion system.
Working Principle
Wipers use flexible lips or blades to physically scrape contaminants from the screw shaft as it retracts into the nut. Seals create a tight interference fit against the shaft using elastomeric materials to form a barrier against fine particles and fluids. Some designs combine both wiping and sealing functions in a single integrated component.
Materials
Common materials include polyurethane (PU), nitrile rubber (NBR), fluoroelastomer (FKM/Viton), and polytetrafluoroethylene (PTFE). Material selection depends on operating temperature (-40°C to 120°C typical), chemical exposure, speed, and required sealing force.

  • Pressure Rating 0.1 to 0.3 MPa
  • Friction Coefficient 0.1 to 0.3
  • Operating Temperature -40°C to 120°C
  • Shaft Diameter Compatibility 6mm to 80mm
Standards
ISO 3408, DIN 69051

Frequently Asked Questions

What is the difference between wipers and seals in ball screw assemblies?

Wipers primarily remove larger contaminants from the screw shaft surface, while seals provide a tighter barrier against fine particles and fluids. Many modern components integrate both functions.

How often should ball screw wipers/seals be replaced?

Replacement intervals depend on operating environment and cycle count. In clean environments, inspect annually; in harsh conditions, inspect quarterly. Typical service life is 10^7 to 10^8 cycles.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
