INDUSTRY COMPONENT

Seals / Wipers

Seals and wipers for ball screw nut housings that prevent contamination and retain lubrication in drive mechanisms.

Component Specifications

Definition
Specialized sealing components installed in ball screw nut housings and other drive mechanism enclosures to create barriers against external contaminants (dust, chips, moisture) while retaining internal lubricants. These components typically include lip seals, wiper seals, and combination seals designed for linear motion applications with precise clearance requirements.
Working Principle
Seals function through elastic deformation and contact pressure against moving surfaces to create physical barriers. Wiper seals use scraping or wiping action to remove contaminants from shafts or screws before they enter the housing. Combination seals integrate both sealing and wiping functions in a single component through multi-lip designs that maintain consistent contact despite wear.
Materials
Nitrile rubber (NBR), polyurethane (PU), fluorocarbon (FKM/Viton), polytetrafluoroethylene (PTFE), fabric-reinforced elastomers. Material selection based on temperature range (-40°C to 200°C), chemical resistance, and wear characteristics.
Technical Parameters
  • Hardness 70-90 Shore A
  • Clearance 0.1-0.3 mm
  • Shaft Speed Up to 2 m/s
  • Pressure Rating 0-0.5 MPa
  • Operating Temperature -40°C to 150°C

Frequently Asked Questions

What is the difference between seals and wipers in drive mechanisms?

Seals primarily prevent lubricant leakage and contamination ingress through static sealing, while wipers actively remove contaminants from moving surfaces before they enter the housing. Many modern components combine both functions.

How often should drive mechanism seals be replaced?

Replacement intervals depend on operating conditions: typically 6-24 months in normal industrial environments, or based on visual inspection for wear, hardening, or damage during routine maintenance.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
