Scrapers

Product catalog summary

Overview
The document provides technical specifications for the DANA WIPER TW41 and TW43 series scrapers, designed for hydraulic systems. It also covers the HRDA, HRDIC, and HRCM series wipers, used in industrial applications to maintain cleanliness and efficiency in mechanical systems.

Materials

Scrapers: Rings made from PTFE filled with bronze, carbon/graphite, or carbon fibers, and polyurethane. O-rings available in NBR, FKM, and EPDM.
Metallic Wipers: Include materials like aluminum, brass, AISI 304, steel, thermoplastic, FKM, EPDM, filled PTFE, and polyurethane.
HRCM Wipers: Made from NBR and FKM with metal cases.
HRDA Wipers: Made from NBR, FKM, and polyurethane.

Specifications

Scrapers: Speed up to 15 m/s, temperature range -50°C to +200°C, compatible with all hydraulic fluids.
Metallic Wipers: Speed up to 1 m/s, temperature range -50°C to +200°C, suitable for all fluids depending on materials.
HRCM and HRDA Wipers: Speed up to 1 m/s, temperature range -30°C to +100°C, suitable for HL, HLP oils, and air.

Operating Conditions

TW41 Series: Single acting scraper with low friction and high scraping efficiency.
TW43 Series: Double acting scraper with similar benefits.
Wipers: Designed for double-acting effects, providing high scraping efficiency and retaining residual oil films.

Dimensions
The document includes tables listing dimensions for various scraper models, indicating rod diameter, outer diameter, and length for each part number. Dimensions in bold conform to ISO 6195/B and NF E 48038 standards.

Ordering Information
Examples are provided for specifying orders based on series number, rod diameter, and material codes.

Advantages

Metallic Wipers: Effective scraping in the presence of solid deposits, high abrasion resistance, no scratching on rods, easy maintenance.
HRCM Wipers: Economical, easy installation, simple groove design.
HRDA Wipers: Double acting effect, low friction, easy installation, low cost.

Product Range
The document details various series such as HRDA, HRDIC, and HRCM, each with specific applications and dimensions. The HRDA series focuses on larger diameters, while the HRDIC series includes dimensions compliant with ISO 6195/C standards.

Additional Information
Intermediate sizes are available upon request, indicating customization options for specific industrial needs.
