Overview

The document details the specifications, variants, and accessories of the VRTP series of spoked handwheels made from technopolymer materials. These handwheels are designed for mechanical operating elements and comply with RoHS standards.

Material and Construction

• Material: High-resilience polypropylene (PP) technopolymer, black color, matte finish.
• Boss Cap: Anodised aluminium self-adhesive front plate; for VRTP.375, a polyester-based technopolymer (PBT) cap in RAL 7035 grey, glossy finish, press-fit assembly.
• Boss: Black-oxide steel with H7 reamed hole.

Standard Versions

• VRTP.: Basic handwheel without handle.
• VRTP+I: Handwheel with revolving handle I.621+x in technopolymer.
• VRTP+IEL: Handwheel with revolving handle IEL+x SOFT, coated with thermoplastic elastomer (TPE) for a soft touch.
• VRTP+IR: Handwheel with fold-away handle IR.620 in technopolymer.
• K Index: Versions with hole and keyway compliant with DIN 6885/1, tolerance P9.

Accessories on Request

• GN 184: Axial retaining washer in black-oxide steel.
• ECB.T: Glass-fibre reinforced polyamide (PA) technopolymer boss caps available in various Elecolors (RAL colors) with matte finish and press-fit assembly, compatible with VRTP.125, VRTP.160, and VRTP.200.

Technical Specifications and Dimensions

The document provides detailed tables listing the dimensions and mechanical parameters for each VRTP model and variant, including:

• Diameter (D), hole diameter (dH7), length (L), width (B), and other dimensional parameters (d1, d2, d3, d4, h, H, m, R).
• Maximum torque (C) in Newton-meters (Nm) and impact strength (L) in Joules (J).
• Thread sizes for handles (e.g., M6, M8, M10).

Models range from VRTP.80 to VRTP.375 with various hole sizes and handle options. The tables specify exact measurements for each variant, enabling precise selection based on application requirements.

Ordering Information

• To order versions with hole and keyway, add the suffix "-K" to the product code and description.
• Color codes for ECB.T boss caps must be specified using the provided RAL color indices.

Key Parameters and Recommendations

• Operating temperature range: 0°C to +80°C.
• Material compliance with RoHS directives.
• Use of soft-touch handles (IEL) recommended for ergonomic applications.
• Selection of handle type depends on user preference and application needs (fixed, revolving, fold-away).

Summary

The VRTP spoked handwheels offer a versatile range of sizes and handle configurations made from durable technopolymer materials suitable for various mechanical operating applications. Detailed dimensional and mechanical data support precise specification and ordering. Optional accessories and color variations enhance customization possibilities.
