Overview

This document provides detailed technical specifications for the PreCom IGWA series shaft support blocks, focusing on dimensions, weights, and tolerances for various standard sizes.

1. Product Description

The IGWA series consists of standard shaft support blocks designed for precision applications. These components are identified by type numbers such as IGWA-08, IGWA-12, IGWA-16, IGWA-20, IGWA-25, IGWA-30, IGWA-40, IGWA-50, and IGWA-60.

2. Dimensional Specifications

Dimensions are provided in millimeters (mm) and include key parameters:

• Ød: Shaft diameter
• A1: Specific dimension related to the block
• SW: Width across flats
• Ød1: Secondary diameter
• V, H, h, B, A, E: Various height, width, and length dimensions relevant to the block geometry

Each IGWA type has specific values for these parameters, for example:

• IGWA-12: Ød = 12 mm, Weight = 0.02 kg
• IGWA-16: Ød = 16 mm, Weight = 0.03 kg
• IGWA-20: Ød = 20 mm, Weight = 0.07 kg
• IGWA-25: Ød = 25 mm, Weight = 0.14 kg
• IGWA-30: Ød = 30 mm, Weight = 0.20 kg
• IGWA-40: Ød = 40 mm, Weight = 0.48 kg
• IGWA-50: Ød = 50 mm, Weight = 1.90 kg
• IGWA-60: Ød = 60 mm, Weight = 3.60 kg

3. Weight Information

The weights increase with the size of the shaft support block, ranging from 0.02 kg for the smallest (IGWA-12) to 3.60 kg for the largest (IGWA-60).

4. Tolerances and Precision

Dimensional tolerances are specified, for example:

• Diameter tolerance ±0.02 mm for certain dimensions
• Diameter tolerance ±0.15 mm for others

This indicates high precision manufacturing suitable for industrial applications requiring tight fits.

5. Manufacturer Information

PreCom Precision Components GmbH is the manufacturer, located in Blieskastel-Niederwürzbach, Germany. Contact details include telephone, fax, email, and website for further inquiries.
