ELECTRO HYDRAULIC TAPPING UNIT BEG 55

Product catalog summary

Performance Specifications
The BEG 55 Electro Hydraulic Tapping Unit is designed for high performance with a maximum thrust of 6,000 N and a stroke length of up to 120 mm. It offers a minimum center-to-center spacing of 140 mm for single spindles and 17 mm for double-spindle heads. The unit ensures high precision with a depth accuracy of +/- 0.01 mm and operates at a sound level below 80 dB(A). The rapid advance rate can reach up to 6 m/min, while the controlled feed rate ranges from 0.04 to 0.65 m/min.

Design and Features
The BEG 55 series is compact yet powerful, featuring an integrated hydraulic system and a long stroke capability of 120 mm. It is designed for high precision and low noise operation. The electric motor drives the spindle, and the hydraulic system controls the feed, allowing for rapid advance and adjustable feed rates.

Guidelines for Unit Selection
The unit is suitable for tapping in various materials, with specific capacities for steel, aluminum, brass, and plastics. It is recommended not to exceed 2000 rpm when using a floating holding, especially for deep or blind holes and large threads.

Motor and Transmission Specifications
The motor specifications are valid for 380–420V(Y)/220–240V(Δ) at 50 Hz, with options for 440–480 V(Y) at 60 Hz, which increases rpm by approximately 20% and power by 15%. The torque at the spindle is calculated using the formula: M = (P[kW] x 9500) / rpm.

Dimensions and Accessories
The document provides detailed dimensions and necessary components for the unit, including tapping attachments, tap holders, controls, and multi-spindle heads. Additional resources such as 2D CAD drawings and 3D CAD models are available online.

Ordering Information
When ordering, specify the model, chuck size, control system, spindle rpm, motor power, motor orientation, and any required float compensation. Length compensation is available up to 25 mm for the GS12E tapping spindle and 40 mm for the GS24E.

ELECTRO HYDRAULIC TAPPING UNIT BEG 55 BEG 55 is a powerful yet compact electro-hydraulic series of units. The electric motor runs the spindle, while the feed is hydraulically powered and controlled. Hydraulic feed control makes it possible to use rapid advance and to adjust the feed rate in proportion to the pitch and the rpm. A tapping spindle gives the unit the necessary length compensation. The series is available in two different taper options as well as with multi-spindle heads. • COMPACT DESIGN YET POWERFUL • INTEGRATED HYDRALIC SYSTEM • LONG STROKE - 120 MM • HIGH PRECISION • LOW NOISE LEVEL TAPPING UNIT [M-Thread] CAPACITY IN PLASTICS "1 2 3 4 Performance specifications Depth accuracy +/-Rapid advance rate (max.)

These motors can also be used at 440480 V(Y) (±5%), 60 Hz. If so the rpm will increase by ~20% and the power by ~15% relative to the data for 50Hz. E2 also offers motors for other voltages and frequencies. Please state voltage and frequency when requesting a quote or ordering. • The torque at the spindle for a specific rpm is calculated as: M = (P[kw] x 9500) / rpm E2 does not recommend tapping with a floating holding at higher speeds than 2000 rpm. Maximum speed is lower when tapping a deep or blind hole and/or using a large thread.
