HepcoMotion PSD80 screw driven linear actuator This data sheet interacts with No.1 Ballscrew PSD80 The HepcoMotion PSD80 Ballscrew unit is a new addition to the popular PSD80 screw driven linear range. Combining Hepco Herculane® wheel technology with a ballscrew drive, the PSD80 ballscrew unit provides excellent all round performance in a compact and cost effective package. High precision ballscrews with pitches of 4, 5, 12.7 & 25.4 are available and carriage speeds from zero to 1m/s. PSD80 ballscrew units are capable of thrust loads of up to 4000N. The PSD80 beam profile is compatible with the Hepco MCS aluminium frame construction system, and can be assembled into multi-axis systems with Hepco PDU2 and PDU2M units. PSD80 Ballscrew Unit Internal Buffers • End of stroke protection at both ends. Carriage • High load capacity - up to 500N and 7.5Nm • Speed - up to 1m/s • Multiple carriages on a single unit available • Top plate easily removed & machined. Steel Ballscrew • Smooth, strong & precise. Available in leads of 4, 5, 12.7 & 25.4mm with right handed threads, and 5mm only with left handed threads. Stainless Steel Cover • Effectively seals the unit from debris. Steel Ballnut • High efficiency and low friction • Wear resistant and high reliability Hepco Herculane® Wheels • Ultra high performance wheels mounted in adjustable carriage body for zero play. Aluminium Beam • Rigid & lightweight • T-slots in bottom & side faces • Lengths to 3m + Limit Switch & Bracket • Mechanical & inductive versi

Data & Dimensions - Ballscrew Double Acting Units PSD80 Ballscrew Double Acting Unit Beam Length = 5770mm max = 2 x Stroke Length + 498 193 160 All other dimensions of double acting PSD80 units are the same as the closed units shown PSD80 double acting units have two (or more) carriages whose movements are symmetrical about the middle of the beam, this motion being achieved by using linked left and right hand threaded screws. The units may be ordered with 5mm screw leads only. They share the same major parts, and have the same benefits as other PSD80 units, and are available in closed...

Calculations & Performance Carriage Service Interval Calculation After very long service, slight play in the carriage may develop due to wheel wear. This can be corrected by re-adjusting the carriage, which will return the unit to its original condition. Adjustment is quick and simple and may be repeated several times. The table shows the maximum carriage loading, and the calculation below determines the service interval. Hepco will provide more data and calculations for your application, on request. Ms Carriage Load Capacity L1 To determine service interval, first calculate the load factor...

Calculations & Performance Rotary - Linear Speed Equivalence Motor Speed rpm Thrust Load Performance The amount of thrust that a PSD80 ballscrew unit can produce depends upon the screw lead type, the speed of the system, and the life required (see 5). Please contact Hepco for advice on suitability for your duty. The table below provides the thrust capacities of each nut type and typical thrust capacities of the PSD80 ballscrew unit. In many applications, the capacity of the nut itself does not limit the maximum thrust load of the PSD80 ballscrew unit. Please also refer to the critical speed...

How to Order This ordering information is given to assist communication, but we recommend that you discuss the application with Hepco first so that we can help to specify the best unit for your needs. Main Unit Product range = PSD80 L1246 = beam length in mm (max 2850 for standard, 5770 for double acting and 6000 for slave units). T = beam with T-slots (this is the only option at present). Unit configuration: C = Closed. Drive type: D = Driven; DA = Double acting; S = Slave; SW = Slave without spacer. B5 = Screw lead in mm. Choose from B4, B5, B12.7, B25.4 and LB5 (Left hand thread). CP1 =...
