KSS Lead Screws

A superb range of gothic arch thread form lead screws that ensure smooth linear movement. The lead screws are manufactured from 304 or 303 Stainless Steel delivering high postional accuracy and excellent corrosion resistance. Available in diameters of 4mm, 6mm, 8mm, & 12mm with leads of 1 to 30mm makes the series ideal for a multitude of precision linear applications. Complimented by a range of matched precision plastic nuts, all the screws can be delivered with machined end journals that are ready to fit directly into an application.

Type

MRH-A,B series

MRH-A,B series : KSS products

Using a non reactive Polyamide type resin for the nut material gives an excellent coefficient of friction. The material is impregnated with a lubricating agent that allows the nut and screw to be used without lubrication if required. However, lubrication is advised to increase operational and longevity. Other nut materials are available on request.

MRH-BP2 series

MRH-BP2 series : KSS products

Using a non reactive Polyamide type resin for the nut material gives an excellent coefficient of friction. Backlash free nut designs can be supplied using a double nut design with a captivated wound spring between them providing a preload. Other nut materials are available on request. .

R-MSS (Y) series

R-MSS (Y) series : NTN Corp. products

Using Bearee AS5000 plastic material for the nut enables a wide range of environmental application challenges to be overcome. Please note that high lead types (3 times as diameter.) are also available in this series.

Caution

1) Lubrication

  • Lubrication of the nut and screw mechanism is recommended where ever possible. We can offer advice on correct lubrication type depending on operating condition.

2) Additional end-journal machining

  • All lead screws can be supplied with machined end journals to print design. This is preferred method of supplying the resin screws series to ensure product quality, accuracy and concentricity of journals. By supplying a ready to fit product also eliminates the customers potential scrap rates.

3) Handling.

  • Do not subject parts to sudden impact.
  • Do not disassemble backlash free type nut.
  • When storing the products, please store in the original wrapping. Do not open the wrapping or tear the inner wrapping until ready to use.
  • This product has been designed for normal use in temperatures under 80°C. In case of exceeding 80°C, please ask ABSSAC.
  • Resin Lead Screws are mechanical components that generate thrust toward the centre of axis. They are not designed to accept radial load. Unsupported radial loads will result in premature wear and possible failure. 
  • Please ensure that the mounting of the nut bracket and support bearing, are perpendicular to the nut mounting face.

 

Linear guides and rails

KSS Lead Screws

Linear guideways provide excellent load bearing linear motion by re-circulating rolling elements between a profiled rail and a bearing block. By primarily using a four ball path design, within the slide, delivers excellent rigidity and parallelism during operation. The guides can be used in both vertical and horizontal planes.

GoABSSAC concentrates on the flanged mount and square mount versions of linear guides as these are considered ideal for use with lead screws...

Support Bearings

KSS Lead Screws

ABSSAC supplies both radial and thrust bearings, complete with housings, to compliment their expanding lead screw and ball screw ranges. All bearings include the bearing set, bearing housing, snap ring, lock nut, spacer ring and retaining cover. Available to suit all shaft sizes, the range delivers robust radial and thrust protection in any rotary or linear application. Let us help you with your selection.

GoThe latest range of  low-cost  precision quality thrust and radial bearing units from Abssac are ideally suited for lead screw and ball screw applications.

Custom Solutions & Reverse Engineering

KSS Lead Screws

ABSSAC welcomes reverse engineering applications. Over the years, many customers have sent damaged leadscrews and nuts for us to measure and replicate, often as a result that dimensional drawings do not exist. Please contact one of our knowledgable sales engineers for further details.
