James Walker has released a two-part rotary sealing guide, focusing on Walkersele high-efficiency radial lip seals. Part One covers the selection of the correct seal design and material combination to suit each specific rotary application. The guide takes the user through operational parameters, performance, material compatibility, housing design and retention methods.

This helps in accurate seal specification and in allowing housing and retention issues to be addressed at the design stage. With the ideal seal/housing/retention combination as an integral part of the design, operational problems can be eliminated. The Walkersele Guide also contains a detailed section on seal installation techniques, including the James Walker on-site joining (OSJ) technique, plus operational considerations for worn shafts, highly abrasive or corrosive environments, shaft and housing surfaces, and lubrication. Range charts cover standard metric and inch sizes for split and endless seal variants.

This combines with Part Two of the guide - the Walkersele Mould List - which presents details of over 4,500 Walkerseles for which tooling is held, including a range of large- diameter tunnel-boring machine seals (TBMSs). 'Using this publication will speed up the whole ordering and delivery process for customers, whether they require a product from our standard mould list or are creating specifications for a custom seal. 'Tooling for non-standard sizes can be in-house designed and manufactured within days,' says James Walker product streams operations director, Geoff Teasdale. The two-part Walkersele Guide can be downloaded in PDF format, or a hard copy of Part One ordered directly from the company website.

R And W has released a handbook for the design and application of safety and overload couplings, as a part of a series of technical handbooks for the European manufacturing industry. Covering the basics of what torque limiters are, the varieties available, and why they are used, all the way though complex theories and advanced sizing formulas used to determine optimum coupling selection, this handbook includes information for design engineers at any level who need torque overload protection. This is the second of a two-part series, with the first book handling the design and application of precision couplings and line shafts.

Igus has released an online pinout configurator, Quickpin 2.0. It can be used to configure cables or connectors online, request the price (including copper surcharge), order directly and generate an ePlan electric P8 macro free of charge for every cable. The whole process takes only a few minutes. Accessories can be chosen from more than 850 Chainflex cables and 3,000 plug components. Another useful tool is the online product configurator for energy chains. Alongside 3D CAD data, users can download Excel spreadsheet part lists directly, and place orders through the shopping basket function simultaneously. The improved shopping basket, with intuitive user guidance, enables customers to get to the enquiry or order in five easy steps.
