Supply Services Limited stocks the most comprehensive range of standard conveyor chains and industry specific conveyor chains in New Zealand. A full range of attachments, sprockets and accessories are available. These can be customised to meet your requirements.
These chains come in either cranked linked style (H Class) or straight side bar style (C Class). Both are normally cast in malleable iron, alloy steel or manganese steel. The C Class chains have carbon steel outer side bars which allow welding of attachments. Some common examples are H78, H82, C55, C188, C131, C102B and the rooftop series H78A, H78B, H130, H138, C55A, C55B, C55D.
Drop Forged Chains also known as En-Masse chains are versatile and simple chains with high strength and high wear resistance. They are capable of conveying a multitude of products on inclines up to vertical and at temperatures of up to 1000 °C (depending on the chain alloy selected). The conveyor design can be totally enclosed and very compact. Available pitches are 102mm, 142mm and 260mm.
These open barrel chains were originally developed for the agricultural industry. Generally, they are used in applications such as spreaders, feeder systems and spray boxes where sticky substances would otherwise seize a closed barrel type chain. Common chains are 667X, 667K, and 88K.
Various chains are used in this industry where they may either be steel or plastic. The plastic chains are becoming more common due to their resistance to corrosion, light weight and ease of installation. For example, PC720S (6.000” pitch) or PC78 (2.609” pitch) chains. Their metal counterparts being WR720S and WR78.
Long Link chains in imperial & metric configurations available in a range of pitch sizes. Round, oval & square link to suit different applications. Available in alloy steels, manganese, with through or case hardened options. High hardness, reduced elongation, resistant to shock loading.
Rivetless chain is drop forged from carbon steel, normalised, heat treated and quenched. This very simple chain design allows for tool free assembly or disassembly at any pitch in the chain. The standard chain allows for general applications, whereas the X-Series is specifically designed for overhead trolley conveyors.
European Metric chains are made according to 3 different styles DIN8167, DIN 8165 and SMS 1698. They are multi-purpose straight side bar conveyor chains useful for a multitude of applications. Pitches vary from 40mm to 500mm and ultimate tensile strengths from 40kN to 900kN.
Double Flex chains are Bi-Planer in nature and are designed to flex in two directions. They usually run around a horizontal radius and then return under the conveyor. Typical applications would be bottling conveyors, log turning and taking lumber around a bend. Common chains are malleable CC600 and DF3500.
BS Roller Conveyor chains generally to BS4116.Pt4.1992 are multi-purpose straight side bar conveyor chains useful for a multitude of applications. Pitches vary from 50.8mm (2”) to 381mm (15”) and ultimate tensile strengths from 26.7kN (6,000lb) to 750kN (170,000lb). Pins can be solid or hollow and the rollers can be either plain or flanged style. Many types of attachments can be fitted either as integral links or welded on. Connecting links are available as riveted, screwed, circlip and cotter pin.
