MGC Conveyor Chains Quality Power Transmission Products to meet your demands... The precision conveyor chain consists of a series of journal bearings held to each other by constraining link plates. Each bearing is made up of a case hardened pin and bush on which the roller revolves. CHAIN STANDARD/TYPE OF CHAINS MGC chains are made and comply mainly to BS Standard, ISO Standard. The range covers Solid Bearing Pin, Hollow Bearing Pin, and Deep Link either with rollers or in bush chain design. MATERIALS/TREATMENT Plate – SC45 steel or high tensile steel and heat treated when necessary to give higher breaking strength Pin – Hardened and tempered to achieve greater core strength ensuring the better performance. Bush – Solid bush, shouldered to avoid plate drift and extra wall thickness under roller to improve life span. Roller - Solid or sintered with boss design to avoid materials from entering between roller and inner plate. ASSEMBLY Strict control is taken at the clearance between inner and outer plates. This precision clearance is necessary as it can reduce the risk of wear on chain and prevent chain seizure in dusty/abrasive operation as there is adequate space for lubrication. Tolerance between pin, bush and side plates are observed and fitting to great accuracy. This increased the fatigue life of the chain. The concentricity of both the roller and bush are well in place due to the control in treatment and machining works and this maximize the life span of the roller and bush. Rigid check on pitch accuracy optimized lower wear due to friction and reducing in noise during operation QUALITY ASSURANCE With controls at every stages of manufacturing, MGC chains is consistent in reliability and it quality meets the highest standards. 1 (i) Total Chain pull = P (ii) Estimated Weight of Chain + Attachments + Slats = F 2 P = Chain pull in lbs/ft S = Speed in rpm ( usually a minimum factor of 8 ) Moderate / Clean environment Dirty / Abrasive condition 33000 When total chain pull is ascertained, divide it by the number of chain to find chain pull per chain. Selection Of Chain No. of Chain P x S Horse Power Formula Total Chain Pull * Weight Of Slat = Based on estimation, the weight of slat is usually twice the weight of chains + attachments.
