Conveyor Chain - Tsubaki

Bearing BushChainBearing Bush Chain is used in automatic assembling, packaging, filling, and parts installation for a variety of industries, includingelectric, electronic, semiconductor, automobile, and food as well as in other precision machinery. It includes the following features:High accuracy and no elongation. Interchangeability with other double pitch/ large pitch chains. Long wear life without lubrication.Usually chains are designed with gaps between the pins and bushings for proper operation. With Bearing Bush Chain, needle bearingsare installed between the pins and bushings. These add rolling elements between these components and eliminate the sliding friction.Immediately after installation, the chain stretches a little (less than 0.03%) to fit the contacting surface of chain parts. After that, itdoesn't stretch. Major dimensions of the Bearing Bush Chain and attachments are the same as our ANSI standard double pitchconveyor chains. Tsubaki Bearing Bush Chain works perfectly with standard over-sized roller sprockets. Changeover from standardroller chains to Tsubaki Bearing Bush Chains can be accomplished with minimal redesign of equipment.A-2 AttachmentSectionBK-2 AttachmentTL1L2φDφRWhHPPAll dimensions in inches unless otherwise stated.RollerDia.RWidthBetweenInner LinkPlatesWLink Plate PinLengthL 1 + L 2LengthL 1LengthL 2MaximumAllowableLoad(lbs.)MaximumAllowableRoller Load(lbs./roller)Approx.Weight(lbs./ft.)ChainNumberPitchPThicknessTHeightHHeighthDia.DOversize Roller TypeCN2042 1.000 0.625 0.313 0.059 0.689 0.473 0.156 0.717 0.325 0.392 176 33 0.66CN2052 1.250 0.750 0.375 0.079 0.827 0.591 0.200 0.878 0.406 0.472 287 44 1.16CN2062H 1.500 0.875 0.500 0.126 1.024 0.677 0.235 1.224 0.573 0.652 396 66 1.72CN2082H 2.000 1.125 0.625 0.156 1.378 0.906 0.313 1.543 0.720 0.823 660 121 2.60All dimensions in inches unless otherwise stated.A-2 and K-2 AttachmentsAdditional Wt. per Attach.
