Small Pitch Conveyor Chains : High Precision / Indexing / Conveyance (Bearing Bush Chain)
BACK
Chain with needle bearings and block type base for high speed/high accuracy positioning or precise indexing.
Product Types
Bearing Cage Chain
Uses a needle bearing cage (of engineering plastic) between the pin and bush; steel base chain, outer plates are blackened and inner plates are nickel-plated.
Bearing Bushing Chain Standard Series
Zero wear elongation chain that uses special needles allowing usage in conveyance systems considered impossible up to now.
High precision and stainless steel specifications available in addition to our standard specification.
RF-NBH High-precision Specification
Top Surfaces of attachments are ground smooth.
Link plates are nickel-plated except for top surfaces of attachments.
The space between bushes and rollers is smaller.
RF-NB-SS Stainless Steel
All parts except needles are stainless steel.
Bearings are sealed to allow use where dripping water is present.
Minimum chain wear elongation.
