TSUBAKI Indexing Conveyor Chains
Bearing Cage Chain

Uses a needle bearing cage between pins and bushes (cage is engineering plastic). Will not elongate further after slight initial elongation (0.03%) during first use.

The base chain is steel. Cheaper than Bearing Bush Chain.

Features

• Will not elongate further after slight initial elongation (0.03%) during first use.
• Cheaper than Bearing Bush Chain (Standard Series) for better cost performance.
• Operating temperature range: -10ºC to 60ºC
• Can use RF Double Pitch Sprockets for R rollers.

Structure

* The seal prevents grease from escaping. The space between pins and bushes has already been greased.
