1 TSUBAKI LOW NOISE DRIVE CHAIN NEW

2 Low Noise Drive Chain SN Roller Chain Tsubakimoto introduces its original spring roller for use in roller chain. When Tsubaki s SN Roller Chain engages with the sprocket, the new spring roller absorbs the force of the impact. The lower impact force results in lower noise levels. Compared with Tsubaki s standard RS Roller Chain (pre-lubricated), noise levels of SN Roller Chain are 6~8 db lower. Standard RS Roller Chain Roller Low Noise Drive Chain Spring Roller (Moldability) Noise Noise abatement What the change to Low Noise offers RS is a registered trademark of the Tsubakimoto Chain Co. Reduction of noise generated by machines and equipment in the workplace helps improve the overall work environment. Belts were considered as a countermeasure to noise, however, there are many limitations in terms of application, strength and overall cost. Taking these factors into consideration Low Noise Chain is the prefect countermeasure. Can be used in applications where the strength of a roller chain is required without the accompanying noise.
