Tsubaki offers lube-free chain technology

A Tsubakimoto UK product story
Edited by the Engineeringtalk editorial team Oct 27, 2008

Lube-free, oil-impregnated sintered roller chains and engineered plastic/stainless steel combination chains from Tsubaki dispense with the need to use external lubricant.

Tsubaki's lube-free technology, in the majority of applications, are a size-for-size direct replacement for conventionally lubricated chains.

Food production and packaging environments in particular that have traditionally used expensive food grade lubricants can now operate without the need for chain lubrication, even in some arduous washdown environments.

A de-palletising machine at one of the UK's largest butter processing sites is using lube-free Tsubaki corrosion protected drive chain to overcome issues with both lubrication and corrosion.

The company imports over 26,000 tonnes of butter into the UK every year.

The butter arrives on pallets holding 50 blocks each, it is then thawed, salted and processed into retail packaging.

Due to the food grade nature of the plant, each machine is washed down using high-pressure salt water at 70C after each shift.

The Lambda WP chain from Tsubaki requires no external lubrication due to specially sintered oil impregnated rollers and is coated with a water protective finish.

It is able to work cleanly in a food processing environment and can withstand extremely arduous conditions without corroding.

There are a number of ways to achieve non-lube performance of chains.

These vary with the load capacity and life requirements.

Engineering plastic is the material used for the inner links on the Tsubaki PC chain.

PC chains are lube-free chains used in power transmission and conveying applications in the lighter side of the packaging industry, typically in food production or medicines.

They have no rollers; instead they rely upon the self-lubricating properties of the plastic from which their inner links are made.

The PC chain is 50 per cent lighter than all stainless steel chains, which gives easier handling and installation.

In addition, corrosion resistance is often greater than that of an all-metal alternatives.
