SKF’s transmission and conveyor chains are engineered to thrive in dust, endure shock loads and power through long hours
Backed by rigorous testing, smart lubrication and global support, they keep your headers, balers and pickers running – season after season.
Performance starts at the factory.
“It comes down to what goes in and how consistently it’s made,” says Simon Protheroe, who leads power transmission across India, Southeast Asia, Australia and New Zealand.
“Heat treatment runs in large, continuous batches; steels have known chemistry so treatment can be tuned; assembly tolerances are tight.
“Deliver every time with that consistency, and you’ll get the wear resistance you need.”
Rikus van Zyl, SKF’s global business line manager for power transmission, adds that every batch is tested and certified.
“Tooling is replaced on a fixed count, not when a gauge finally says it’s worn,” he says.
“The only way is to be predictably good. Sometimes-good, sometimes-bad confuses the market.”
The right chain for the job
Harvesters commonly use American Standard chain, and SKF covers the range.
“Heavy Duty options including H, SH, SHH, SPH – exist for a reason,” van Zyl says.
“A big round baler is a heavy-duty application; a standard chain won’t last there. The spec must step up.”
Beyond transmission sizes of 0.5 inches to 1.5 inches (1.2cm to 3.7cm), SKF supplies ag-specific conveyor and harvester chains – corn picker, intake, elevator and bucket types.
Application dictates the approach to proper lubrication.
“In dusty conditions the wrong oil becomes grinding paste,” Protheroe says.
“Some drives are best left dry; others benefit from the right lubricant delivered the right way.”
For balers, SKF’s OCLM driven chain lubrication system is built for in-season use.
There is also pre-lubrication at manufacture for OEM programs.
“One corn picker chain for a major OEM took four years to finalise,” van Zyl says.
“Coatings and a specific lubricant had to work together to hit life targets.”
Built to stand out
Seasonal replacement can drive a price-only mindset. SKF’s path has been longer life with sensible cost.
“In South Africa we moved many ag chains to hard-chrome pins,” van Zyl says.
“Not the cheapest, but life improved enough to justify it. The balance matters – extend life without pricing it out of reach.”
SKF always trials chains in contexts where failures are quick to show themselves.
“For harvesters, South Africa’s dry, sandy seasons are as harsh as it gets,” van Zyl says.
Sugar-cane harvester chains are tested in Brazil.
“The same harvester model can run three SKF chain specs – roughly 1,200 hours, 1,500 to 1,800 hours, or about 2,500 hours – with material upgrades at the top tier. Customers pick the life, and price tracks the spec.”
Having tried and true chains tested in harsh climes is a boon for Australia, where demand for ag sizes is rising.
“Distributors build stock ahead of harvest and see repeat orders,” Protheroe says.
“Growth has been organic – which suggests the product is doing the talking.”
Van Zyl adds that volumes in transmission chain for agriculture keep climbing year on year.”
Complete package
“The advantage is the package,” Protheroe says.
“Chain, lubricator, lubricant – and for OEMs, matched sprockets too.”
Van Zyl points to a new program of idler sprockets with integrated SKF bearings rolling out from Europe and the US.
“When the pieces are designed to work together, service gets simpler – and the drive lasts longer,” he says.
Exceptional life without premium-only pricing is the throughline, with Protheroe saying SKF’s cost-to-performance ratio sits with the biggest names.
Van Zyl links it to SKF’s global footprint and learning loop.
“Prove it in South Africa and Brazil, then apply it on headers and balers here,” he says.
“Make it consistent. Spec it correctly. Prove it in the toughest conditions. Do those three, and the chain earns its place on the machine.”
