Key-Bar Pneumatic Shaft

Product Features

• Tweak the Dimensions Your Way：You aren't stuck with one standard size. We can customize the body lengths, diameter specs, and even the number of keys running down the tube to match your exact machinery setups, so the shaft slides right into your bearings without a hitch.
• Painless Locking and Release：The no-nonsense pneumatic hookup design means your operators can inflate the bladders to secure a new reel or drop the pressure to slide an empty core off in just a few seconds, which helps trim down your slow changeover times.
• Tough Steel Build for Heavy Rolls：We machine these shafts from high-strength steel so they have the structural muscle to handle massive web weights and continuous industrial abuse without bending or flexing under load.
• Zero Drama Maintenance Routine：Standardized internal parts and a flexible frame layout mean that if a bladder eventually wears down, teardowns and seal replacements are pretty straightforward tasks that won't bog down your mechanics.
• Practical and Smart for Your Budget：The specialized mechanical layout delivers a highly reliable way to keep your modern web-processing equipment running safely without over-complicating things or breaking the bank.

Product Applications

• High-Speed Printing Equipment

Installed on press lines to help operators stage up wide paper, vinyl, or packaging reels quickly, ensuring everything stays locked tight during high-speed ink runs.

• Rewinding Stations

A practical choice for fast-moving rewinders where you are constantly pulling completed rolls off and need a mandrel that grabs the new core right away.

• Industrial Slitting Machinery

Applied across slitting equipment to provide heavy roll support and keep your material ribbons from walking sideways while the knives are working.

• Heavy-Duty Paper Mills

Drop them deep inside papermaking systems that handle massive, oversized web weights all day long and need a core holder that won't wimp out.
