Bellows are designed to protect extended upper punches from contamination by sealing off the full punch barrel. They help keep oil and powder away from the compression zone, which reduces the risk of tablet defects and keeps your press running smoother for longer. Ideal for sticky, oily, or dusty formulations, LFA’s bellows are flexible, easy to clean, and made from high-quality materials. Use them to improve press reliability and maintain a cleaner production environment.
Protect Extended Punches from Powder and Oil Contamination
Bellows are specially designed for presses using extended upper punches. They cover the full length of the punch barrel to keep lubricants and fine powders from migrating into the compression zone or reaching the tablet surface.
This extra layer of protection helps avoid issues like oil-stained tablets, powder infiltration in moving parts, and failed inspections due to residue buildup.
Key Features:
✅ Designed specifically for extended punch barrels ✅ Compatible with multiple tooling sizes ✅ Made from flexible, FDA-compliant material that holds up to repeated cleaning and compression cycles ✅ Available in multiple styles to suit different press configurations and product requirements ✅ Helps extend tooling life and reduce unplanned downtime
Bellows are ideal for production runs using oily lubricants, sticky granules, or abrasive powders. They're a low-cost solution that helps protect your press and reduce overall maintenance.
What are bellows used for in tablet press machines?
Bellows are used with extended upper punches to prevent powder and lubricant from reaching the compression zone or getting on the tablets.
What’s the difference between bellows and dust cups?
Dust cups are typically shorter and used for standard punches. Bellows are longer and designed to cover the full length of extended punch barrels, offering more protection.
Why should I use bellows on extended punches?
Bellows help prevent oil from dripping onto tablets and powder from entering the upper guides. This reduces defects and keeps your press cleaner between runs.
Are LFA bellows compatible with my press?
LFA bellows are compatible with B tooling, D tooling, and 1-1/4" punches. They’re made to OEM specs and available in different styles to fit your machine.
What are LFA bellows made from?
They’re made from flexible, FDA-compliant material designed to withstand routine cleaning and resist wear from abrasive powders and lubricants.
How do I know when to replace bellows?
Replace bellows if they show signs of stretching, cracking, or contamination buildup. It’s a good idea to check them as part of your routine maintenance.
Can I get help choosing the right bellow for my setup?
Yes. Contact the LFA team and we’ll help match the correct size and style for your press and punch configuration.
