PU Coated Roller with 686ZZ Bearings for Labeling, Packaging and Small Conveyors
If your labeling machine, laminator or small packaging line needs a quiet idler roller that won't leave marks on film or paper, this PU coated version with double 686ZZ bearings is a straightforward option. The polyurethane surface gives better grip and lower noise than metal, while the pre-installed bearings keep rotation smooth under continuous light loads.
The roller is non-powered. It turns only when material or another roller drives it, so it works well as a feed, guide or pressure roller in compact automation setups.
What Makes It Practical
Double 686ZZ deep groove ball bearings are fitted from the start. This cuts assembly time and keeps rolling resistance low. The outer polyurethane layer is wear-resistant and soft enough to protect labels, films and printed materials. Hardness can be set anywhere from Shore 50A to 90A so you can match the surface to the material you handle most.
Key points from actual use:
Quiet running compared with rigid metal rollers
Less risk of scratching or marking delicate surfaces
Custom diameter, length and shaft style available
Suitable for continuous operation in labeling and packaging equipment
Common Applications
Label dispensing and labeling machines
Packaging and film-handling equipment
