Custom RYOBI Offset Press Rubber Rollers
Product Overview:
AstraRoll manufactures high-precision replacement rubber rollers for RYOBI offset presses. As shown in the images, our product line features two distinct profiles: cylindrical rollers for ink and water transfer units, and tapered ductor rollers for precise ink feed control.
Standard material is premium NBR (Nitrile) with station-specific hardness (30–35 Shore A for ink, 25–30 for water). Every roller is CNC-ground to ensure perfect nip pressure and is custom-machined to your specific OEM drawing or physical sample—guaranteeing a true drop-in fit for models from the A3 520 to the B1 920 series.

Custom RYOBI Offset Press Rubber Rollers Details
Product Overview
AstraRoll‘s Custom Rubber Rollers are engineered as direct-fit replacements for the inking and dampening units of RYOBI offset presses, covering models from the compact 520/524 to the large-format 680/750/754/920 series. Replacing worn, glazed, or swollen rollers is critical for maintaining ink film thickness and preventing print defects.
Our range features two distinct profiles (as shown in the product images):
Cylindrical Rollers: Used for ink form, distributor, and water form positions. Machined with multi-step metal journals for stable rotation and uniform nip pressure.
Tapered Ductor Rollers: Used at the ink fountain to control the ink feed profile, ensuring precise ink film thickness across the entire press width.
