The Vo-Tech V-Block Rollers are a patent-pending, multi-use precision system for checking runout on shafts and cylindrical components. Engineered for quality control, inspection, mechanical assembly, and precision measurement work, the system delivers accuracy of better than ±0.0002″ T.I.R. on roller attachments while supporting components from 1/8″ to 12″ in diameter and loads up to 5,000 lb.
Interchangeable attachments — heavy- and light-duty roller bearings, bronze and Delrin V-blocks, and indicator holders — let a single base support a full range of inspection scenarios without re-tooling. Tool-free quick-change setup and adjustable leveling feet make the system equally usable on the bench, in a dedicated QC station, or on a shop floor that isn’t perfectly flat. Each set is compatible with Starrett and Interapid indicators and ships in a custom-fit foam-lined carrying case.

The V-Block Roller system is deployed across precision inspection environments where shaft and cylindrical component runout must be verified to tight tolerances:
Each V-Block Roller system is configured and manufactured to order at Vo-Tech’s Crystal Lake, Illinois facility. Configuration, attachments, and rail length are specified at order to match the inspection application.
