Don Dye Company Inc. is a U.S. manufacturer of high‑quality pressed‑steel idler/guide pulleys. Don Dye pulleys form a complete, economical, self‑contained unit for flat and V‑belt applications.
Key features and benefits:
- Premium bearing: single‑row radial ball bearing made from 52100 bearing steel, precision‑ground and pre‑lubricated; contact seals retain lubricant and protect against dust, dirt, and contaminants. Filled 60% with high‑temperature grease—no re‑lubrication required.
- Enhanced shaft support: the inner ring is extended on both sides to provide clearance for abutting parts and greater support on the shaft.
- Patented fit (US Patent No. 4518372): a compression ring between the bearing’s outer surface and the pulley’s bearing pocket ensures a firm, reliable fit, distributes load evenly to the outer race, and minimizes distortion.
- Durability: testing has demonstrated longer, more reliable bearing life.
- Versatility: adapts with little or no modification to new designs or retrofits on existing machines.
