PSL610-304 Thin-Section Metric Tapered Roller Bearing
- Thin-Section Design: Large 220mm bore diameter relative to its 265mm outer diameter allows machinery designers to maximize hollow shaft sizes in tight housings.
- High Rigidity & Capacity: Precision-ground rolling elements evenly distribute heavy radial dynamic loads across raceways.
- Separable Construction: Cup (outer ring) and Cone (inner ring assembly) mount independently for streamlined installation and maintenance.
- Heat Treated Core: Thorough heat treatment ensures long raceway fatigue life and resistance to shock loading.

Product Introduction
The PSL610-304 is a specialized, thin-section metric tapered roller bearing engineered for heavy mechanical applications where radial envelope space is strictly limited. Featuring a large 220mm inner bore with a compact 265mm outer diameter and 25mm total width, this bearing offers an exceptional strength-to-weight ratio. Manufactured from vacuum-degassed GCr15 chrome steel with super-finished raceways, the PSL610-304 manages simultaneous radial forces and single-direction axial thrust while minimizing structural weight. It is an ideal, high-precision component for global B2B distributors supplying heavy industrial drive and gearbox manufacturers.
Applications
Industrial speed reducers, rotary tables, and indexing drives.
Steel mill equipment and heavy processing machinery.
Large centrifugal pumps, blowers, and hollow-shaft transmissions.
FAQ
Q: What is the main advantage of the thin-section PSL series?
A: It provides a very large shaft passage (220mm bore) while keeping the outer housing envelope extremely compact (only 265mm OD).
Q: Can this bearing be installed in pairs?
A: Yes, single-row tapered bearings are frequently mounted back-to-back or face-to-face to handle bi-directional axial loads.
