PSL610-305 Metric Tapered Roller Bearing

Thin-Section Design: 170mm inner bore with only 220mm outer diameter provides maximum shaft clearance in compact gear housings.
High Rigidity: Optimized roller complement ensures high radial dynamic load ratings and minimal deformation under stress.
Separable Design: Outer ring (cup) can be installed separately from the inner ring and roller assembly (cone).
Thermal Stability: Special heat treatment allows reliable performance under high operating temperatures.

Source PSL610-305 (170x220x27mm) large metric tapered roller bearings. High-precision design for steel mills, heavy machinery, and industrial gearboxes.

Product Introduction

The PSL610-305 is a high-capacity, large-diameter metric tapered roller bearing designed for heavy mechanical engineering applications. Measuring 170 x 220 x 27 mm, this thin-section bearing offers an exceptional strength-to-weight ratio, allowing engineers to maximize shaft diameter while reducing total equipment mass. Forged from vacuum-degassed GCr15 steel with super-finished raceways, the PSL610-305 minimizes rolling resistance and thermal expansion under heavy loads. Global B2B buyers count on this model for continuous-duty machinery, metallurgical equipment, and industrial drivetrains.

Applications

Metallurgical rolling mills and continuous casting equipment.
Heavy industrial gearboxes and speed reducers.
Large centrifugal pumps, blowers, and marine propulsion drives.

FAQ

Q: Can this bearing be used in paired configurations?
A: Yes, single row tapered roller bearings are commonly mounted face-to-face or back-to-back to manage bi-directional thrust loads.
Q: What precision grades are available?
A: Standard production is ISO P0 / ABEC-1; higher precision grades (P6 or P5) can be manufactured upon request.
