SET1119 Imperial Tapered Roller Bearing 38.1x79.375x29.37mm

Compact High-Load Design: Maximizes load-carrying capacity within a restricted radial cross-section.
Low Friction Operation: Finely honed raceways and optimized roller profiles ensure low operating temperatures even at high rotational speeds.
Separable Components: The cone (3490) and cup (3420) can be installed individually, simplifying assembly in deep housings.
Case-Hardened Core: Provides excellent resistance to shock loads and prevents raceway spalling under heavy acceleration.

Product Introduction

The SET1119 is a compact yet highly resilient imperial tapered roller bearing designed for automotive and mid-sized industrial applications. Featuring a 38.1 mm (1.5-inch) inner bore and a 79.375 mm outer diameter, this set combines the 3490 cone and the 3420 cup to deliver exceptional performance in tight housing envelopes. Manufactured from high-grade GCr15 chromium steel, it is engineered to sustain high-speed rotations and moderate-to-heavy radial loads, making it a standard replacement part for automotive differentials, transaxles, and precision industrial machinery.

Applications

Automotive and light truck differential pinions.
Manual transmissions and transfer cases.
Agricultural PTO (Power Take-Off) drives and small gear reducers.

FAQ

Q: Is the SET1119 suitable for high-speed differential applications?
A: Yes, its precise roller alignment and low-friction cage design make it ideal for the high RPMs found in automotive pinion shafts.
Q: Can you supply this model in bulk without individual boxes?
A: Absolutely, we offer bulk industrial packaging (nested in tubes or trays) for OEM assembly lines to reduce waste and cost.
