H715334/H715311 Imperial Tapered Roller Bearing 61.912x136.525x46.038mm

Extreme Thrust Capacity: The steep contact angle and extra-wide 46.038mm profile allow this bearing to handle massive unidirectional axial loads alongside heavy radial weight.
Severe Shock Resilience: Deeply case-hardened alloy construction resists catastrophic failure and raceway spalling under severe mining and construction impact loads.
Precision Hand-Fitting: Manual assembly ensures that the oversized rollers are perfectly matched to the raceway, eliminating the edge-loading risks common in mass-produced heavy bearings.
Thermal Endurance: Built to maintain tight tolerances even when operating under high heat in continuous heavy-duty industrial cycles.

Product Introduction

The H715334/H715311 is an extreme heavy-duty (H-Series) imperial tapered roller bearing built to survive the most punishing industrial environments. With a 61.912 mm (2.4375 in) bore, a massive 136.525 mm (5.375 in) outer diameter, and an exceptionally wide 46.038 mm (1.8125 in) profile, this bearing features a high contact angle and oversized rollers to manage severe radial and thrust loads. Carefully hand-assembled to guarantee flawless load distribution, this GCr15 steel bearing is a critical component for B2B clients supplying heavy-duty mining equipment, construction machinery, and severe-service industrial differentials.

Applications

Heavy off-highway truck differentials and pinion shafts.
Mining crushers, vibratory screens, and large-scale material handling conveyors.
Severe-service industrial planetary gearboxes and heavy winches.

FAQ

Q: What does the "H" prefix in H715334 stand for?
A: It designates a "Heavy" series bearing, indicating it is designed with a larger cross-section and rollers to handle significantly higher loads than standard series bearings of similar bore size.
Q: Do you offer heavy-duty packaging for these large bearings?
A: Yes, due to their significant weight and industrial application, we use customized heavy-duty wooden crates and specialized VCI barrier films to ensure safe export delivery.
