Product Description
Tapered Roller Bearing 31305 for Pinion Shaft and Reduction Gearbox Taper Roller Bearing
Product Overview

The 31305 Tapered Roller Bearing is meticulously engineered to accommodate heavy combined radial and axial loads simultaneously. Characterized by its steep angle design, this single-row metric tapered roller bearing delivers exceptional axial stiffness and superior running accuracy under severe thrust stress. It is widely used in heavy-duty gearboxes, vehicle axles, and rotating industrial machinery where reliable shaft alignment, high load ratings, and low operational friction are strictly required.

Key Advantages
  • High Combined Load Capacity: Optimized steep taper angle efficiently manages simultaneous heavy radial and high single-direction thrust forces.
  • Separable and Interchangeable Design: The inner ring with ball/cage assembly (cone) and the outer ring (cup) can be mounted independently, simplifying system assembly and maintenance.
  • Premium High-Grade GCr15 Steel: Advanced hardening and heat treatment processes maximize core toughness and significantly extend rolling fatigue life under torque stress.
  • Enhanced Roller Profile Geometry: Logarithmic contact profiles on rolling elements optimize stress distribution and eliminate edge loading concentration.
  • Ultra-Low Noise & Low Friction: Super-finished raceways minimize parasitic drag and heat generation, ensuring smooth power transfer at high rotational speeds.

Frequently Asked Questions
Q1: Can a single 31305 tapered roller bearing accommodate bidirectional thrust loads?

No. A single row tapered roller bearing like the 31305 can only support axial forces acting in one direction. To accommodate bidirectional thrust loads or to position a shaft rigidly in both directions, these bearings are almost always mounted in pairs (either back-to-back or face-to-face arrangements) with proper preloading.

Q2: Why does the 31305 model feature a steeper angle than standard tapered roller bearings?

The 313-series is intentionally designed with a steep contact angle. This modification significantly increases its axial load-carrying capacity relative to its radial rating, making it highly effective for applications dominated by heavy thrust loads, such as pinion drives.

Q3: What quality certificates does your factory hold for international industrial exports?

Our manufacturing plants are fully certified under ISO 9001:2015 global quality management guidelines. We maintain comprehensive tracing from raw materials to final dimensional audits to guarantee uniform international consistency.

Q4: How do you package the bearings to prevent rust during long-distance maritime shipping?

Every bearing undergoes an anti-rust oil dip, is vacuum-sealed in a medical-grade plastic bag, packaged into an individual neutral box, and packed onto reinforced, moisture-wrapped plywood cases or pallets to completely block saltwater corrosion.
