32312 / 7612E Single Row Tapered Roller Bearing 60×130×48.5mm | Cr=285kN Cor=310kN | 6100rpm | Automotive, Tractor & Industrial Machinery Bearing

The 32312 (ISO/DIN designation) is a Single Row Tapered Roller Bearing with boundary dimensions of 60×130×48.5mm, manufactured to DIN ISO 355 / DIN 720 standards. Also designated 7612E under the GOST system, it is fully interchangeable with FAG 32312-A, NSK HR32312J, NTN 32312U, SKF 32312B, and Timken 32312.

With a dynamic load rating of 264–285 kN and static load rating of 310 kN — confirmed consistently across FAG, Timken, and RS-Online official data sheets — the 32312 delivers robust combined radial and axial load capacity for a 60mm bore bearing. Its 6,100 rpm reference speed enables use across a wide range of industrial and automotive applications requiring both high load capacity and high rotational speeds. The fatigue load limit of 51 kN further confirms its suitability for long-life, high-cycle industrial applications.

At just 2.96 kg, the 32312 is the lightest bearing in the upper 323xx series, providing an outstanding load-to-weight ratio. Its steel sheet metal window cage (roller-guided) and open (unsealed) design make it compatible with all standard external lubrication systems used in industrial and automotive machinery.

Product Specifications

Key Features & Engineering Advantages

• ✅ Single Row Tapered Roller Design (DIN ISO 355 / DIN 720) — Handles combined heavy radial and axial loads in one direction; separable design allows independent mounting of inner and outer rings

• ✅ Cr=264–285kN / Cor=310kN (3-source confirmed) — Static load rating of 310kN confirmed independently by FAG, Timken, and RS-Online official data, ensuring high reliability for heavy-duty applications

• ✅ Fatigue Load Limit Pu=51kN — Precisely defined fatigue threshold enabling accurate bearing life calculations under variable load conditions

• ✅ 6,100 rpm Reference Speed — Highest reference speed in the 323xx series at this bore size, enabling use in high-speed automotive transmissions, industrial gearboxes, and tractor drivetrains

• ✅ Lightest in Class at 2.96kg — The most compact and lightweight member of the upper 323xx series, delivering outstanding load-to-weight ratio for space- and weight-sensitive 60mm shaft applications

• ✅ Steel Sheet Metal Window Cage — Roller-guided cage provides superior roller guidance, retention, and lubrication distribution under high-speed and high-load conditions

• ✅ Separable Design — Inner ring (cone) and outer ring (cup) are separable, facilitating easy installation, adjustment, and replacement in the field

• ✅ Adjustable Preload / Clearance — Can be used adjusted or in pairs, enabling precise axial preload setting for stiff shaft arrangements

• ✅ HRC 60–64 Hardness — Premium GCr15/52100 chrome steel with precisely controlled hardness for exceptional wear resistance and fatigue life

• ✅ Full Global Interchangeability — Directly interchangeable with FAG 32312-A, NSK HR32312J, NTN 32312U, SKF 32312B, Timken 32312

• ✅ Multi-Precision Options — P0/P6/P5/P4/P2 precision grades available for standard to ultra-precision applications

• ✅ Tractor & Agricultural Proven — Listed under NEXANS tractor bearing category, confirming field-proven performance in agricultural drivetrain applications

Typical Applications

Based on the bearing's 60mm bore, 264–285kN dynamic load rating, 310kN static load rating, 6,100rpm reference speed, and single-row tapered roller design:
