4T-CRI-0760 35x64x37mm Double Row Tapered Roller Bearing – Automotive Air Conditioner & Wheel Hub Precision Component
Product Overview
The 4T-CRI-0760 is a high-precision double row tapered roller bearing designed specifically for demanding automotive applications. With its compact dimensions of 35x64x37mm, this bearing delivers exceptional radial and axial load-carrying capacity in a space-efficient package, making it an ideal solution for automotive air conditioning compressors, wheel hub assemblies, and other critical rotating systems.
Engineered with GCr15 chrome steel and premium rubber seals, the 4T-CRI-0760 ensures reliable performance under harsh operating conditions, including temperature fluctuations, moisture exposure, and high-speed rotation. Its double row design provides enhanced stability and load distribution compared to single-row alternatives, significantly extending service life in automotive environments.

Double Row Tapered Geometry – The tapered roller configuration enables the bearing to handle combined axial and radial loads simultaneously, providing superior rigidity and precise shaft positioning essential for automotive wheel hub and compressor applications.
High-Grade Chrome Steel (GCr15) – Manufactured from vacuum-degassed GCr15 bearing steel, the 4T-CRI-0760 offers excellent wear resistance, high hardness (HRC 60–64), and exceptional dimensional stability even under sustained heavy loads and elevated temperatures.
2RS Rubber Seals – Integrated dual-lip rubber seals on both sides effectively prevent contaminant ingress (dust, moisture, road debris) while retaining lubricant, ensuring maintenance-free operation and extended service intervals.
Nylon Cage – Lightweight, wear-resistant, and self-lubricating, the reinforced nylon cage minimizes friction, reduces operating noise, and allows for higher rotational speeds compared to steel cages.
P0 Precision & C3 Clearance – Standard ISO P0 precision class paired with C3 radial internal clearance ensures optimal running accuracy and thermal compensation, particularly beneficial in applications with intermittent high-speed operation and temperature variations.
Materials & Quality Assurance
| Component | Material Specification | Key Properties |
|---|---|---|
| Rings & Rollers | GCr15 Chrome Steel | High hardness, wear resistance, fatigue strength |
| Seals | Nitrile Rubber (NBR) | Oil resistance, temperature range -40°C to +120°C |
| Cage | Engineering Nylon | Low friction, high impact strength, chemical resistance |
| Lubricant | High-temperature grease (pre-filled) | Extended life, stable viscosity |
All bearings undergo 100% quality inspection covering dimensional accuracy, radial runout, noise testing, and seal integrity checks, in compliance with ISO 9001 manufacturing standards.
