Product Description

The CR‑07B11 Cylindrical Roller Bearing is a precision‑engineered, single‑row cylindrical roller bearing designed specifically for automotive differential and powertrain applications. With a bore of 34 mm, an outer diameter of 75 mm, and a dual‑width design (inner ring width 16 mm / total width 21 mm), this bearing offers high radial load capacity and reliable performance in a compact form factor.

Key Specifications & Features

• Model Number: CR‑07B11

• Bearing Type: Cylindrical roller bearing (with steel cage)

• Dimensions: ID 34 mm × OD 75 mm × Width (B/T) 16/21 mm

• Material: GCr15 chrome steel – high hardness, excellent wear resistance, and extended fatigue life

• Precision Grades: Available in P0, P6, and P5 accuracy classes to suit different assembly tolerances

• Seal Type: Open design – allows efficient lubrication and heat dissipation

• Cage: Steel cage – securely retains rollers, reduces friction, and enables higher speeds compared to full‑complement designs

• Rolling Elements: Cylindrical rollers (provide high radial rigidity and low friction)

Design & Performance

This bearing features a cylindrical roller geometry with line contact between rollers and raceways, ensuring even load distribution and high radial stiffness. The steel cage maintains precise roller spacing, minimising roller‑to‑roller friction and allowing operation at elevated speeds. The open construction facilitates easy lubrication and effective cooling, which is essential for differential applications subjected to continuous high‑speed rotation and variable loads. The separable inner and outer rings simplify mounting and dismounting during assembly and maintenance.

Application

Primarily engineered for automotive differentials, this bearing is also widely used in gearboxes, transfer cases, axle drives, and other power‑transmission components where high radial loads and moderate thrust loads are present. Its robust construction makes it suitable for passenger cars, light trucks, and commercial vehicles.

Quality & Certification

Manufactured from premium GCr15 bearing steel under ISO 9001:2000‑compliant quality control processes, the CR‑07B11 delivers consistent performance, low vibration levels, and long service life. Each bearing is inspected for dimensional accuracy, running noise, and clearance to meet or exceed OEM specifications.
