Product Description

The CR‑07B10 Cylindrical Roller Bearing is a high‑capacity, full‑complement bearing designed specifically for automotive differential and transmission applications. With a bore of 35 mm, an outer diameter of 77 mm, and a dual‑width design (inner ring width 17 mm / total width 22 mm), this bearing offers robust radial load support in a compact package.

Key Specifications & Features

• Model Number: CR‑07B10

• Bearing Type: Cylindrical roller bearing (full complement, without cage)

• Dimensions: ID 35 mm × OD 77 mm × Width (B/T) 17/22 mm

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

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

• Seal Type: Open design – facilitates easy lubrication and heat dissipation

• Cage: No cage – full complement of rollers maximises roller count for increased radial load capacity

• Rolling Elements: Cylindrical rollers (not balls) – provide high radial rigidity and low friction under heavy loads

Design & Performance

This bearing features a full‑complement cylindrical roller arrangement without a cage. The omission of the cage allows more rollers to be packed into the same envelope, significantly enhancing radial load‑carrying capability and shock resistance. The cylindrical rollers ensure line contact with the raceways, distributing loads evenly and reducing contact stress. The open construction permits efficient lubrication and cooling, which is critical for high‑speed differential operation. The separable inner and outer rings simplify mounting and dismounting during maintenance.

Application

Primarily engineered for automotive differentials, this bearing is also suitable for gearboxes, transfer cases, and other powertrain components where high radial loads and compact dimensions are required. Its robust design makes it ideal for both passenger cars and light‑duty commercial vehicles.

Quality & Certification

Manufactured from premium GCr15 bearing steel under ISO 9001:2000‑compliant processes, the CR‑07B10 guarantees stable performance, low vibration, and extended service life under demanding operating conditions. Each unit is inspected to meet or exceed OEM standards.
