Product Description

The BE‑NK 38.5×67×17 Cylindrical Roller Bearing is a high‑capacity, inner‑ring‑less bearing specifically engineered for transmission and gearbox applications. With a bore diameter of 38.5 mm (designed to run directly on a hardened shaft), an outer diameter of 67 mm, and a width of 17 mm, this bearing offers a compact solution for high‑radial‑load environments where space is limited.

Key Specifications & Features

• Model Number: BE‑NK 38.5×67×17

• Bearing Type: Cylindrical roller bearing without inner ring (NK‑series design)

• Dimensions: ID 38.5 mm (shaft diameter) × OD 67 mm × Width 17 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 meet different application needs

• Seal Type: Open design – enables 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

Design & Performance

This bearing features a full‑complement cylindrical roller arrangement without an inner ring. The rollers run directly on the hardened and ground shaft journal, eliminating the inner ring to save radial space and increase the roller diameter for a given envelope. This design delivers exceptional radial load‑carrying capability and shock resistance, making it ideal for high‑speed and heavy‑duty rotating assemblies. The open construction allows efficient lubrication and cooling, while the lack of a cage reduces component complexity and enhances reliability under extreme conditions.

Application

Primarily used in automotive transmissions, gearboxes, and planetary gear sets, this bearing is also suitable for industrial gear drives, construction machinery, and pump assemblies where high radial loads and compact dimensions are critical. Its inner‑ring‑less design is particularly advantageous for applications with a hardened shaft that can serve as the raceway.

Quality & Certification

Manufactured from premium GCr15 bearing steel under strict quality control (ISO 9001:2000‑compliant processes), the BE‑NK bearing ensures stable performance, low vibration, and extended service life. Each unit is inspected for dimensional accuracy and running smoothness to meet or exceed OEM standards.
