Cylindrical Roller Bearings FAG N306 -E-XL-TVP2

The FAG N306 -E-XL-TVP2 cylindrical roller bearing, an open idler bearing measuring 30 × 72 × 19 mm, is designed to accommodate radial forces in mechanical engineering applications.

The N306 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing in tolerance class P0/PN (corresponding to ABEC 1). Compared to ball bearings, cylindrical rollers provide a linear contact surface on the raceways, meaning the bearing is designed to withstand high radial loads. As an open rolling bearing without integrated seals, this design is characterised by low rotational resistance and is supplied with grease or lubricating oil via an external lubrication system.

In which installation scenarios is the N306 -E-XL-TVP2 cylindrical roller bearing used?

This design is primarily used as a non-locating bearing in bearing arrangements subject to high radial forces. In the N design, the outer ring has no flanges, meaning that axial length changes in the shaft due to thermal effects are compensated for directly within the bearing. The permissible temperature range is between –30 and +120 degrees Celsius. As the outer ring has no lubrication bore and no circumferential groove, the lubricant is supplied via the surrounding bearing housing.

What are the distinctive features of the N design with a polyamide cage?

The outer ring can be removed from both sides, which simplifies installation and subsequent inspection work. The inner ring and roller cage can be mounted on the shaft and in the housing independently of the outer ring. The polyamide cage (TVP2) guides the rollers with low mass whilst maintaining normal radial clearance. In the open design, the surrounding structural elements must provide protection against dirt particles and moisture.
